Three-Dimensional Flame Real-Time Rendering Based on Physical Model

Flame and other irregular objects in computer graphics simulation in recent years become a research hotspot.Flame generated by traditional techniques based on particle and texture,do not give a true picture of the movement of objects,the flame generated is random and blunt.In order to solve the problem which is difficult to realize real-time and realistic problems in flame simulation process,it adopts the flame real-time rendering method based on a physical model,the finite difference method is used for solving the Navier-Stokes equation,solving process using a Lagrange method for solving advection,combined with implicit iterative method for solving diffusion equation,using GPU powerful parallel computation ability on solving process,using ray casting algorithm rendering flame,at last,generating the realistic flame images.The experimental results show that the method is simple,rendering is fast and the process of the generation of rendering is true.
