SIMULATION OF RESIZABLE BODIES USING A RIGID BODY SOLVER

摘要

A computer-implemented method and system automatically adjusts the size of a rigid body model. The method and system construct a two-dimensional model or a three-dimensional model, where the model has one or more rigid bodies. The rigid bodies are converted into geometric primitives that represent a respective rigid body and enable the respective rigid body to resize. One or more of the primitives are constrained to one another. A solver process changes a size of at least one geometric primitive and a rigid body simulation process uses the resized primitive(s) as input.

1. A computer-implemented method for automatically resizing a rigid body model, the method comprising:
using a computer-aided design system, constructing a model, wherein: the model is one of a two-dimensional model and a three-dimensional model; and the model comprises one or more rigid bodies; converting at least one of the rigid bodies into a set of geometric primitives representing a respective rigid body, wherein the geometric primitives enable the respective rigid body to resize; constraining certain members of the set of geometric primitives; executing a solver process on a computer processor, wherein: the solver process changes a size of at least one geometric primitive representing the respective rigid body; and the set of geometric primitives representing the respective rigid body allow the change in the size without user intervention; and executing a rigid body simulation, wherein the one or more resized primitives are inputs to the rigid body simulation.
