How to convert Okino Transfer File (.bdf) to OpenGL C Code (.cpp)?


PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

     

Okino Transfer File

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).

     

OpenGL C Code

OpenGL is a cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Okino's OpenGL 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.
