Abstract
A processor receives a request to access one or more levels of a partially resident texture (PRT) resource. The levels represent a texture at different levels of detail (LOD) and the request includes normalized coordinates indicating a location in the texture. The processor accesses a texture descriptor that includes dimensions of a first level of the levels and one or more offsets between a reference level and one or more second levels that are associated with one or more residency maps that indicate texels that are resident in the PRT resource. The processor translates the normalized coordinates to texel coordinates in the one or more residency maps based on the offset and accesses, in response to the request, the one or more residency maps based on the texel coordinates to determine whether texture data indicated by the normalized coordinates is resident in the PRT resource.
