Fur effect with visual basic (vb6) and opengl using vbCg.dll to accede to the NVIDIA's Cg toolkit. This one is the first offer to achieve the effect, it would be great if someone more wanted to contribute other methods or algorithms to reach the maximum performance and / or the maximum quality in the same one. In this offer, there is in use a vertex shader and a fragment written in Cg language for manipulating two textures simultaneously. One of the textures contains only random pixels in a way similar to the white noise of the tv, this is the one that we manipulate of such form that gets extruded in the direction of the normal one doing that as it moves away along the same one become less and less visible. VbCg.dll only it takes charge calling to the functions in Cg.dll and CgGL.dll using the correct calling convention.
