The Design And Achievement Of The System Of The Virtual Human Path Edition Based On The Path Changing

Computer animation, which is an important branch of computer graphics, has been widely used in many fields. But traditional animation method has a disadvantage about low-efficiency. So traditional animation method can not meet the marketing demand. Furthermore, path edition is a key technique about motion editing. So here we have a deep research about path edition techniques.The research about virtual human technology tech of virtual people has the important sense and function for the research about fields of computer animation, spaceflight, military and so on. This paper designs and implements a virtual human path editing algorithm based on path warping. Its steps includes: first to initialization data, the cycle and the control frames are calculated according to the analysis about data of motion capture; then to warp the path with suggesting a way to insert the control frames based on the step length; then we introduce a way to increase the leg length to put the foot under constraints; moreover, we generate the data; after that, we go on the smooth transition by dynamic programming; we suggest a method to deal with the towards treatment about the virtual people to come into a high-quality path editing animation. Result have validated proposed algorithm can perform path editing well and make the edited animation more realistic. Compare with the algorithm of predecessors, this algorithm doesn’t have the evident phenomenon of the foot skate when the change of the path is not so large. This paper realizes a system to make user do some operations including path edition. These models make the system have better function about path editing and deal with some questions about frames. Furthermore, they attain the objective about finishing the path editing.
