The invention discloses a flexible material deformation simulating method and device and belongs to the field of computers. The method comprises the steps of judging whether collision happens to a model according to a preset position of the model at the next moment and the position of a local collision surface of the model, carrying out calculation according to the current position of a collision point of the model and the preset position to obtain the displacement of the collision point of the model at the next moment when collision happens to the model at the next moment, and updating the preset position of the model at the next moment to the actual position of the model at the next moment when collision does not happen to the model at the next moment. According to the flexible material deformation simulating method and device, collision judgment is achieved according to the preset position of the model at the next moment and the position of the local collision surface of the model, and therefore collision detection processes are simplified; calculation is carried out according to the current position of the collision point of the model and the preset position to obtain the displacement of the collision point of the model at the next moment, therefore, calculation is accelerated, and real-time requirements of the simulating process are met.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a deformation simulation method and device for flexible materials. Background technique [0002] With the development of computer software and hardware technology, industries such as animation and games have risen rapidly. Scenes in animation and games are realized through modeling and simulation, and the finite element method is a classic device for solving elastic mechanics problems in the process of modeling and simulation. [0003] The finite element method discretizes the continuous solution area into a group of units, and each unit is connected to each other in a certain way to realize the modeling of the geometrically complex solution area. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] In the prior art, the nonlinear equations need to be solved in the finite eleme...
