How to convert KeyCreator (CADKEY,.prt,.ckd) 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.

KeyCreator

KeyCreator is a non-parametric, non-history based, "direct" 2D/3D solid modeling CAD program. Originally known as CADKEY, it was among the first CAD programs with 3D capabilities for PCs. Besides solid modeling, KeyCreator is also capable of wire-frame and surface modeling, as well as drafting.

KeyCreator has good support for exporting to all of the major 3D file formats, including STEP, ACIS SAT, IGES, Parasolid, STEP and STL. STL is the least desireable format to use. Recommended formats for importing KeyCreator data into Okino software is ACIS SAT, IGES and Parasolid.

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.
