Nadro · Post by **Nadro** » Thu Jun 21, 2007 10:12 pm

Hi:) I start work on special shaders pack (in this time only opengl) "Chernobyl Shaders" for Irrlicht. I have add this shader:

Plastic in GLSL and HLSL - Done
Glittering - Done
Dust - In work...
Per-Pixel Point Light - Done
Per-Pixel Spot Light - In work...
Per-Pixel Point Directional Light - In work...
Shadow Volume - In work...
Shadow Mapping - In work...
Soft Shadow - In work...
Fur - In work...
Motion Blur - In work...
Glass - In work...
Fire - In work...
HDR - In work...
Eroded - Done
Depth of Field - In work...
NormalMapping - In work...
MultiPass (for mix effect from all shaders:)) - Done
Multi Light above 8 - Done

TechDemo smilar to Unified lighting and Shadowing from Doom 3
All shaders use Pixel Shader 1.1 and sometimes 2.0

too bad my crap does not support pixel shaders..

anyway great project, maybe screens?

Oh yes, screenshots would definitely make this post more worth. And a link of course

Yes links and screenshots!

I really need to update my hardware. No shader support atm unfortunatly, pisses me off.

OK I add archive with 3 effects (all based on example from render monkey. I can't add all Lighting in binary because I don't clean compilation, so I add application with point light tomorrow, but now I can add screen:)

PS. (~5 projects I have from ATI Render Monkey (onle the best, usefull in Irrlicht Engine), but all others shaders eg Light with Multipass etc. are shaders design by Me

)

This is 3 examples:

And this is screen with multi pass using point light:

with Plastic:

with Glittering:

with Eroded:

On this day it's all:)

wow.
Nice.

I just started to dream about -- ones Irrlicht will have a collection of standard (embedded into engine (like fonts)) shaders.

Very nice.

Im wondering how possible would it be to animate the errosion?

Nooooooo! The examples won't work for me, console says I don't have a good enough version of openGL....I blame you Windows Vista

since you work with rendermonkey and mostly the default set ( glitter and all), could you at the same time provide the DirectX ones too please? They are a little bit more + that way Irrlicht is that much more compatible

The examples don't work for me. It says "could not be open mesh ../data/mesh/elephant.obj" and in fact this file is not in the .rar

you rocks!

Sorry I forgot add "data" to archive. I updeted link in my second post, now examples work

Of course I like OpenGL and DirectX, so I write all this shaders also in DirectX

At night I add example with lights:)

I done multi lighting using 5 passes (4 calculation on 1 pass). Of course Lighting shader is Alpha version and on this time is slow

In demo You Can see 13 per pixel point light (I select red circles 9 lights on the screen) and lighting room and two dwarfs. You can download demo from:

I'm waiting for comments:)

Hey since you are good at GLSL can you convert my shadow mapping shaders from HLSL to GLSL please? I will release my own shader pack very soon in HLSL so we can work together to provide solutions for both drivers.

PS: Irrlicht already has Shadow Volumes thats what stencil shadows are...But maybe it is faster in a shader?

Nadro · Post by **Nadro** » Wed Jun 27, 2007 11:46 am

OK

I can convert Your shader:) Yes, Irrlicht stencil shadows are very slow, so I write shadow volume in GLSL shader because will be very faster:) and Irrlicht shadow has got artefact in my Radeon 9550, because node from put shadow have this shadow on Your mesh :/ I planned create shadow similar to stencil shadow volumes from Doom 3:) Yes we must add shader support for both drivers:)
