I'm a newbie graphics programmer and I've been wondering recently - how does model data (meshes and materials) flow from application (CPU memory) to graphics card (GPU memory?)? Say I have a static ...
I'm doing some graphics optimizing tests, especially on PowerVR transparency. Now I made a scene where there are two groups of simple objects. One group has the shape in geometry using diffuse shader ...
