Realistic fire

Remco · Sun 02/05/2004 14:42:51

Im now trying for 2 days to make a realistic fire and i am still not satisfied, this is what i have now:

Could someone give me a tip or a remake how to get it better?

I would think animation would be quite important?

More reds and yellow, looks a bit like burnt grass? :o

Remco · Sun 02/05/2004 15:00:07

ofcours i am going to animate it, but i wanted to know first if the start was good or not.

Fire is very difficult, especially to animate it. (At least, for me it is).

A technique I'm currently trying is using filters in PaintShop pro. As you can see on the image below, I started with a very simple drawing of some flames. To make it more realistic, I applied some filters.

I first apply a Motion blur (angle: 45, intensity 40). After that, I applied a Gaussian blur (radius: 3).

I think my example is a bit too blurry. You should eperiment a bit with the filter settings to get a better result.

It's good that you're trying to draw it all on your own!

My suggestion is to turn up the brightness 10% and the contrast 50% (these are Photoshop settings). Basically you want to saturate the reds and yellows.

I'd also make the flames less regular in height, and more blobby towards the bottom.

Do a google image search for "fire" and you'll see some firefighting images on the first and second pages.

If you want some animated fire, the best thing might be to download one of those fractal fire demos and take screenshots. It's going to be really difficult to paint three frames of 320x240 flames and make them look good.

Good luck!

it seems a bit level, maybe adjust hight even more and make it more up and down

and put more flares on it as well

i like that edit, its a good technique to use for fire, saddly i still haven't got psp off OSC yet so i cannot do that

QuoteMore reds and yellow, looks a bit like burnt grass?

what you wanted to say was "burning grass", or?

hmm, I had a tutorial link... I'll search it and post it here when I found it.

Privateer Puddin' · Sun 02/05/2004 15:52:06

no, i said what i wanted to say. thanks.

I've edited your latest edit, again with the Motion Blur filter in PSP:

Remco · Sun 02/05/2004 17:33:06

too bad my painting program (ArtGem) does not support it.

stuh505 · Sun 02/05/2004 17:57:36

i think your best bet is to look at some photographs of campfires. i just modified yours from my head but i think i could have (or you could also) improve it a lot by looking at real fire because i dont think real fire has quite so many tongues like this. anyway here's my edit

i just used smudge

Igor · Sun 02/05/2004 17:57:43

I like Erwin's and Stuh's edit best. The problem i still see though, is that there's no real glow. To make fire really believable it must shine (give away light). Fire has usualy a bit orange glow, while the fire itself is yellow or white.

Edwin Xie · Sun 02/05/2004 19:56:14

Look, I have been playing a game that has a pretty good fire. It seems like there are more yellows than reds and the problem is, there are no skinny sections of the fires. If you shrink that fire picture you got there then add duplicates of it it would look like a realer one (you can change the sections of the fire to different sizes if you want).

Chicky · Sun 02/05/2004 20:05:49

i like the edit stuh, very cool 8) but i think there mayne a little too much red/orange. More yellow would work

Edwin Xie · Sun 02/05/2004 20:14:18

This is what I meant (smoothen the picture I have shown you)

Edwin Xie · Sun 02/05/2004 20:17:17

Oh, and please don't giving opinions about that picture, it is just an idea. 8)
(Edit: Rounden the edges too.)

Remco · Sun 02/05/2004 20:35:58

Tnx for all the comments en tips. I made an edit and i hope it is a bit better now but i am still a bit doubtfull:

stuh505 · Sun 02/05/2004 21:24:40

remco, it doesn't look like you have listened to anyone's suggestions...

here instead of trying to edit yours i started over to give an example of what i suggest:

Daz · Sun 02/05/2004 21:41:03

i think the bottom of Remco Bogaard's edit should have a lighter bottom maybe even translucent a bit like stuh's edit.

the fire keeps getting more and more realistic, i think stuh's one looks like a large scale forest fire, the way it is spread out not and looks amazingly cool.

you might want to look at opo tersers edit on his first edit http://www.agsforums.com/yabb/index.php?topic=13520.0 its a bit down from the top
