Abstract
The disclosure provides an approach for a hybrid binding of meshes. Multiple meshes having levels of detail appropriate for different regions of a model are topologically connected by binding them together at simulation time. In one embodiment, a simulation application creates both geometric and force bindings between vertices in meshes. The simulation application identifies embedded vertices of a first mesh to be bound to a second mesh as being “best” bound vertices, such as vertices coincident with vertices in the second mesh, and geometrically binds those vertices to appropriate vertices of the second mesh. The simulation application then binds each of the remaining embedded vertices which cannot be geometrically bound to vertices of the second mesh via a force binding, in which a zero-length spring force based technique is used to transfer forces and velocities between the force bound vertex of the first mesh and vertices of the second mesh.
