Hi all…
I’m using my own projection matrix along with glOrtho to raster my polys the problem I seem to be having is the textures distort/shear as though their being rendered without perpective distortion/correction. Back in glide days and even D3D you explicitly pass 1/W along with U/W and V/W to the rasterizer. My question is when you call [glTexCoord2f(u,v) glVertex3f(x,y,z)] pairs, does OGL utilize the Z value passed in by glVertex when using glOrtho as the projection matrix? Also my code works great if I use gluPerspective which tells me OGL might be distroying my Z values?!?!? You might ask why does this guy not want to use the OGL transform pipeline?? Simply because my engine supports other API’s but only at the lowest rasterization level (i.e. I have a complete T&L pipeline) just want to use OGL as another rasterizer.
-Best regards
