Why I can not use GL_DOUBLE in linux

OpenGL
1

hi,

I tried a few opengl programs. every time, I
use “glutInitDisplayMode” function with GLUT_DOUBLE. the program with crsh the whole
system, I had to shut off the compter by switch off the power.

If I do not use GL_DOUBLE, all animation flicks. I think GL_DOUBLE should not be a
big requirement for a video card. I got ATI
rage 128. same program works well on Windows 98

Anyone can tell me why?

Thanks
Hill

don’t use it unless you need double buffering because you have moving graphics, and do not have GLUT_DEPTH. If your prog comes up with a blank screen it might be a color problem. (don’t make the bouncing square it sucks)
