A Mass-spring Model for Real Time Deformable Solids

This paper presents a mass-spring model for real-time simulation of volume preserving deformable solids. A new type of springs that show collective behaviour was developed called "support springs", which model the "matter" inside the object and make it preserve its volume without the need of explicit volume computations during the simulation as it is done in conventional methods. Comparing the volume during simulation with the initial volume of the deformable solid demonstrates the accuracy of our approach. Experiments on different geometry show the low computational complexity, which is linear to the number of triangles of the deformable solid. Interactions between supportive clothing and a deformable female upper torso are shown in a simulation at the end of the paper.
