摘要
提出了Polycube参数化的自动构造技术.该算法首先对网格进行特征分解,然后用立方体组成的一些基本形体逼近分解得到的各部分网格区域,确定基本Polycube的顶点和边在区域上的对应顶点和路径,将各区域进一步分解为面片,从而在构造Polycube的同时完成对曲面的分片,最后再分片参数化并进行面片间的平滑,高效地实现了Polycube的自动参数化.该方法在很大程度上减少了Polycube构造过程中的人工干涉,使其能够在纹理映射等方面得到应用.
An automatic Polycube construction and parameterization method is proposed in this paper. This approach first decomposes the input mesh into a set of feature regions. Each region is approximated by a simple Polycube which is further split into several patches. Since each patch corresponds to a rectangular sub-surface of the Polycube, they can be parameterized independently. A smoothing procedure between patches is performed to reduce the overall parametric distortion. This method makes Polycube parameterization more convenient in texture mapping and other applications.
