I've been working on a little model of the earth. I have a shader which reads a texture to figure out what country is at a specific spot of the world, and recolour it based on that. However, in order for this to work, I have to disable filtering on the textures of the material (as I'm just using a ...

I'll try some of those suggestions out, thanks a lot.
One thing which isn't exactly clear, is what data type is the pointer which you get using ITexture::lock()? Visual Studio says it's a "void*" but that doesn't make much sense. It doesn't matter that much as I'll probably use one of the less slow ...
