Vertex data compression method and apparatus for compressing vertex data through analyzing channel properties and related vertex data decompression method and apparatus

摘要

A vertex data compression method includes: collecting a plurality of vertices as a vertex block; extracting at least one data unit array from the vertex block, wherein each data unit array is composed of data units selected from vertex components of the vertices respectively, the data units correspond to a same channel, and each data unit is smaller than one byte; and for each data unit array, checking the data units of the data unit array to select a compression algorithm, and compressing the data units of the data unit array according to the selected compression algorithm.
