particle based fire effect wrapping the flames around a mesh

thespecial1 · Post by **thespecial1** » Tue Feb 10, 2009 9:45 am

hey guys

i have been messing around with particle effects for a coupla months, basically i am trying to make to decent fire effect that sets a mesh on fire. the mesh is some 3d text, and i am really struggling to make a fire effect that looks decent.

I have encoded the various examples in the forums, including the one in the irrlicht examples but no matter what/which i do i am never impressed even slightly with the results.

so has anyone managed to make relativly realistic looking fire (pref using particles) that would impress, a little bit of example source would be most appreciated as this is starting to get me down

thanks
Rob

fire can be animated billboards with good blend modes. This will make cool looking fire (as i dont think particles will ever look nice)

Shaders are the other option, and that option is the best.

yeah particles probably won't ever look that good for fire as fire isn't really a particle based thing...

Have you looked at this shader?

i tried it a while ago but was getting compile issues, hold on I'll give it another try, cant remember what my issue was. back in a sec.

ok just re inserted it and i get a mass of compile issues at run time with the shader, like this

so i have yet to see any shader in action, any others lurking about??

thanks Rob

or is their something extra like an open gl include that i would not normally need or somit .. hmmmmmmmmmmmmmmmmmm

thespecial1 · Post by **thespecial1** » Tue Feb 10, 2009 1:20 pm

on shaders, do they have to be converted for use with irrlicht or will many work without much re working ;0)

thespecial1 · Post by **thespecial1** » Tue Feb 10, 2009 1:35 pm

after more searching, i take it i need to include the Xeffects SDK in my project to get this to work ;0)

thespecial1 · Post by **thespecial1** » Tue Feb 10, 2009 1:44 pm

not sure on the truth of the last statement, can't find any reference to "Xeffects SDK" other than a coupla forum posts, google turns up nothing, if is this what i need then where do i find it anyone

JP · Post by JP » Tue Feb 10, 2009 1:44 pm

I wonder if those compile errors are something to do with using DX shaders with OGL? Try using DX9 as the driver.

Irrlicht supports a few shader types, basically anything that works with DX/OGL should work fine... If you want to use Cg shaders then you can look into irrCg for support.

You don't need XEffects to get this shader working though.

and dont post 1000 times in a row, edit the post that was last made (if its the last post) at least wait for a reply before spamming your thread...

and the problem is as mentioned, using the wrong device type

thespecial1 · Post by **thespecial1** » Tue Feb 10, 2009 2:03 pm

for anyone else who is looking Xeffects can be found at

http://irrlichtirc.g0dsoft.com/BlindSide/XEffectsR.zip

from this post http://irrlicht.sourceforge.net/phpBB2/ ... t=xeffects

ok i have switched to direct3d 8 and i get

Code: Select all

Irrlicht Engine version 1.5

MySQL Version: 5.1.30-community
Finding the Murmuur Database on the Server Specified..
High level shader materials not available (yet) in this driver, sorry

and on direct3d 9 i get no errors whatsoever, but unfortunatly i need shaders that work with opengl as i am developing a gl media font end that runs on mac, win and linux

I'll have a play around with xeffects and see what it can do

i found a sweet demo of water (absolutly sport on and fire shaders (the fire is not quite top notch) on

it only has docs on the water thou

Feel free to take a look at my particle system affectors if you need more control over particles. The changes to the Irrlicht source aren't needed anymore, but the affectors should still work with 1.5. A simple search in project announcements should bring it up.

It also includes a flame thrower demo that you can take a look at.
