Abstract:
Techniques are disclosed relating to interpolation for texture mapping. In some embodiments, a graphics unit includes circuitry configured to map a texture to a screen space such that a set of multiple in the screen space falls between first and second adjacent texels of the texture in a first dimension. In some embodiments, the graphics unit also includes texture processing circuitry configured to perform different types of interpolation for pixels in the group of pixels. In these embodiments, this includes determining pixel attributes for first and second end groups of pixels in the set of pixels using a nearest-neighbor interpolation technique and attributes of the first and second texels respectively. In these embodiments, this also includes determining pixel attributes for an intermediate group of pixels in the set of pixels using a second, different interpolation technique and attributes of both the first and second texels.
