Vertex Attributes

[Jan]

Ok, i've been an idiot, but now i got it to work.

In glVertexAttribPointer i passes as "size" (second parameter) the size of the array in bytes.

However it does expect the number of components of the attribute (1,2,3 or 4). And due to some tests, the code that also contained "glGetError" was commented out, which meant, that i didn't see the "invalid value" error, that GL threw at me.

Thanks for all your help and clarifications!

Back to speed optimizations...

Is it possible, that generic vertex attributes are not well supported under nVidia? I got my code working just fine on ATI now, but on a friends PC with a Geforce 7 i get corrupted output (polygons missing) and program crashes.

Any other ideas, what could cause such behaviour? My rendering code is pretty much straight-forward.

i have worked a lot with these vertex attributes - no problems on nvidia till now

Same for me - no problems with vertex attributes on both ATI and Nvidia.
