| 摘 要： | 为了高效而通用地对各种具有复杂结构的药柱进行燃面计算,文中基于图形处理器(GPU)高度并行化的计算构架,提出了一种三维离散化体素点阵表达的燃面计算方法.首先,将药柱所在的包围盒空间均匀地离散戍三维空间体素点阵,通过对边界表达的任意药柱模型进行Z-Buffer测试确定计算边界;其次,采用并行的燃烧状态填充算法确定所有的体...

| Abstract: | To calculate burning surface of complex SRM grains in a more efficient and more generalized way,a 3D discrete voxels-represented burning surface calculation method was proposed.Based on highly paralleled graphics process units(GPU) computing architecture,the bounding box space of the grain was discretized into a 3D voxels matrix firstly,and Z-Buffer testing was used to confirm the calculation boundary of the grain.Then,paralleled burning state filling algorithm was adopted to calculate the distance fields b... |
