USING CURVES TO EMULATE SOFT BODY DEFORMATION

摘要

Using curves to emulate soft body deformation in a computer-generated character is disclosed. A method can include accessing a reference model mapped to one or more deformation curves for the character. The reference model can include a mesh of vertices representing a soft body layer of the character. The deformation curve can include multiple sample points selected for mapping. Each mesh vertex on the model can be mapped to each sample point on the curve to establish a relationship between them for deformation. The method can also include receiving a movement of one or more sample points on the curve to a desired deformation position. The method can further include calculating primary and secondary movements of the mesh vertices on the model based on the movements of sample points. The method can move the mesh vertices as calculated to a desired deformation position and output the reference model with the moved vertices for rendering to emulate the soft body deformation of the character.
