Hybird Drive For Interactive Character Animation

With the computer animation to be used more and more extensive in every fields, character animation as an important part of computer animation is developing rapidly. It's very difficult to produce high quality human motion animation or design related algorithms.In order to create a real, natural animation which can be real-timely interacted with scene, scholars, who are from home and abroad, have been committing to the research of different character control mode. First of all, this thesis introduces the critical technologies about different modes of character movement control, and then uses the hybrid control mode to resolve the problems which appear in the situation of the character motion caused by the sole control mode. The problems to be studied and solved are as follows:1. On the basis of analysis the structure of motion capture data file(BVH) and the structure of Ogre's file, we create new data structure to load motion data. Then we use the data to driving mesh do different animations and blending multi-BVH file is accomplished.2. On the premise of that character animation drived by motion data, to avoid the condition that foot of character under ground or suspending. We get the information of character's pose and environment, do inverse kinematics to modify the character's pose.3. To make sure the moveable character in scene can response to the impact real time, first we create the constraint between bones, then set the controller(damping model) for each constraint ,which provide the torque to drive the character, to do rigid body simulation.This thesis takes the interactive scene of oilfield minor repairs as an example, mixes kinematics and dynamics, motion capture, finally obtains character animation by hybrid control in interactive environment .
