摘要给出空间任意一点到等腰四面体4个面有向距离的一个定值性质。 - The three axes determine three planes , the - , - and - plane . which divide space into eight octants . to each pointin space corresponds an ordered triple of numbers . its cartesian coordinates , which measure its directed distances from the three planes
三个坐标决定三个坐标面,面,面,面,这些坐标面将空间分成八个卦限,空间中点每个点都对应一个有序三元组和分别表示点到三个坐标面的有向距离 - 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
本文的主要贡献在于：在扫描体逼近计算方面，在原有任意多边形网格模型沿任意路径运动生成扫描体逼近算法的基础上，提出了加入对扫描母体简化的预处理和用活动标架对扫描路径进行重采样等过程，算法的其它过程还包括：计算扫描体中几何基元的排列，用硬件加速构造无符号的有向距离场，将无符号距离场转化为有符号距离场，从有符号有向距离场提取等值面等。
