Thread with fire demos for students
There are a lot of ways to stylize fire. You can simplify it with rising masses, you can track holes and edges
#2dfx #animation
The fire is rising because the hot particles and gas is lighter than air, this also creates air current that is pretty turbulent for bigger flames or if there's wind/lots of other stuff.
In closed room without wind a candle would be pretty static and won't move much. The smoke from it will rise pretty straight too and may start to curl quite far from the source. If you add wind you'll get the roll, flicker or more chaotic motion.
