基于参数的NURBS体体素化与布尔运算(英文)
Parameters-based voxelization of NURBS volumes and its Boolean operation
【摘要】 主要讨论基于参数的NURBS体体素化与并、交、差布尔运算。这是一种能比较精确表示NURBS体的体素化算法。NURBS体造型技术主要有蒙皮法、拉伸法与旋转法等。影响NURBS体形状的因素有控制顶点、结点与结点的重度、权因子与基函数次数。
【Abstract】 Parameters-based voxelization of NURBS volumes and their Boolean operation such as union,intersection and difference are discussed mainly.Thisis anew kind of voxelization algorithm which can more exactlyexpress the volume.The methods forconstruction of NURBS volumes include skinning,sweeping and swinging etc.
