Method and Apparatus for Processing Texture Mapping in Computer Graphics by Biasing Level of Detail According to Image Content and Computer Readable Storage Medium Storing the Method |
摘要 |
A method for processing texture mapping by biasing level of detail (LOD) according to image content includes: a texture request for fetching a target texel is received. The texture request includes a target texture coordinate at a target LOD of a target texture mipmap corresponding to the target texel. A target level of content (LOC) bias map corresponding to the target texture mipmap is looked up according to the target texture coordinate and the target LOD to fetch a target LOC bias value corresponding to the target texture coordinate at the target LOD. A replacement LOD is calculated according to the target LOD and the target LOC bias value. A replacement texel is fetched at a corresponding coordinate, which corresponds to the target texture coordinate, at the replacement LOD of the target texture mipmap. Texture filtering is processed according to the replacement texel.
