Abstract

Methods and systems for texture mapping in a computer-implemented graphics pipeline are described. A sample group is identified as including a divergent pixel. A determination is made whether an operand of an instruction executing on the divergent pixel satisfies a condition. A scheme for determining a level of detail for the texture mapping is selected depending on whether or not the condition is satisfied.
