I have made a small demo of a spinning cube base on NeHe''s 6th tutorial...and it works FINE on my machine. ( p3 733mhz with a 3dfx voodoo 3) but when i send this to my friends some of them have reported to me that it displayed the error message : "Can''t create a GL Context". If i look it the code it is because it did not find a suitable pixel format...or did it? please tell me how to fix this error... This god of mine relaxes, world dies I still pay taxes.

well, it might be that youre friends computer isnt capable of the pixel depth youre setting it to. example, i set the depth of the rendering context to be 24 bpp and it didnt work, then i set it to 16 and it worked.

but whatever, that might not be it. hope it helps though.

i had the same problem a while back. It might be that you have to change the display settings for windows to 16-bit color and it should work fine on your friends computer if they have a card that supports OpenGL and 16-bit mode.

I don''t think so....the computers which showed the error were 3d accelerated.
some of them had
RIVA TNT
VOODOO1
and they support opengl and 16 bit rendering.
I don''t know how to fix it..
NeHe wrote down the functions but he didnt REALLY explain how they work with the opengl interface.

changing the display settings in windows to 16bit colors worked for me

voodo boards require the icd from 3dfx or a minigl thing (these are included woth the latest dirvers and the nvidia equvilent are included in there latest drivers) the desktop HAS to be set to 16 bpp on some video bords especially the voodo borads for some reason. NeHe depth buffer ois always set to 16 bpp unless u have vhanged it whivh u shopuld for ure own computer as you have a v3 which has a 24 bit z buffer (works on my v3 -3000)
