Hi all ,



I have a simple particle systems class to work with , tied with a simple shader which is able to render point sprites.



Firstly what I am looking for is implementing fire , And hopefully after getting it done , I want to make it look like as it is 3D or at least create an illusion

My target is implementing a fire like the one in the video :


I would greatly appreciate any help for this.

Any tips ?



I have heard of Perlin Noise but coud not figure out how it works and how it makes 2d sprite based shaded particle system look volumetric



Any help would be great

Is there anyonw who dealed with this ?

Also I do have another question for this topic.


Currently I render an animated fire , by rendering a simple quad and animating the textures.


Could also that kind of "particle system" made to look 3D ?

It can be made rather easy with a simple "billboard" particle effect.

The billboard particle effect has to consist of several particles in order to make a nice effect.

This picture can maybe inspire you how to create it :)

To be completely honest, the video you provided does not show much of the fire. It looks completely particle-system driven to me. If the fire has no interactions, then it will be possible to animate the various sprites using vertex shaders only, which is very fast and has widespread compatibility.
Interactions will involve more complex management... but I'm not going to elaborate on that.

I've seen it being done by having multiple quads rotated around the center. I'm not really on it but it was a acceptable solution in 2002 so you can indeed get some mileage out of the technique.
