No / Physics simulation is an active research topic in games, because without realistic physics, even the most beautiful game feels static and lifeless. Although cloth simulation is not new in computer graphics, high level of details of cloth in video games is rare and mostly coarse due to complex and nonlinear physical properties of cloth, which requires substantial computing power necessary to simulate it in real-time. This paper presents a robust and scalable real-time cloth simulation framework by exploring a variety of modern simulation techniques to produce realistic cloth simulation for games. The framework integrates with OpenCL GPGPU library to leverage parallelism. The final result is an API for games development with enriched interactive environments.

Research has been carried out in the study of cloth modelling over many decades. The more recent arrival of computers however has meant that the necessary complex calculations can be performed quicker and that visual display of the results is more realistic than for the earlier models. Today's textile and garment designers are happy to use the latest two dimensional design and display technology to create designs and experiment with patterns and colours. The computer is seen as an additional tool that performs some of the more tedious jobs such as re-drawing, re-colouring and pattern sizing. Designers have the ability and experience to visualise their ideas without the need for photo reality. However the real garment must be created when promoting these ideas to potential customers. Three dimensional computer visualisation of a garment can remove the need to create the garment until after the customer has placed an order. As well as reducing costs in the fashion industry, realistic three dimensional cloth animation has benefits for the computer games and film industries. This thesis describes the development of a realistic cloth drape model. The system uses the Finite Element Method for the draping equations and graphics routines to enhance the visual display. During the research the problem of collision detection and response involving dynamic models has been tackled and a unique collision detection method has been developed. This method has proved very accurate in the simulation of cloth drape over a body model and is also described in the thesis. Three dimensional design and display are seen as the next logical steps to current two dimensional practices in the textiles industry. This thesis outlines current and previous cloth modelling studies carried out by other research groups. It goes on to provide a full description of the drape method that has been developed during this research period.
