Fire in the glass bottle

Recommended Posts

Hello.

Is there any specific algorithms about, how could be implemented such effect(fire in the glass bottle)? Is fire in this case a particle system or does it suppose to be rendered on the plane and rotated afterwards?

Thank you beforehand for your answers.

Fire could be whatever you want.

It could be a 2D animated texture. It could be a collection of animated textures. It could be a particle system where particles bounce off the walls. It could be a[url="http://www.youtube.com/watch?v=yYkz-bdlEUA"] fluid dynamics simulation done in shaders[/url].

What do you want it to be? Edited by frob

Thank you for your answer. I didn't know that everything works. Nice to know. I, guess, I'll use a particle system in this case, since the scene itself is a very small and doesn't require a lot of computations on the GPU side.

If there are no flames, as fire is impossible in a bottle, you could use a volumetric lighting effect inside the bottle, and have the intensity flicker, at a certain point in a cone or circular diamond shape. For that to look good, the glass would have to be somewhat dirty or foggy, however.
