2. Curve Proxy

Curve Proxy要解决的问题

2.1 Skeleton based

Axial Deformation [1994]

取曲面中轴或人为标注的骨架
并建立骨架上的点与边界上的点的关联

2.2 Skeleton‐based Deformation

2.3 Wires based

[Siggraph 1999]

在曲面外围定义轮廓线

2.4 Silhouette sketching based

[Nealen et al. Siggraph 05]

Silhouette （轮廓线）

Approximate sketching: Balance weighting between detail and positional constraints

实现的思想类似于Laplace，只是交互的方式变成了Stretch。

2.5 Volumetric Graph Laplacian

[55:32] 保证体里面的Laplace，相当于2D Laplacian 推广到3D。
能保证体不收缩，即局部保体积。
