Hello,

I use 2D and 3D(ATI RADEON 9200) textures, and I noticed a difference between the 2D & 3D coordinate system of the arrays and the textures ?

For 2D: Tab[line][row] from top left gives a Tex[t][s] from bottom left.

For 3D: Tab[Depth][line][row] gives an identical texture coordinate system Tex[t][s][r].

Is it correct ? Did I something wrong which gave me this result ? Does it depends of the used graphical card and particular extension ?

Thanks in advance for your help and your time.
