| 摘 要： | 从构建3D网格出发,使用MPEG-3DMC对构建的3D数据进行压缩。将MPEG-3DMC解压程序移植到基于PowerPC的FPGA平台,对压缩的3D数据进行解压,对解压后的数据先经过定点化再进行渲染。最后在FPGA平台上进行了验证。验证表明,FPGA平台上的平均渲染速度达到25FPS以上,3DMC解码后渲染的效果达到了PC机上的效果。

| Abstract: | Starting from building 3D mesh MPEG-3DMC is used to compress the 3D data build by adaptive sampling without bounding box, then the compressed data is decoded using MPEG-3DMC ported to FPGA platform based on PowerPC. After that the decoded 3D data are fix-point processed and rendered. Finally, the program is verifed on the FPGA platform. The verification shows that the average rendering speed on FPGA reaches above 25FPS, and the rendering effects after 3DMC unzipped achieve the same level as that on PC. |
