How to convert I-DEAS 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.

     

I-DEAS

I-DEAS was a CAD software package originally developed by SDRC in 1982. Unigraphics and I-DEAS were merged into "NX" (or Unigraphics NX). Siemens AG would eventually come to own "NX" by 2007 by which time it is now referred to as "Siemens PLM Software".

Okino's VRML importers were tweaked in their early days to specifically import VRML files from the I-DEAS software; this is the preferred method of data translation. Other supported formats are IGES, STL and VDA-FS.

     

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.
