Real-time Representatioin of Destruction Process Considering Interaction between Two Virtual Objects

Abstract

Virtual objects have been synthesized based on physical phenomena using various kinds of techniques in artificial reality. In most cases, the calculation decreases owing to some kinds of simplified models and/or reduction of their composing elements, by which their drawing of shapes is easily performed in a higher speed. However, the deformation of virtual objects beyond their elastic limit has not been conventionally considered. Thus, it is necessary to take into account plasticity as well as elasticity and viscosity for more accurate representation of dynamical deformation process of materials, for which a new coefficient for positional relation of masses is proposed to represent the various dynamical action of the objects. That is, their interaction is mathematically formulated to simulate their actual action and reaction on the basis of their physical relation. Thus, a virtual object of elasto-visco-plastic model can be applied for the real-time dynamical presentation of the deformation and destruction such as “Crack”, “Collapse” and “Smash”.
