White Phosphorus Smoke Produced By Combustion Simulation

Computer graphics, with the computer and its peripheral equipment generated and developed, and as the rapid development of computer technology, how realistic simulation of the natural landscape, to become the most used area of graphics and challenging research direction, one of For the smoke, clouds, waterfalls, lightning, rain and snow, fire, flowers, trees and other natural features of the realistic simulation, in aerospace, film and television advertising, automotive, electronics, and virtual scenes, and other major areas with a wide range of applications. In many natural features in the appearance of smoke is very irregular shape, there is no smooth surface, belong to the deformation of fluid phenomena, and the law of motion affected by temperature, wind and other external factors enormous impact. Therefore, simulation of smoke has been difficult and irregular objects in a simulated hot spots.This in-depth study of the particle system simulation method of smoke, and this method is applied to the burning white phosphorus chemical testing, the smoke at home and abroad simulation algorithm has been elaborated, analysis and conclusion, and illustrates the particle system in the modeling Irregular areas of natural scenery several advantages. Secondly, the discussion of the smoke, the smoke particles from the resulting model to the demise of the property changes, including smoke particles on the shape, size, color, position, speed, life-cycle and so on. According to the spread of smoke factors in the original algorithm based on the effect of white phosphorus burn to shine,The introduction of temperature conditions on the impact of white phosphorus smoke effects generated by fine simulation. In the drawing process, through texture mapping for the system to add background image to create the image of the smoke even more to achieve human-computer interaction.Finally, using VisualC + + language programming tools, three-dimensional animated environment, OpenGL graphics library to support the design of a demonstration system to realize the algorithm, experiments show that the improved smoke simulation algorithm can be implemented on ordinary PC, the smoke generated by burning white phosphorus analog.
