Description: 设P(m,n)是初始控制点列，即原曲面的点（m行n列）。Q(m,n)是一次细分后得到的曲面的控制节点。
此函数采用Catmull-Clark细分曲面算法，对双三次B样条曲面细分,即m=n=4。
利用我们在13章第四节学过的知识，有公式MQM =SMPM S ,其中M，S可由课件知
构造初始控制点列（p1,p2)，其中p1是P的行坐标，p2是P的列坐标
-Let P (m, n) is the initial control point of the column, i.e. the original surface of the point (m rows n columns). Q (m, n) is the control node of the surfaces one after subdivision. This function takes a Catmull-Clark subdivision surface algorithm, the bi-cubic B-spline surface subdivision, ie m = n = 4. Using knowledge in Chapter 13, section IV, formula MQM, ' = SMPM' S' , wherein M, S by courseware known structure the initial control point of the column (p1, p2), where p1 is the row coordinate of P, p2 column coordinates of P Platform: |

Description: What are Subdivision Surfaces?
The idea of subdivision surfaces was first introduced by Catmull & Clark and Doo & Sabin in 1978. Unlike traditional spline surfaces, subdivision surfaces are defined algorithmically. Recently there has been a lot of activity in the computer graphics research community and significant advances have been made in rendering, texture mapping, animation and compression of subdivision surfaces. They were also used in the production of Geri s Game and A Bug s Life. Geri s hands, head, jacket, and pants were each modeled using a single subdivision surface. The faces and the hands of Flick and Hopper were also modeled with subdivision surfaces. Momentum is building in the computer assisted geometric design (CAGD) to make subdivision surfaces one of the modeling primitives.
