The trueSpace geometry export converter writes out a trueSpace compatible object or scene file, complete with all geometry and material
attributes. A file exported to trueSpace should render almost exactly as whence the file originated (ie: a 3DS MAX file exported to trueSpace should
render almost exactly the same as it would in 3DS MAX).
The following geometry information is output to the file:
N-sided polygon geometry with recursive holes.
Texture (u,v) coordinate data.
All hierarchy information.
All pivot point information for each object.
In addition, complete trueSpace materials are output to the file including:
Surface color, ambient shading coefficient, specular shading coefficient, opacity value, highlight size and index of refraction.
Spherical environment maps, texture maps and bump maps (including the (u,v) offset and scaling parameters).
Dialog Box Options
File Format = .cob, .scn
These radio buttons determines whether the trueSpace file is to be written in the .scn file format or the .cob file format. The .cob format is best if you only want to transfer geometry data whereas the .scn file format includes camera and light information.
Center All Geometry At the Origin
If this checkbox is enabled (checkmarked) then all the geometry data will be positioned so that it is centered about the origin. If disabled then the geometry will not be repositioned. The default is disabled.
Make Geometry Sit on the Z=0 Horizontal Plane
If this checkbox is enabled (checkmarked) then the geometry will be repositioned so that it is sitting flush with the top of the Z plane (the horizontal plane). The default is disabled.
Auto-Facet Angle
This angle determines the cut-off angle between abutting polygons which are to appear smooth and those that are to appear faceted. The default is 40 degrees. Higher values will make the geometry appear more smooth regardless of how angular the data may be whereas smaller values will make the data appear more faceted. To change this value within trueSpace enable the "Inspect Face" mouse option, click on an object, then in the "shader/maps" modeless dialog box right click on the "autoFacet" icon (middle button on the left side).
Scale Geometry to be no Large Than...
Many objects exported to trueSpace are typically too large for the default 20x20 grid shown in the trueSpace user interface. This option allows the geometry data to be automatically rescaled if it is too large. If set to 'Do not scale the geometry' then no scaling will be done. If set to '1x1x1 units' then all the objects will be scaled smaller should they exceed 1x1x1 units in total size. Likewise for the '2x2x2 units' option. If set to 'User defined maximum size' then the maximum size of all the objects can be set using the type-in numeric box.
Output Enables
The following options control what is sent to the .scn or .cob file:
Hierarchy Information
If this checkbox is enabled (checkmarked, which is the default) then hierarchy information will be output to the file, else the geometry will be output with no hierarchy.
Texture (u,v) Coordinates
If this checkbox is enabled (checkmarked, which is the default) then (u,v) texture coordinates will be output to the file, else the (u,v) texture coordinates will be set to (0,0).
Texture Bitmap References
If this checkbox is enabled (checkmarked, which is the default) then references to bitmap textures will be output along with the material definitions in the .scn file.
Materials
If this checkbox is enabled (checkmarked, which is the default) then materials will be output to the file.
Camera 'Views'
If this checkbox is enabled (checkmarked, which is the default) then the 'Vews' chunk will be output to the .scn file which defines the various camera locations.
Lights
If this checkbox is enabled (checkmarked, which is the default) then lights will be output to the .scn file.
