The keeper's note
A contact-based object deformation modeling system for simulating how objects deform when they touch or collide.
Abstract
There are provided systems and methods for performing object deformation modeling. One example system includes a hardware processor, a system memory, and a contact-based deformation modeling software stored in the system memory. The hardware processor is configured to executethe contact-based deformation modeling software to receive a first object geometric data corresponding to a first virtual object and a second object geometric data corresponding to at least a second virtual object, and to transform the first object geometric data by ann-dimensional mapping onto an object deformation space determined based on n primitive deformations. The hardware processor is also configured to execute the contact-based deformation modeling software to model a deformation of the first virtual object due to contact with at least the second virtual object, based on the n-dimensional mapping and a definition of direction for an object-to-object contact force.
