By Prof. Yueting Zhuang, Prof. Yunhe Pan, Dr. Jun Xiao (auth.)

Part of the recent sequence complicated themes in technological know-how and know-how in China, this ebook discusses the suggestions, thought, and middle applied sciences of clever idea and human animation, together with video dependent human animation and clever know-how of movement facts administration and reusing. It introduces structures constructed to illustrate the applied sciences of video dependent animation. every one bankruptcy is self sufficient, whereas energetic images and demos during the textual content assist in making the speculation and applied sciences extra available to readers.

For researchers, this is often an excellent reference booklet and an replace at the present prestige of human animation. For execs, this booklet will function a advisor for software improvement utilizing human animation technologies.
