| 摘 要： | 为提高基于实例的皮肤变形算法的效率和速度,对加权姿态空间变形(WPSD)等算法进行了研究.WPSD中需要的逐顶点计算可以在GPU上以单指令流多数据流(SIMD)方式并行执行.并行顶点计算一般在GPU顶点处理器中执行,但是更进一步的并行操作是可以由片段处理器来获取到的.提出了一种基于GPU片段处理器实现的并行变形算法.每个顶点的关节权值可以由样本姿态自动的计算出,因此减少了手动操作,提高了WPSD等皮肤变形算法的质量.

| Abstract: | To enhance the efficiency and speed of example based skinning algorithm,the weighted pose space deformation(WPSD) and so on are studied.The per-vertex computation required in WPSD is parallelized in a SIMD manner and implemented on a GPU.While such vertex-parallel computation is often done on the GPU vertex processors,further parallelism can potentially be obtained by using the fragment processors.We develop a parallel deformation method using the GPU fragment processors.Joint weights for each vertex are au... |
