Abstract
Animation and simulation of crowds finds applications in many areas, including entertainment( e,g., animation of large numbers of people of movies and games), creation of immersive virtual environments, and evaluation of crowd management techniques (for instance, simulation of the flow of people leaving a football stadium after a match).In order to have a persuasive application using crowds in virtual environments, various aspects of the simulation have to be addressed, including behavioral animation, environment modelling, and crowd rendering. Real-time graphics systems are required to render millions of polygons to the screen per second. Real-time computer animated graphics has a very heavy reliance of the current generation of graphics hardware. However like many fields in computing science, the requirements of computer graphics software far outstrips hardware capabilities.
Procedural generation techniques are widely used in computer graphics to model systems of high complexity. Many of these techniques target the generation of natural phenomena in high complexity and detail to achieve realistic results. Procedural generation can be computationally intensive and is not commonly used in real-time systems to generate entire virtual worlds. However, advancements in processing speed and graphics hardware generate three-dimensional models in real-time on commodity hardware.Applications can range from entertainment to urban design or crisis management, traffic simulation in big cities can benefit from this visualization techniques.
