Shader Idea

It doesn't seem much different than Glow Total, and I still can't recreate what Nifflas did.

EDIT: And it doesn't allow multiple objects to bloom together.

Bloom2D exactly do what Nifflas described.

Currently the objects can't bloom the other objects if the shader is applied to them because currently MMF2 don't allow to get the background pixel. but you can apply this shader to a layer and all the objects will bloom each other.

In a multi-layer application, it would be nice with the option to apply an shader over everything (the mixed output of all layers).

I tried everything and couldn't make it look real.
What values did you use?

[Werbad]

Did you apply it to the Layer or the Objects?

As Nifflas said, it could be nice to be able to apply a shader to the whole screen (all layers).

[Nifflas]

Yeah, this effect would make most purpose if that was possible (or alternatively if my application used one layer only).

I think you should look at my last PixelShaders pack (Complex-shaders pack v2) and try using the effect called "Glow total". It's exactly what it does.

I've not called it "bloom" because a real bloom effect take in account the specular and diffuse lights of the 3D environnement thanks to a vertex shader associated to the pixel shader. Here we are in a 2D environnement, so a real bloom effect is not possible.

I think if you consider where the term bloom comes from though, which I'm assuming comes from people claiming, flower buds bloom off of a center. Light blooms off a center. So I think the term "bloom" is still appropriate. Just make it clear that the bloom effect is much more complex in a 3D environment, then in a 2D environment, because there are more variables to take into consideration.

It's like asking to make a 3D world with a 2D engine. It's not really possible but you can create something similar.

That's why I've updated the pack with the "bloom2D" FX.
