Mass-Spring-Based Three-Dimentional Cloth Simulation System

Three-Dimentional(3D) Computer Graphcis Simulation Technology is widely used inthe fields of engineering, virtual reality, special movie effect making and video game making.As an important part of 3D Computer Graphics Simulation, 3D Cloth Simulation, espe-cially real-time 3D Cloth Simulation is very useful in real-environment simulation, human-computer interface and virtual reality. It is able to enhance the visual effects of apparels,?ags, banner, curtain, table cloth under external forces like wearing, hanging and blow-ing. Among these algorithms, physical-based cloth simulation algorithm which models the apiece of cloth as a mesh of masses and springs, could achieve more vivid visual effects thanothers by calculating the inter forces on masses and springs with physical laws. In this paper,the implicit integration is proved to be the most suitable algorithm and also present effectiveC++ code implementation.However, due to the inherent large time-step in real-time simulation, the cloth maybehave super-elastic effect. This paper propose a possible solution of Mass Position Modifi-cation Altered(PMA). This new algorithm eliminates the modification nihilation effect, Thusenhanced the modification effects.This article illustrate the design and implementation of a cloth simulation experimentalplatform, which is continuously developed when I was working on the algorithm develop-ment, applying the software engineering thoughts, and make a software platform on C++. Avariety of algorithms are able to be tested and benchmarked on this platform. With a lot ofdesign trade-offs to balance the performance and extensibility, It developed into a handy andpowerful platform for developing and testing cloth simulation algorithms.
