I have a pyramid I draw with auto generated texture cordinance. The problem is it does not look the same when I change video cards, ie- The Voodoo3 will map the texture to the object differently than the Rage128, etc… Is there a way to use auto cords and have it look the same every time?
I have the same problem with fog effects. Do different cars render fog differently.
The problem comes with the different implementations of OpenGL. An implementation depends on the card, in fact on driver. So an OpenGL application may works fine on some cards and not on others.
In fact, you have to know if drivers are certified or not.
Will all implementations that have ‘certified’ drivers render the scene the exact same?
Who certifies the drivers?
