Thus, you get the base OpenGL C program to represent your 3D scene (geometry, lights, camera, textures, etc).

dsp/.dsw project and workspace are output in addition to the frame work to an OpenGL application program. This benefits OpenGL rendering quality in cases where the extents of the scene cause the OpenGL clipping planes to be spaced too far apart scaling the scene smaller allows the clipping planes to be kept closer together and thus reduce rendering anomalies (due to limited precision in the Z buffer). Options to automatically have the scene rescaled to a user specified maximum size or some absolute size, as well as options to center the geometry at the origin and/or make the geometry sit on the Z=0 horizontal plane.This reduces the number of vertices that have to be transformed by OpenGL. The Okino triangle stripper algorithm is used to take any form of geometry data and turn it into optimized tri-strips for use by the OpenGL tri-strip data type.Vertex positions, vertex normals, uv texture coordinates and vertex colors can all be output. Mesh data can be output as unrolled loops or "vertex arrays" for high performance output.Each geometry object is output to the OpenGL C file as its own function definition (ie: "Sphere#1" is enclosed in a function like: Sphere#1()).

Please note that each object is output as a separate C code function in the resulting file. In addition, the surface definitions (materials) associated with each polygon is used to set up the OpenGL shading parameters. The database is output as a series of polygons with vertex positions, normals, colors and texture coordinates. The resulting program can then be compiled and used to draw the 3d database directly using OpenGL. This geometry export converter writes out the scene database as a C code program in the Open GL scene description language.
