The present concepts relate to lossless data compression techniques for reducing the size of a data structure. Certain data in the data structure that can be either recovered from another source or rebuilt from other available information may be removed from the data structure. To further reduce data size, the retained data in the data structure may be packed into a smaller-bit encoding data type. Additionally, to reduce the data size even more, the packed data may be zipped using a lossless data compression algorithm. To regain the original data structure, the process may be reversed. The zipped data may be unzipped using a lossless data decompression algorithm. The packed data may be unpacked into the original bit-sized data encoding. The removed data may be restored by either recovering it from another source or rebuilding it from other available information.

Data compression

Methods and devices for rendering graphics in a computer device include receiving, at a graphics processing unit (GPU), a memory location address of a portion of a primitive to be rendered along with an indication of one or more values of one or more pixel shader parameters for the portion of the primitive, selecting, by the GPU, a pixel shader from a plurality of possible pixel shaders based on the indication of the one or more values of the one or more pixel shader parameters, and generating, by the GPU, at least one output of a render target of the portion of the primitive based on applying the pixel shader to the portion of the primitive.
