In the existing curves and surfaces formulations, a shape is designed by moving the control points of curves or surfaces. 摘要在现有的曲线曲面设计中，曲线曲面的形状是通过控制顶点或数据点来确定的。
Traditionally, surface reconstruction is built directly by using reconstruction data, which control vertexes aren't compressed. 传统的逆向工程曲面重构方法是直接重构，即不对控制顶点进行压缩，直接利用重构数据。
