Method and system of real-time graphical simulation of large rotational deformation and manipulation using modal warping

摘要

A real-time simulation method and system for large deformations is provided in which the rotational component of an infinitesimal deformation is identified, and linear modal analysis is extended to track that component. Small rotations occurring at the nodal points are integrated. By implementing both position and orientation constraints, shape of a deformable solid is manipulated by dragging/twisting a set of nodes. Large bending and/or twisting deformations is simulated.
