Fast and Robust Inversion-Free Shape Manipulation
2016
Computer graphics forum (Print)
Figure 1 : A band of surface vertices on a tetrahedralized bunny is constricted to a tight noose. Even with severe distortion, the resulting mesh is inversion-free, i.e., all tetrahedral elements have positive volume. Abstract We present a shape manipulation technique capable of producing deformations of 2D and 3D meshes, guaranteeing that no elements will be inverted. We achieve this by augmenting the quadratic ex-rotated elastic energy with additional convex terms that penalize the presence
