How to convert Rhino (.3dm) 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.

Rhino

The '.3dm' file format, otherwise known as 'OpenNURBS', is the primary and native file format of the Rhino NURBS modeling package by Robert McNeel and Associates.

Okino was one of the earliest companies to recognize and support the McNeel Rhino software. We have natively supported the Rhino .3dm file format since the release of Rhino v2.0 and up to the current versions of the .3dm file format.

Okino also supports many of the other CAD and non-CAD file formats that Rhino can import and export.

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.
