Embodiment Construction

[0006] A 3D graphics skeletal animation drawing algorithm based on a smart phone platform, characterized in that the algorithm comprises: utilizing 3D design software to make skeletal animation, said skeletal animation including basic bones and compound bones; The information is imported into a text format animation information file. When exporting, the composite bones and basic bones will be arranged in groups of 4, and each vertex information will be assigned a bone group number and 4 weight information; use The data conversion and packaging tool converts the animation information file in text format into a binary format file for games; the underlying rendering end reads and analyzes the animation file in binary format, multiplies the bone matrix list by weight, obtains the vertex position, and realizes the rendering of the final vertex. All the above-mentioned algorithms are performed on the mobile phone user terminal, and the grouping, arrangement, and weight distribution a...

Abstract

The invention provides a 3D (three-dimensional) skeletal animation rendering algorithm based on a smart mobile phone platform. Animation information is exported into a text formatting animation information file by a 3D software export plug-in, the text formatting animation information file is converted into binary formatting file special for games by a data conversion and package tool, and every four composite bones and basic bones are grouped and arranged. Grouping number of one bone and four weight information can be distributed for each vertex type data. The binary formatting animation file is read and analyzed by a bottom rendering terminal, and final vertex rendering is realized by means of animation matrix list of weights of each group of bones. The 3D skeletal animation rendering algorithm can be applied to development of 3D network mobile phone games on the smart mobile phone platforms or development of 3D application programs such as 3D design software, so that skeletal operation of mobile phone platforms is optimized, real-time calculus 3D animation speed is increased, and data security is improved. Accordingly, the 3D skeletal animation rendering algorithm has the advantages of high reliability, convenience in use, popularization easiness and the like.

Description
