使用 SPH 粒子模拟火灾
我想使用 SPH 粒子模拟火焰。我了解 SPH 背后的概念,但还不了解如何将火建模为流体。
- 我是否必须向粒子添加一些温度属性才能从中导出颜色?
- 我是否必须考虑周围的空气颗粒才能产生浮力效果?
- 粒子从哪里获取热量?我是否必须在某些空间上添加一个热发射器来产生温暖的粒子,以便温度随着时间的推移扩散到其他粒子?
- 有一些教程可以描述我的问题吗?
I want to simulate fire using SPH particles. I understand the concept behind SPH but don't understand yet how to model the fire as a fluid.
- Do I have to add some temperature property to my particles from which I can derive there color?
- Do I have to take the surrounding air particles in account to create some buoyancy effect?
- Where do the particles get their heat from? Do I have to add a heat emitter over some space which creates warm particles so that the temperature then diffuses to the other particles over time?
- Are there some tutorials which describe my problem?
