摘要: 提出一个通用的火焰模拟框架,通过前处理、火焰模拟和后处理三个阶段生成满足用户需求且真实感强的火焰动画。针对该模拟框架,给出一种有效解决方案。根据火焰的两相流特性以及流体湍流特性,提出火焰的湍流模型,在有限计算资源条件下生成细节丰富的高真实感火焰动画。实验结果表明,所提出的火焰模拟框架切实可行,能逼真模拟基本火焰现象以及在复杂曲线、曲面和蔓延规则约束下的火焰动画。

Abstract: The realistic and controllable fire animation has been widely used in many fields, such as film-making, entertainment, fire protection, and so on. This paper presents a general flame simulation frame, which includes three phases: pre-processing, fire simulation and post-processing. In this way, the realistic fire effects that user needs can be generated. In order to implement this fire animation frame, the corresponding solutions is provided to address the key problems in every phase. According to the two-phase flow characteristics of fire and the performance of turbulence fluid, a turbulence model is proposed for fire to rich the flame details using the limited computing resources. The experimental results show that the effectiveness of our provided flame simulation frame, which can not only generates the basic fire phenomena but also other fire animations under the control of complex curves or surfaces and spreading rules.

Key words: fire animation, flame simulation frame, turbulence model
