arbitrary mesh meaning in Chinese
任意网格
Examples
- Arbitrary mesh handling : the proposed method can handle meshes with arbitrary topologies , such as meshes with arbitrary number of genus
变形物体拓扑结构任意:因为区域可由用户指定，而对变形物体的拓扑结构无特别要求。 - In general , there are two types of ffds : deformation with a lattice and deformation with constraints . we present an approach to deform arbitrary meshes based on geometric primitives
另一类是基于“约束”的，约束可以是一个空间的点、线、面或几何体，求解满足给定约束偏移的物体形变。 - In computation of swept volume approximation , an improved technique to generate the swept volume approximation for arbitrary meshes is presented by introducing generator simplification and path resample using frenet moving frames along the discreted sweeping trajectory . other steps , such as a directed distance field computation on a uniform grid based on the hardware accelerated computation technique and iso - surface extraction using marching cubes algorithm , are also included in this algorithm . in addition , the simplification scheme and smoothing technique are applied to the swept volume generated from iso - surface extraction
