So you mean this neon-effect?

Well the purpose of bloom is: Bright parts bleed over dark parts.
And that's exactly what my shader does an what's beeing done in the screenshots you've posted (except the 1st one, I think this are simple 2d textures).

Let's take the last screen as example. ( love that game btw. )
To get that effect simply use sprites and add a bloom shader with very low threshold.
That's all.
You probably need 3 Bloom passes to get that radius with a good quality but in theory that's all you have to do.

edit: as you can see it's possible (and easy)

I took the bloom shader and turned down the threshold.
( and I discovered that using pow on the alpha causes early bleeding which is perfect for a neon-effect )

Well good , so another bit of code you could share some time ?
(i talk about that bloom shader!)

Sharing the shaders?
Well... the shader(s) you're seeing above are custom made for you, so, yes I think I'll share them with you

Potato-Man@ so as I see, you are ignoring my post above.. very nice of you carry on

So, at the moment the shaders still need some work, especially making them more userfriendly is important.
I think I'll finish this tomorrow.

Until then, some more screens

EDIT: @3run, I didn't ignore you
...and that I said I'll share the shaders with ratchet I didn't mean I'll only share them with him, sorry if you misunderstood this.
If I'm finished I'll create a new thread so everyone who's interested can use it

Amazing results

Here is simple test i made (the scratches have been part of alpha by inadvertance :()


But i can begin the game now.

Iµ think this shader will help making graphic eye candy stuff with simple bitmaps or models.


I tried to put all code inside my main level code, but it bugs ?
Strange i put effect file, and the code of your main in some action ??

It seems my main don't see the effect file perhaps ? Straneg they are in same folder and my main have the import line ?

Okay, I'll do some improvements in the next days but the shaders can already be used now.

About the blur and the glow shader in general:
these shaders support HDRR, so you're not limited to the color range of 0 - 255. Use bright glow-colors to get a nice, bloomy effect.

Regarding the demo:
I've made 2 demos.
One showing the glow effect with the 2 cubes and one showing a neon-style effect (with graphics from the game 'GridWars')

have a look at 'main_cubes.c'.
In this file there's a lot of stuff explained and commented.

In the demos you can enable / disable the postprocessing with the p-key, move with wasd & mouse (hold right mouse
button to rotate the camera), use the zoom-blur effect by holding enter, and toggle the cubes rotation with the space-key.

EDIT: regarding your problem: it seems like the object is not using the shader.
Make sure you set the right material and .fx file
EDIT#2: in the example you uploaded the object-shader's file was called "glow.fx" or something like that. I chaged the name to "object.fx" maybe that's the problem

I'll recheck my project.
Awesome work, a new 3DGS usefull shader is now possible.

thanks
looking forward to see some screens ( and gameplay, of course )

Few suggestions man:
* radial blur, should be able to find the center of the screen it's self (if we change during the run-time resolution, there is an offset).
* same for the HDRR I guess, cause I have a black line at the bottom of the screen, if I change the resolution, maybe I need to reload effects?

I use AMD, you maybe going to hate me for that Otherways, it looks really professional man! Could I ask you to add one simple post shader to the HDRR via PM (I need it for my current horror project)?
