摘要:
A method for implementing LOD (level of detail) filtering in a cube mapping application. The method includes accessing a first sample and a second sample for a cube map. A cube map path is computed between the first sample and the second sample. A distance is computed between the first sample and the second sample, wherein the distance is measured using the cube map path. LOD filtering is then implemented by using the distance between the first sample and the second sample.
