Hi, I have a wired problem. When I added fog to my application the fog only appears when I run it with MESA libraries (linux). With native OpenGL from NVIDIA or ATI it does not appear!? Is it my fault? Is there any dependency for glEnable(GL_FOG). This is the way a im adding fog: . . . glEnable(GL_DEPTH_TEST); glEnable(GL_FOG); glFogi (GL_FOG_MODE, GL_LINEAR); glFogfv (GL_FOG_COLOR, color); //glFogf(GL_FOG_DENSITY, 0.4); glFogi(GL_FOG_START, start_l); glFogi(GL_FOG_END, end_l); glClearColor(color[0],color[1],color[2],color[3]); . . . Any help is greatly appreciated! I am stuck since 3 days on this... yesterday I tried it first with my old laptop and its MESA libs... Thx Harry

This code looks fine.

Can you please post values of color, start_l and end_l ?

At best, can you also provide screenshots ?
