Abstract
In a computer graphics processing unit (GPU) having a texture unit, when pixel sample locations are based on a non-orthonormal grid in scene space, the texture unit receives texture space gradient values directly, e.g., from a shader unit or generates them from texture coordinates supplied, e.g., by a shader unit, and then applies a transformation to the gradient values configured to adjust the gradient values to those which would arise from the use of a orthonormal screen space grid.
