Material Bloom ?


Recommended Posts

Hello ,I have a question about a picture and its shader.I played a game and saw (in other games too,but here it looks very nice) that the edges of a model which are directed to the sun have a kind of bloom.

The problem is,that leadwerks bloom can't work only for a few models in a scene,for example weapons and in the picture the material isn't very fair,so it wouldn't work ,because you need fair materials to bet a shine effect.



I mean something like that(scroll down for pics) : http://www.ogre3d.or...wiki/Faking+HDR


Have somebody made a shader with specular bloom??

When not can somebody tell me how to make that(only the idea)

Leadwerks already put lighting result in the bloom buffer, and use them in the bloom shader.

But tbh the bloom shader itself is not good.

Looks good. I might give a try at porting the OGRE example.

One question.As this effect has (I think 8) passes I have to save the stages in buffers/textures.But how to do that?




//Now I want to get the output of the shader,because the shader have a 2D sampler for input and now I need the output written in the //RTBloom buffer
DrawTexture(GetColorBuffer(gbuffer)....); //???? maybe so?



So I made it as explained at the top.

But in the last shader I have to put the normnal rendered colorbuffer and the other 4 buffers(blured).So I bind the buffers with BindTexture to the shader ,but now I have to call DrawImage() ,but I have 5 buffers......how to do that?????

Now I made a shader which make specular areas glowing with bloom.Iam going to write a new bloom shader an upload the specular bloom and the new bloom shader.

In the pictures the specular is everywhere,so I don't use a specularmap,as you see,because the hands have specular.

A little preview:
