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 fluid dynamics simulation done in shaders.

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.

Thank you for your answer. Interesting idea.
