Raydium is about to provide a support for GLSL (OpenGL Shading Language), and this screen is the first test of this new experimental feature, with a "toon shader". More to come ;)

Ok, it's getting better. Another try with a normal map shader, this time:

Yeah, were're now able to get the same awful shiny plastic rendering that all other engines provides ! ;) (It's hard to get the right effect with normal maps).

I'm now trying to find the correct way to add shader system to Raydium (per object ? per texture ? per frame ?), after what I'll wrote a small demo and port the whole thing to win32 (It can be hard since there's some important changes in core, as Raydium now use another new dependecy: GLEW)

i suppose the best way to add shaders to raydium is per texture.
Using per texture shaders we get s simplest tri file and enought flesibility to let the artist model anobjecto with areas with a few shaders or even without shaders, at their own.

However....

i'd like a shader support for frame, cause id like to apply some effects to the fullscreen in certain moments during the game. I mean an ultra-saturated mode, a desaturated mode, a black and white mode, a cartoon mode, and it also can be used to speed up HDR and implement nice motion blur effects...

So...

I think we have to make a basic independent implementation, and then a few functions related to each possible use

Ok, after a few problems it's now possible to attach a shader to a texture. I will stop here for now :)

I'm searching for a "good" free normal mapped model ... If you've found such model, tell me where !

Ok, I only need to clean a few things, upload data, and the shader support will join the SVN :)
A quick screenshot of the demo app, using two distinct shaders :

Ok, shader support is now available ! (since rev 334) Have fun ;)
It needs a few things again, like an assert at the begining of each function to return if hardware shader support's not available (it probably crash, now)

Shaders are not a magical option :) You need a new shader for each effect, and sometimes new data. That's the case for the normal map in this demo :

Texture (aka Color Map):

and its normal map:

The shader demo now features a new FX : parallax mapping.

Small Raydium screenshot (it looks way better when it moves ! :) )

Look at the ground... this is in facts a perfectly flat triangle, but ground "displacement" gives relief effect (and changes with point of vue !).

I'll try to create better data (model and color/displacement/normal maps) to make this demo more attractive ;)

Superbe :D

Par contre j'ai fait un svn update et lorsque je veux compiler le test, j'obtiens :
Code:
~/code/raydium$ ./ocomp.sh shader_test.c
rm: ne peut enlever `test': Aucun fichier ou répertoire de ce type
In file included from raydium/index.c:56,
                 from shader_test.c:7:
raydium/render.c: Dans la fonction «raydium_rendering_from_to» :
raydium/render.c:337: erreur: «raydium_shader_support» undeclared (first use in this function)
raydium/render.c:337: erreur: (Chaque identificateur non déclaré est rapporté une seule fois
raydium/render.c:337: erreur: pour chaque fonction dans laquelle il apparaît.)

raydium/render.c:338: erreur: «raydium_shader_shaders» undeclared (first use in this function)
./ocomp.sh: line 14: ./test: Aucun fichier ou répertoire de ce type
:oops:
