hello,
I am new to this list and hopefully this is the right place to send my questions to. I am fairly new to Performer 2.0, IrisGl/OpenGL and their capibilites, I have an understanding but not very technical, so please stay with me. We use these tools for military training purposes to show the ability to roam around a 3D virtual world. We use dted data and lay terrain over it. We were originally working on IRIX 5.3 on a Crimson Reality Engine and have ported to 6.2 on an Onyx. We brought the IGL libraries over to the new system. When we run the "Stealth" view, in debug mode, there seems to be a problem with loading textures. There also apprears Warning: PfGeoState. When I move around the 3D environment and zoom in on the terrain, lots of tiny black dots appear, but only to a certain point on the screen while looking into the distance. I believe the term is "graininess".
To try to make it simple, what are the major differences, pitfalls to look out for going from 5.3 to 6.2 in terms of IGL and OGL. I am assuming that OGL function calls are non-existent and need to be, since there were no problems using 5.3. I hope this makes some sense. Any help would be greatly appreciated. thanx in advance
