虚拟人行走的动作融合

研究在行走时虚拟人动作与虚拟地形之间的交互性。通过碰撞检测来确定人体在地面之上的正确位置。利用动作融合的方法,即将几个典型动作按合适的权重结合产生新的动作数据,实时地驱动虚拟人并使之对环境变化的反应满足视觉上的逼真性。融合过程中各原始动作的权重取决于沿着和垂直于人体运动方向的2个地面坡度,同时也通过对地形的几何分析来实现虚拟人对其周边地形的感知。

Motion Blending of Virtual Human in Walking Locomotion

A study is performed on the interactivity of virtual humans with the virtual terraifi during locomotion by walking. Collision detection is implemented to locate the walker correctly above the ground in the virtual world. Approach of motion blending is employed to generate new motion data to animate in real-time the virtual humans in a believable reaction to the change of environment. The blending weights of the walking motion are determined by the two gradients of the terrain along and across the locomotion direction. Geometric analysis on the terrain is also carried out for the virtual humans' perception to the terrain around.
