Attempting to do texturing, getting an accessviolationexception

Posted Thursday, 20 October, 2011 - 23:51 by patrickm in

Hi again All,

I'm trying to get texturing to work now, and having some trouble with it, I get an accessviolationexception on my drawelements call. The project is here, I was hoping someone could take a look.

I'm pretty sure it has something to do with the way I'm setting up GL.InterleavedArrays, or my vertex structure, I'm just not sure how exactly to diagnose this issue. I tried the debug version of the library and didn't really get any more information.

Ok, I've got it working, but it just displays a black cube now. All I changed was the line:

GL.InterleavedArrays(InterleavedArrayFormat.T2fN3fV3f, 0, IntPtr.Zero);

in mesh.bindvertexbuffers, to:

GL.VertexAttribPointer(0, 2, VertexAttribPointerType.Float, false, 32, 0);
GL.VertexAttribPointer(1, 3, VertexAttribPointerType.Float, true, 32, 8);
GL.VertexAttribPointer(2, 3, VertexAttribPointerType.Float, false, 32, 20);

Black cube is better than error message, but I'm not sure what is still wrong...
