Cloth animation processing method and device, electronic equipment and storage medium

Abstract

The invention provides a cloth animation processing method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a cloth grid model and a skeleton chain, the skeleton chain comprises a dynamic skeleton configured with a dynamic skeleton algorithm, and skeleton configuration skeleton animations of which the levels are greater than a preset level in the skeleton chain; determining a first-level animation of the cloth grid model according to the skeleton animation and the animation of the dynamic skeleton; obtaining a dynamic vertex and a cloth constraint corresponding to the dynamic skeleton in the cloth grid model; performing physical simulation calculation on the dynamic vertex according to the cloth constraint to obtain a second-stage animation of the cloth grid model; fusing the first-stage animation and the second-stage animation to obtain a cloth animation of the cloth grid model; the second-level animation adopts the dynamic vertexes corresponding to the dynamic skeletons, and the dynamic vertexes are less than the vertexes of the cloth grid model, so that the simulation calculation amount is small, the consumed performance is low, the modeling dynamics of physical simulation calculation is easy to control, and the skeleton animation only needs to be made for part of skeletons.

Problems solved by technology

[0003] In related technologies, the cloth simulation is a physical simulation based on the vertices of the mesh model, and the soft dynamics of the cloth are simulated by constructing a variety of spring and damping constraint networks between the vertices. The cloth simulation is based on the simulation operation of discrete points Large quantities make it difficult to achieve large-scale use; at the same time, the cloth simulation based entirely on the constraint relationship has so many points and parameters involved in the simulation, it is difficult for animators to adjust the cloth to the shape dynamics they need, and they can only let the simulation results Control, which brings great difficulties to animation performance
