Abstract

In the previous years, Virtually Reality has become a useful tool for simulations and computer games. Collaborative-networked Virtual Reality Environments, allow users having suitable Virtual Reality devices, to interact in a shared virtual world with other participants. Realistic deformation plays an important role in computer graphics, games, simulations and VR environments. Soft body simulations are used to change an object shape, when external forces are applied on it. With the use of term soft body, we mean a mesh, which can change its initial shape when interacting with other physical objects. In virtual reality environments, the user is able to use hand controllers or other devices to interact with virtual rigid and soft objects. This interaction includes pick up, hold and drop objects. In a shared virtual world, interaction must be synchronized across all the participants. In this thesis, we propose a soft mesh deformation algorithm suitable for Virtual Reality interaction and synchronization in shared virtual worlds. Our particle-based soft body algorithm provides easy control of the particles as physical objects in which direct interaction can be applied. Our system is capable to simulate interaction and soft particles deformation in shared virtual worlds by using a server/client architecture.
