source code of shader

[skumar]

Hi,
On which source code file i can get the source of the Lightmapping shader?
I am not good at source mining but i really need that for study...
Any helps appreciated...

thanks in advance...

I don't think you need a shader for this technique of lighting since lights are baked into textures (?)

PS. Why do you put "..." after most of your sentences?

@skumar: AFAIK Irrlicht is not using a shader for the lightmap materials. It`s using some blend states for this, as its extremely easy. But, in a shader you`ll simply need a color sampler texture and a lightmap sampler texture, usually 2 texturecoordinate sets, which you pass from the vertex to the pixel shader and you do:

Code: Select all

float4 finalColor = sampledTextureColor * sampledLightMapColor;
return finalColor; 

Can`t be easier than that. Well, some extremely basic shader knowledge is needed though.

He does this because recently there`s a shortage of "."-s in the forum because of this guy, who never puts single periods in his posts: http://irrlicht.sourceforge.net/forum/v ... =1&t=44772

Oh, That makes sense now

Thank you shadowslair and all others for helping me....
serengeor.... i put a lot of dots simply to show the flow rather than a stop...
like when we speak....

everything in the life is flowing...why dont that happen when you write also....

I was taught otherwise at school.
