摘要： One exemplary process for animating hair includes receiving data representing a plurality of hairs and a plurality of objects in a timestep of a frame of animation. A first tree is populated to represent kinematic objects of the plurality of objects and a second tree is populated to represent dynamic objects of the plurality of objects based on the received data. A first elasticity preconditioner is created to represent internal elastic energy of the plurality of hairs based on the received data. Based on the first tree and the second tree, a first set of potential contacts is determined between two or more hairs of the plurality of hairs or between one or more hairs of the plurality of hairs and one or more objects of the plurality of objects. Positions of the plurality of hairs are determined based on the first set of potential contacts and the first elasticity preconditioner.

摘要： The surface of a body of water can be animated by deconstructing a master wave model into several layer models and then reconstructing the layer models to form an optimized wave model. A wave model is obtained, which describes the wave surfaces in a body of water. The wave model is comprised of a range of wave model frequencies over a given area. A primary layer model, secondary and tertiary layer models are constructed based on portions of the wave model frequencies. An optimized wave model is constructed by combining the primary, secondary, and tertiary layer models. A wave surface point location is determined within the given area. A wave height value is computed for the wave surface point location using the optimized wave model. The wave height value that is associated with the surface point location is stored.
