Flame Simulation Based On Improved Particle System

There were three methods for flame simulation in computer graphics:particle system method, mathematic and physics-based method and the method of texture technique. In this paper, we improved the core of control mechanisms of the particle system, to a certain extent. We ameliorated the traditional methods to overcome the excessive randomness. Mathematical methods,physical methods and texture technical were used in our work.In Chapter 1,we mainly Introduced the background of our work. We classified flame simulation methods reasonably; earlier models of the flame simulating and the latest developments in this field were discussed detailed. We bring out our train of thought based on the accomplishments of these issues on recent years.Chapter 2 briefly introduced the method adopted by the overall management system: particle system. We managed its basic framework reasonably, and then a number of improvements on the core of control mechanisms were put, so that it can adapt to the rapid development of the times.In Chapter 3,we controlled the changes of particles of the flame used the reference of center line, we called that particle chains. The control process of this method is relatively simple. We considered that flame is a special fluid, and thus we done calculations based on the Lattice-Boltamann method. Some researches were presented of the preliminary results of the control mechanism, and some results have being achieved.Chapter 4 presented a fast flame simulation method based on the texture slice on the basis of the particle system,and compared with the new research results which come from the application methods in recent years. It used suitable texture slices and less transparency,to rendered the flame procedure by a rotation loop.The analysis showed that the texture slice method had some advantages not only in many ways but also in lot of application fields.Chapter 5 is the future direction of the study and the conclusions, we analyzed three important techniques briefly, included flames details, the control mechanisms and the simulation speed of result, and some studies of the future researches of this direction are presented.
