Aiming at the key problems of the realism and real-time simulation of the classical particle system flame, a new flame drawing algorithm based on the particle system is given, the initialization of the particle attribute is determined by the emitter, and the update of the color, position, lifetime and other attributes of the particle is optimized, the movement change of the particle is controlled by the low pressure point, the particle is represented by the four-corner patch, combined with the texture mapping technology for three-dimensional flame rendering, and the texture adopts time-divided mapping to simulate the burning process of the flame. Experiments show that the algorithm simulates the movement and appearance of the flame, and real-time drawing speed can be obtained by using the standard graphics system on ordinary PC platforms.
