The following export converters implement the Okino "conversion engine" which ensures that all aspects
of the source 3D data flows through to the desired destination 3D program and/or file format, regardless of
how different or incompatible they are.
Statistically speaking, most of our common hourly customers
would be re-exporting their source data to
3ds Max,
CINEMA-4D,
LightWave,
Maya or
NGRAIN,
or FBX (for Unity or Unreal VR/AR authoring),
even though
we support all main 3D programs and file formats succinctly.
Where supported, the converters output optimized
mesh or NURBS geometry, 3D spline/bicubic and NURBS curves, hierarchy, object/camera/light animation data,
lights, cameras, materials and their associated attributes, texture/tangent/color vertex attributes, mesh skinning weights, skeletons (bones or joints),
meta data, texture bitmaps and scene properties. Files created by these exporters are "Render
Ready" meaning that everything is set up to produce a good rendering on the
first pass with no tweaking necessary (in particular, the perspective camera,
its camera parameters and the lights are accurately translated to the
target rendering platform).
3D Export Format | Ext | Mat | Hier | uv | VC | L&C | Anim | Skel | Skin |
3D Studio R1-R4 | .3ds |  |  |  | |  |  | | |
The export converter writes out the scene database to a 3D Studio file including mesh data, smoothing group information, material attributes, bitmap references, viewport configurations, cameras, lights, and camera plus object animation data (where appropriate). It also provides for automatic bitmap conversion during file export. This converter outputs almost every possible 3D Studio file attribute. For materials, a partial list includes all texture maps (texture # 1, texture # 2, reflect map, bump map, shininess map and opacity map), automatic planar & cubical environment maps, transparency values, phong values and shading modes (flat to metal). Note: the converter also does shading parameter matching so that, for example, colors and textures read in from LightWave will be rendered fairly closely when exported to 3D Studio. Other exported attributes include view port settings, atmospheric effects and background color schemes. Geometry hierarchy, geometry attributes and the first keyframe of the animation section is output. The .3ds file format was the native file format of the old Autodesk "3D Studio R1-R4" software, which was popular up to about 1996 before its successor (3ds Max) replaced it. Having been around since the very late 1980's, it has grown to become an industry standard for transferring models between 3D programs, or for storing models for 3D resource catalogs (similar in status to Wavefront OBJ as a model archiving file format). Please do not confuse the .3ds format with the 3ds Max .max format. You will find throughout the 3D industry that some companies refer to .3ds as the "3ds Max file format" but this is not true. The native file format of 3ds Max is the .max format, whereas .3ds is just a legacy import/export file format ported over to 3ds Max by Tom Hudson during the transition from 3D Studio R4. Suggestion: Do not use the .3ds format to transfer data to/from 3ds Max (especially for huge CAD datasets). There are many people who continue to do this. The best method is to use the directly integrated PolyTrans-for-3dsMax plug-in system. Note that the .3ds format is no longer an ideal file format as it once was. The .3ds format has several serious shortcomings, many of which probably stem from the fact that 3D Studio R1 grew out of Tom Hudson's mid-80's "CAD-3D" on the Atari platform: - All meshes must be triangles.
- All texture filenames are limited to 8.3 DOS character lengths.
- The number of vertices and polygons per mesh is limited to 65536.
- Accurate vertex normals cannot be stored in the .3ds file. Instead "smoothing groups" are used so that the receiving program can recreate a (hopefully good) representation of the vertex normals. This is still a hold-over legacy for many animation programs today which started in the 1980's (3ds Max, LightWave and trueSpace still use smoothing groups, and Maya up to v2.51).
- Object, light and camera names are limited to 10 characters. Material names are limited to 16 characters.
- Directional light sources are not supported.

3ds Max (via PolyTrans-for-3dsMax native plug-in system) | .max |  |  |  |  |  |  |  |  |
Okino has spent more than 2 decades developing the main, professional conversion system for 3ds Max called PolyTrans-for-3dsMax. It allows 3ds Max to directly read and write all the 3D file formats supported by Okino. Please note that it is not possible to import or export .max files directly from inside the NuGraf or PolyTrans stand-alone software itself (see below for explanation); The .max file format is not a pure 3D file format (as is the .3ds file format) but rather it contains a "state snapshot" of how the various plug-in modules with 3ds Max interact with each other to produce the final displayed mesh model. In order to read/write .max files we must run PolyTrans directly inside 3ds Max itself. This is because we need to have 3ds Max evaluate its "stack" of plug-in modules that operate on the base mesh. The evaluated output mesh is then sent to PolyTrans. Vice versa, we need to gain access to the core of 3ds Max to import data from PolyTrans and save it to the 3ds Max internal database. Please note that these special plug-in modules operate INSIDE 3ds Max itself and not inside the stand-alone NuGraf or PolyTrans software. These modules are NOT to be placed in the Okino 'vcplugin' directory. If you wish to transfer data from NuGraf, PolyTrans or Maya to 3ds Max, execute those programs and save out an Okino ".bdf" file. Now load in the .bdf file via the PolyTrans-for-3dsMax plug-in system. |
Acclaim Motion Capture | .amc, .asf | |  | | | |  |  | |
This export converter writes out motion capture data in the Acclaim (.amc and .asf) file format. This file format describes animated skeletons in terms of bones, hierarchy and angle constraints. |
Biovision Motion Capture | .bvh | |  | | | |  |  | |
This export converter writes out motion capture data to the Biovision .bvh file format. This file format describes animated skeletons in terms of joints, hierarchy and angle constraints. |
CINEMA 4D | .c4d |  |  |  | |  |  |  |  |
Okino's CINEMA 4D export conversion system intelligently and robustly converts from the world's most popular and complex 3D programs (MCAD, AEC, DCC, Animation and VisSim) into highly accurate and efficient .c4d files. The conversion is direct, from source file format to .c4d file format, with no usage of the MAXON CINEMA-4D software. Technically, this is the first professional conversion program which can read and write to the .c4d file format (some people may be confused of other programs which support CINEMA-4D v6 format but that has been obsolete since 1998). An overview of its salient technical features can be read here. Refer to the following main documentation: Since mid-1998 Okino has been the primary provider of professional 3D conversion solutions to MAXON Computer'spopular CINEMA-4D animation program (a short historical overview of CINEMA-4D can be found online here). We understand the conversion requirements of CINEMA-4D customers very well and have amassed a large mutual user base of CINEMA-4D customers. |
COLLADA (best for Blender) | .dae |  |  |  |  |  |  |  |  |
Okino provides the main, professional implementation of the COLLADA file format in this exporter system. It is a full featured and well implemented exporter to the COLLADA .dae file format. It supports a variety of 3D geometry output choices, hierarchy, skinning + skeletons, materials, textures, meta data and animation. As a passing note, COLLADA has long been the best 3D file format to import/export with Blender and not FBX (which may surprise many Blender users). Okino has been involed with Blender since its very beginnings and hence tests its import/export converters under particularly stressful conversion conditions. Blender's COLLADA implementation properly supports geometry, hierarchy, part naming, instancing and material conversion. The two runner ups would be FBX and VRML2 but they are not recommended for use with Blender. An overview of its salient features can be read here. Please refer to the corresponding COLLADA importer.

DirectX | .x |  |  |  |  | ¥ |  | ¥ |  |
This export converter writes out ASCII and binary DirectX (.x) formatted files. Mesh data (with vertex normals, vertex uv texture coordinates and vertex colors), materials, texture references, hierarchy and object animation are all exported. In addition, vertex weights used for mesh/skeleton deformation skinning are exported. Automatic bitmap file conversion is done to the PPM and BMP file formats. ¥ = The DirectX file format has no support for lights or cameras. ¥ = DirectX is very much associated with bones and skinning but it has no explicit "bone" primitive. Any hierarchy node in the DirectX file format can act as a bone, just as it occurs in the Softimage dotXSI file format. PolyTrans has very strong and robust support for exporting skeletons and mesh skinning information from various source 3D file formats and animation packages. The main features include: - Proper translation of all forms of geometry into the DirectX 'Mesh' primitive, complete with support for the 'MeshNormals', 'MeshMaterialList', 'MeshVertexColors' and 'MeshTextureCoords'.
- Export of skin weights, from select source programs, for realtime deformation of single skin meshes by their associated bound skeletons (the skeletons are represented as frame hierarchies). New for DirectX 8.
- Export of vertex duplication lists for DirectX 8. In order to output proper uv texture coordinates there are cases when vertices of a mesh have to be duplicated. The vertex duplication list allows the reader of the .X file to undo this duplication process.
- Object hierarchy support by embedding mesh data within a 'Frame' structure.
- Automatic conversion of bitmap files to .bmp or .ppm format. Also, the converter can resize the bitmaps so that they are a power-of-two and square in size.
- The converter can take any arbitrary 3D object (including those with n-sided polygons and optional holes, bicubic patches or NURBS patches) and convert them to optimized triangle meshes.
|
DXF | .dxf |  | | | | | | | |
This export converter writes the scene database as either 3-point or 4-point polygons using the 3DFACE or POLYFACE MESH entities. Polygons with 5 or more vertices, concave polygons, or polygons with holes are automatically triangulated. All polygons will be assigned DXF color # 1. If the file is written using the POLYFACE MESH option then there is no need to weld the geometry data when the DXF file is read into another program (since the data output to the DXF file will be automatically welded by this converter). DWG format, up to the most recent release, is provided in the Okino CAD/Pack license. The base-level Okino software only supports up to DXF R12 (ASCII). |
Electric Image FACT (also good for Form/Z) | .fact |  |  |  |  |  | | | |
This export converter writes out raw FACT files to the Electric Image animation system. FACT files are also a common format to move scene data in and out of the Form/Z modeling program. Please note: if you wish to export animation data to Electric Image Universe then use the LightWave export converter file format. Features of the export converter: - Exports polygonal geometry (or NURBS converted to polygons) with associated vertex normals, uv texture coordinates, vertex colors and tangent vectors,
- Export of complex FACT hierarchy, including the preservation of linkage information and child/parent transformation information. Pivot points are properly exported as linkage information.
- Complex material information is exported:
- Diffuse, specular, ambient and luminance colors.
- Diffuse, specular, ambient and luminance shading coefficients.
- Transparency, reflectivity, index of refraction and diffuse bias.
- Automatically creates a MacBinary Header for ease of use on a Macintosh.
- Converts between Electric Image's left handed coordinate system and right handed coordinate system.
- The ability to selectively export
- Vertex texture coordinates
- Object hierarchy
- Texture bitmap references
- Materials
- All inherited attributes such as position, rotation and scale are properly handled.
- Outputs texture UV coordinates as well as various forms of texture projections (where applicable). Since the size of texture projections depend upon the bitmap resolution of their associated texture maps, this exporter also locates and opens up the texture images to obtain their resolutions.
- The converter can scale and translate geometry during export
|
FBX | .fbx |  |  |  | |  |  |  |  |
Okino was the first professional conversion company to fully implement the FBX file format from its get-go, long before most people even heard of the file format. This geometry export converter writes out Autodesk FilmBox Files (FBX). This export converter supports meshes, NURBS surfaces, spline shapes (converted to meshes or NURBS surfaces), lights, cameras, materials, automatic bitmap conversion, skeleton (bones) and mesh deformation skinning, object animation, camera animation, light animation, material animation and more. Statistically, the Okino FBX exporter has been primarily used for moving data into Unity, the Unreal Engine and MODO. If you are exporting data into 3ds Max or Maya then please use Okino's PolyTrans-for-3dsMax or PolyTrans-for-Maya software. Please refer to the corresponding FBX importer.

HOOPS HSF (WEB Streaming) | .hsf |  |  |  | |  | | | |
This geometry utility saves out the database to the HOOPS Stream File (.hsf) file format. The HOOPS Stream File (HSF) file format allows highly compressed files containing 3D data and bitmap images to be streamed over Internet connections of any bandwidth. The HOOPS Stream File (HSF) format is a robust, customizable and highly compressed 2D/3D visualization format specifically tailored to the needs of displaying 3D model and scene data. Through its rapid widespread adoption and open, published nature, HSF is fast becoming a ubiquitous medium for applications to share visual data and for end users to publish and store their visual data. Advantages of publishing to the HSF Web streaming file format: - No charge for displaying the HSF files on your WEB site. Some other WEB streaming file formats require broadcast license fees or fees to be paid for the publishing package. Okino Computer Graphics has paid a licensing fee upfront to TechSoft America on behalf of our customers.
- Free HSF viewer control for WEB browsers. Available for Windows, UNIX and Linux platforms.
- No WEB server configuration required. HSF streaming and viewing is a client-only solution, eliminating the need to endure the considerable IT burden of server-side configuration and maintenance. Users wishing to implement real time collaborative viewing or view-dependent streaming should refer to the HOOPS Net Server.
- Multiple levels of data compression: vertex, normals, polygon and file-level.
- Level of Detail support. Streams simpler models first, then successively more complex models.
Please also refer to Okino's extensive and popular DWF-3D conversion system which can be used to output .dwf files for viewing with Autodesk's "3D Design Review" software and with other WEB-centric and iPad-centric file viewers. |
Lightscape | .lp |  | |  | |  | | | |
This export converter writes a Lightscape preparation file (.lp) containing all geometry, lights, and material attributes needed to render the scene within the Lightscape Visualization System. Even complicated scenes can be exported quickly and usually require only minimal adjustment from within Lightscape before they can be fully rendered. Lightscape is now owned by Autodesk and integrated into some of their software packages. The main features of the exporter include: - The output of geometry includes vertex normals and texture coordinates for rendering of smooth textured surfaces.
- Support for both layers and blocks within the Lightscape preparation file. Multiple options are available for layer and block structure creation.
- Material definitions are exported including values for transparency, smoothness, index of refraction, and luminance. The exported materials also include texture map information.
- Exported lights include all point and spot light sources with directional lights being converted to point sources positioned some distance outside the extents of the scene geometry.
- Automatic conversion of bitmap files to those formats supported by the Lightscape Visualization System.
|
LightWave | .lwo, .lws |  |  |  |  |  |  | | |
This geometry export converter writes out LightWave compatible object (.lwo) and scene (.lws) files, complete with all geometry, mesh attributes, bones and skinning, hierarchy information, lights and cameras, materials, texture maps, automatic bitmap file conversion, object and camera animation, and material attributes. The following information is output to the object and scene files: - N-sided polygon geometry. All polygons with holes are triangulated.
- Vertex colors and vertex uv texture coordinates (LightWave 6.5 or newer).
- All hierarchy information.
- All pivot point information for each object.
- Point, directional and spot light sources complete with proper location and Euler angle parameters for each light’s first keyframe location.
- Numerically accurate output of LightWave’s default camera location complete with proper location and Euler angle parameters for the camera’s first keyframe location.
- Background colors types (solid or gradient), fog parameters and object attributes (shadowed, casts shadows, etc).
- Object and camera animation data.
- Bones and skinning information in the unusual method that LightWave has chosen to implement.
|
NGRAIN | .3ko, .ngw |  |  |  | | | | | |
The NGRAIN Export Converter for Okino's PolyTrans supports the conversion of all 3D importer formats supported by PolyTrans to the NGRAIN format (3KO). NGRAIN 3KO (3D Knowledge Object) files are used by applications such as NGRAIN Producer and NGRAIN Mobilizer. This NGRAIN Export Converter also allows you to convert 3D files one at a time or by batch conversion. |
OpenGL C Code | .c |  | |  |  | | | | |
This export converter writes out the scene database as a C code program in the Open GL scene description language. The resulting program can then be compiled and used to draw the 3d database directly using OpenGL. The database is output as a series of polygons with vertex positions, normals, colors and texture coordinates. In addition, the surface definitions (materials) associated with each polygon is used to set up the OpenGL shading parameters. Please note that each object is output as a separate C code function in the resulting file. Features of this exporter: - Each geometry object is output to the OpenGL C file as its own function definition (ie: "Sphere#1" is enclosed in a function like: Sphere#1()).
- Mesh data can be output as unrolled loops or "vertex arrays" for high performance output. Vertex positions, vertex normals, uv texture coordinates and vertex colors can all be output.
- The Okino triangle stripper algorithm is used to take any form of geometry data and turn it into optimized tri-strips for use by the OpenGL tri-strip data type. This reduces the number of vertices that have to be transformed by OpenGL.
- Options to automatically have the scene rescaled to a user specified maximum size or some absolute size, as well as options to center the geometry at the origin and/or make the geometry sit on the Z=0 horizontal plane. This benefits OpenGL rendering quality in cases where the extents of the scene cause the OpenGL clipping planes to be spaced too far apart; scaling the scene smaller allows the clipping planes to be kept closer together and thus reduce rendering anomalies (due to limited precision in the Z buffer).
- A Microsoft Visual C++ .dsp/.dsw project and workspace are output in addition to the frame work to an OpenGL application program. Thus, you get the base OpenGL C program to represent your 3D scene (geometry, lights, camera, textures, etc). as well as an OpenGL C program to display the 3D scene in a Microsoft Windows window.
- Removal of redundant coordinates for optimized mesh output.
- Control of color output by weighting of the shading coefficients which are carried over from the imported file format.
- Automatic bitmap conversion from all supported 2D bitmap file formats into whatever you require in your OpenGL C program, with .bmp being the default.

Okino Transfer File Format | .bdf |  |  |  |  |  |  |  |  |
The Okino .bdf file format is the native format used by Okino's PolyTrans and NuGraf products. It is a "snap shot" of the core Okino 3D scene graph database and in essence is a super-set of the capabilities of most 3D files formats. It is the preferred and best file format to use when converting data between 3ds Max (via the PolyTrans-for-3dsMax native plug-in system) and Maya (via the PolyTrans-for-Maya native plug-in system). |
PLY | .ply |  | |  |  | | | | |
The PLY geometry export converter writes out scenes in the Stanford PLY ASCII file format, including mesh attributes such as vertex normals, vertex colors and vertex texture coordinates. An optional material element can also be exported. A PLY file contains the description of exactly one object. The PLY format is NOT intended to be a general scene description language, a shading language or a catch-all modeling format. This means that it includes no transformation matrices, object instantiation, modeling hierarchies, or object sub-parts. It does not include parametric patches, quadric surfaces, constructive solid geometry operations, triangle strips, polygons with holes, or texture descriptions. Typically, PLY files are associated with 3D scanning and object reconstruction. Please refer to the corresponding PLY importer. |
Renderman RIB | .rib |  | |  |  |  | ¥ | | |
This geometry export converter writes out the scene database to a RenderMan RIB v3.1 compliant ASCII file which can then be read into other programs, or more likely, be sent off to PIXAR's RenderMan renderer or the BMRT renderer. The converter exports meshed geometry (with proper segmentation so that shaders are assigned properly), trimmed NURBS, bicubic patches, cameras, lights, embedded material definitions, texture creation commands and animation of frames. Automatic bitmap conversion or filename extension renaming is also performed. The converter writes out a full RIB specification that can be read into a RIB compliant renderer and rendered immediately. The converter primarily outputs optimized indexed polygon arrays using the "PointsPolygon" and "PointsGeneralPolygons" primitives but will also output fully trimmed NURBS patches and (non-trimmed) bicubic patch primitives directly. For your information, Renderman renders trimmed NURBS patches incredibly fast! Camera and object animation data can also be output; a Renderman 'Frame' is output for each frame in the scene, with each frame containing the cameras and geometry translated to that frame's time. ¥ = Keyframe animation will be handled by evaluating the scene at each frame and outputting multiple RIB files, or one RIB file with all frames in it. |
Rhino-3D & OpenNURBS | .3dm |  | |  | |  | | | |
This export converter saves out the database to the OpenNURBS .3dm file format. This is the main file format used by the Rhino-3D NURBS modeling package by Robert McNeel and Associates. The following data is exported to the OpenNURBS .3dm file format: - Trimmed NURBS surfaces (patches) with uv-space and world-space trim curves. The world-space trim curves are calculated at export time by up sampling the uv-space curves to world-space.
- Polygon meshes with vertex normals and vertex uv texture coordinates.
- Independent NURBS curves.
- Spline Shapes as equivalent NURBS surfaces or curves.
- All other geometric primitive are meshed and output as polygon meshes.
- Ambient, point, spot and directional light sources with related parameters.
- Materials with ambient, diffuse, specular and luminous surface colors, phong shininess and transparency. The first diffuse and bump map texture images will also be output.
|
Shockwave-3D | .w3d |  | |  | |  | | | |
This export converter writes out the scene database to the Shockwave-3D file format. This was a WEB Streaming fileformat developed together by Intel and Macromedia. This is not to be confused with the Shockwave or Flash "2D" vector file format. Shockwave-3D is a normal 3D geometry file format with varying levels of lossy data compression to reduce data file size. One primary use of this export converter is to take 3D asset data into the Adobe Director program. The .sw3d files can be imported as 3D assets. Note: the Shockwave-3D file format has more or less been obsolete since 2002 when Macromedia and Intel abandoned the file format. A few years later Intel would push it upon Adobe as the file format of their 3D PDF (U3D) format. The full history is outlined on the Okino U3D exporter page. |
SketchUp | .skp |  |  |  | |  | | | |
Okino's professional SketchUp conversion system intelligently and robustly creates native SketchUp files from almost every 3D CAD, DCC, animation and VisSim program.SketchUp is a popular 3D design product originally developed by @Last Software (http://www.sketchup.com) and now owned by Trimble, Inc. Okino recognized the growing popularity of SketchUp (well before it was purchased by Google and then Trimble) and as such we worked directly with the original SketchUp developer to create the very first set of independent, professional and fully compliant SketchUp 3D converters outside of the SketchUp program itself. Okino's SketchUp conversion system is used throughout the 3D production world by everyone from Disney to LucasFilm to Sony Productions to NASA and many people just like yourself. It handles all the complex problems faced by converting generic datasets into the SketchUp, and especially when dealing with CAD datasets. Please refer to the corresponding SketchUp importer. |
Stereo Lithography | .stl | | | | | | | | |
This geometry export converter writes out the 3d database to an ASCII formatted or binary formatted 'StereoLithography STL' file which can be read by many CAD/CAM related software packages. |
U3D (for 3D PDF) | .u3d |  |  |  |  |  |  |  |  |
Okino's mirror set of U3D import and export converter modules are two of the most well developed and feature rich converter modules available for handling U3D files. U3D files are most often associated with the 3D models which are embedded in Adobe® PDF files. This export converter saves out files in the U3D file format, including meshes, materials, hierarchy, lights, cameras, animation, skeletons (bones) and skinned meshes. The Adobe® Acrobat® PDF viewer does not support all of these entities, particularly skinned meshes. Once a U3D file has been created it can then be embedded into Adobe Acrobat PDF files using the Adobe Acrobat® Pro program. An overview of its salient technical features can be read here. Okino also has a long history involved with the U3D file format. U3D has quite a tainted history in the development community. It was derived from the old Intel IFX 3D gaming toolkit of the 1990's and forced upon developers as the Macromedia 'Shockwave-3D file format' in 2000. The Shockwave-3D format was abandoned in 2002 and then it resurfaced in 2004 when Intel forced it upon Adobe as the 3D file format to use within 3D PDF files (instead of Adobe using the better X3D file format). With the IFX toolkit being so buggy, Okino spent much of 2004 through to 2007 debugging the IFX toolkit and creating the main, defacto implementation of the U3D import/export converters.

VRML1, VRML2, Inventor2 | .wrl, .iv |  |  |  | ¥ |  | ¥ | | |
This export converter outputs clean and detailed files to the VRML 1.0, VRML 2.0 (VRML 97) and a sub-set of the Open Inventor v2 file formats. VRML is an ASCII file format for describing 3d scenes which is primary used in interactive virtual reality applications. You should be made aware that VRML 2.0 is a very good and generic format to transfer data to other 3D programs (ahead of the .3ds (3D Studio) and .obj (Wavefront OBJ) file formats) if you cannot move data in a native form. Features of the VRML 1.0/Inventor v2 export converter include: - Output of clean mesh data with optional vertex normals and vertex texture coordinates.
- Lights (point, spot and directional) and the perspective camera.
- Embedding of any form of texture image inside a VRML file as raw data, or just providing the reference to the texture file.
- Automatic bitmap conversion and automatic bitmap resizing to/from the most popular 2d bitmap file formats.
- Modification controls for bitmap file paths written to the VRML file.
- Material parameter output: ambient color, diffuse color, specular color, emissive color, shininess and transparency.
- Proper segmentation of a mesh into multiple mesh primitives so that diffuse texture maps can be assigned properly.
In addition the following is output when VRML2 format is selected: - Hierarchy for geometry and folders ("null nodes" or "empty instances/objects").
- Export of Object, camera and light animation.
- Vertex colors for mesh data.
- The usage of DEF/USE of the VRML2 file specification to allow instancing of geometry. This can greatly reduce the size of an exported VRML2 file if one mesh, or a sub-set of a VRML hierarchy tree is referenced multiple times.
|
Wavefront OBJ | .obj |  | |  | | | | | |
This geometry export converter writes out the scene database as a series of optimized indexed polygon meshes (faces and their associated indices) along with optional normal and texture data (if its exists within the database). A Wavefront material definition file (.mtl) can also be exported which supports all material and texture options (ie: Ka, Ks, Kd, map_Ka, map_Kd, map_Ks, map_Bump, etc). The export converter also features extensive automatic 2d bitmap conversion options and features (see dialog box description below). ¥ - The Wavefront OBJ file format does not have support for hierarchy, vertex colors, animation, lights, cameras, skinning or other more common scene file contents. The Wavefront file format is quite robust and is a popular format used to transfer entire object geometries between 3D packages. No hierarchy information is output since the .OBJ file format has no methods to describing hierarchy; each sub-object of a hierarchy will nonetheless be exported as a unique group whose name's match the original object names in the internal database hierarchy. |
X3D | .x3d |  |  |  |  |  |  | | |
Okino's X3D exporter (and corresponding importer) are one of the first set of production-quality X3D and Classic VRML converters to come to market, just as Okino had provided the first industry standard set of re-purposing converters for VRML1 and VRML2 in 1996 and 1998 respectively (and which are still two of our most popular file formats today, a decade later). They were developed in full cooperation with the Web3D Consortium and the U.S. Navy."X3D" is the next generation standard, a superset of the VRML2 specification. It is an Open Standards XML-enabled 3D file format to enable real-time communication of 3D data across all applications and network applications. It has a rich set of features for use in engineering and scientific visualization, CAD and Architecture, Medical visualization, Training and simulation, multimedia, entertainment, educational, and more. Where VRML1 and VRML2 dominated the 3D market for the last decade, it is expected that X3D will become the successor and replacement for the next decade. More information about the X3D file format and initiative can be found at www.web3d.org. |
XAML-3D and free viewer | .xaml |  |  |  | |  |  | | |
The Okino XAML exporter acts as a middleware tool. It imports from almost every major 3D CAD, DCC and VisSim file format, then optimizes/reduces/composes the scene data, after which the scene data is exported cleanly out to an ASCII .xaml file. Downstream UX authoring programs then import the 3D XAML files to compose a .NET user interface. For example, this exporter can take complex 3D scenes from Maya, 3ds Max, CINEMA 4D, Maya, Softimage, Lightwave, all major CAD assembly formats, (and many other 3D programs), turn them into compliant XAML files, then use them for Microsoft Windows button creation, hit targets, form controls, and much more in a downstream UX design program. As part of Okino's long term commitment to Microsoft's XAML initiative, we have developed a very nice and useable 2D/3D XAML viewer which is being made available to the XAML community for free. We have spent several years working with XAML and during that time we had found it quite difficult to (1) easily locate the known free XAML viewers via Google, (2) find one which implemented the features we required as part of our critical 3D data translation work. |
XGL | .xgl |  |  |  | | | | | |
This geometry export converter writes out ASCII XGL formatted files as well as their ZGL compressed equivalents. Triangular mesh data (with vertex normals and vertex uv texture coordinates), material properties, embedded texture images and object hierarchy are exported from the XML-style XGL file.The XGL file format is most often used to convey data from several CAD packages into Okino software (such as SolidWorks, Solid Edge, Autodesk Inventor, etc). This exporter can be used to convert all of the Okino supported import file formats to the XGL format. |
