when I use ARB texture compression together with SGI mipmap generations extension I get rasterization errors. It’s kinda hard to discribe. Sometimes there are white seams between triangles and I’m 100% sure that it’s not the T junction problem. This is the code:
glTexParameteri(GL_TEXTURE_2D, GL_GENERATE_MIPMAP_HINT_SGIS, GL_NICEST);
When I use bilinear filtering instead of trilinear or if I enable anisotropic filtering in the driver these white seams are gone. Using GL_RGB instead of GL_COMPRESSED_RGB_ARB removes the seams too.
Any Idea what’s wrong with my code ?
