    Interactive Virtual Clay Using Implicit Surfaces and Particle Systems

Session/Category Title:   Deformable Objects



    This sketch presents a virtual clay model developed for interactive virtual clay works that require realtime computation and rendering. Ordinary modeling software for 3D free-form objects has a lot of parameters to tune and a number of limitations on the object’s topology and geometry due to underlying mathematical descriptions. Therefore, users must have enough mathematical knowledge and flexible spatial recognition to apply geometric and topological operations to free-form objects. Such problems in free-form modeling can be solved by regarding the objects as clay that can be deformed freely. When users can deal with objects in the same way they would deal with real clay, handling of free-form objects becomes very easy and user-friendly. To realize this modeling concept, virtual clay model must deform in real time.
