Abstract:

The simulation of irregular objects is the one of the most difficult and attractive problems in computer graphics. The simulation of fire is of a great challenge because of the variability of the shape of fire in time and space. This paper discusses the variation of the attributes of fire particles and the choice of texture slices in detail.Particle system is the most effective method for fire simulation,which uses a texture map technique to enhance the rendering quality, decrease the number of particles and accelerate the rendering affectivity. Examples show that the method meets the requirements of realtimeness and reality.

Key words: particle system;simulation of fire;texture map;rendering
