Hello Bill,
please check the possibility to port SG3d or an enhanced version to
VOGL. Please do not use OpenGL.
VOGL, an OpenGL/GL clone supports a lot of 3D-graphics. I already saw
two programs, GRAPE, an object orientated 3D-visualization tool and
VIS5D, a powerful tool for the visualization of meteorological datasets.
The advantage of VOGL is, it's free!!!!!!
I think, it is very important to use no commercial product!
Greetings
Andreas Holz
