Abstract
In a computer graphics processing unit (GPU) having a shader and a texture unit the pixel shader is configured to receive or generate one or more sets of texture coordinates per pixel sample location. The pixel shader and texture unit between them are configured to calculate texture space gradient values for one or more primitives and generate and apply per-pixel gradient scale factors configured to modify the gradient values to smoothly transition them between regions of a display device having different pixel resolutions.
