Author Topic: Pixel shader effects for FS2_open (DL) (Read 20085 times)

I think it's only a matter of time. But you're right we cannot get any too complex effects from this. It's only a postfilter.

But we could try something less complicated, like simple blur on only red (shivans

) parts of the screen. Just to achive a slight bloom effect.

If it was possible yo get a bloom on only the pure red, pure blue, and pure green colors, for glowmaps, it might be nice.

Here is an FS2_open optimized HDRish postfilter.

It's 100% working. Though it's not not perfect, it's far better for FS2 than the original effect.

It's definitively the best HDRish i 've got.

Here some Comparaison :
With your HDRish :

Without the HDR :

But, unfortunately, i still have Fs2 crashes. I think Fs2_open hate my OpenGL systems

Nope. It looks all weird and shimmery, and the blur seems to be mostly horizontal.

DaBrain · **Reply #85 on:** January 07, 2005, 05:03:02 pm

You're right about the horizontal thing. I'm not sure why it is that way. I'm sure I did all changes to the X and Y Gaussian the same way.

But I like it. It looks pretty cool IMO.

DaBrain · **Reply #86 on:** January 07, 2005, 06:54:11 pm

This one will give you a slightly different effect. (Not very much different.)

It's supposed to detect dark pixels and to exclude them from the blooming.
For now the effect is very weak, but I think it works already.

Anyway, you can take some pss code from the Ghost.pss (from pssEffect.zip) and include the blur effect into the HDRish.pss.
The blur effect from the Ghost is perfect but they are too many that you can't play OpenGL game anylonger.

Unknown Target · **Reply #88 on:** January 07, 2005, 08:12:26 pm

This is for Radeon cards only, right?

Is there any way you can set it so that it shows up only for things of a certain brightness?

If this didn't only work on the Horizontal, it'd be great (except for the way it pulls the regular hull colors to the sides, too, but that can't be helped)

FireCrack · **Reply #90 on:** January 08, 2005, 03:27:29 am

this doesnt work with 4.4's does it?

MetalDestroyer · **Reply #91 on:** January 08, 2005, 05:28:29 am

Try this, I add the Motion Blur from the Ghost file into one of the Dabrain HDRish. You can see how the motion blur reacts.
You got blur when you move your ship on any direction and when you use Afterburner. In other case like Flying right ahead the blur disapear.

Good idea.

So it only blurs in motion? I think that's a nice effect.

It looks a bit too blured on the shot, but I think it looks better in-game.

I'll try to get my hands on a Radeon notebook again.

MetalDestroyer · **Reply #93 on:** January 08, 2005, 05:56:39 am

No, it's totally too blured in games, the same as the shot

So, i try to reduce this effect in the ghostPixelShader, I think.

MetalDestroyer · **Reply #94 on:** January 08, 2005, 06:35:33 am

I change a minor parameters, now the screen are less blur than the original.

Take a look :
Before :

After :

I change those values :

Quote

PARAM curFrameFactor = {0.4, 0.4, 0.4, 0.0};
PARAM ghostFactor = {0.6, 0.6, 0.6, 0.0};

More the value in GhostFactor increase and more the screen will flashy and blured.
But if you increase the curFrameFactor, the blur effect isn't quite exagerated. But, if the ghostFactor value is too low, the game would be very dark.

It is what i saw during test.

Add this code at the end of the HDRish.pss file.
Or if you would only test the Blur effect make a new file a past this code :

Code: [Select]


shader ghostPixelShader = 
"!!ARBfp1.0

# Increasing the ghostFactor will increase the severity of this effect.
# To keep things the same brightness curFrameFactor and ghostFactor should 
# add up to 1.

PARAM curFrameFactor = {0.4, 0.4, 0.4, 0.0};
PARAM ghostFactor = {0.6, 0.6, 0.6, 0.0};
TEMP thisFramesPixel;
TEMP lastFramesPixel;
OUTPUT oColor = result.color;

TEX thisFramesPixel, fragment.texcoord[0], texture[0], 2D;
TEX lastFramesPixel, fragment.texcoord[0], texture[1], 2D;

MUL thisFramesPixel, thisFramesPixel, curFrameFactor;
MAD oColor, lastFramesPixel, ghostFactor, thisFramesPixel;
END";

shader copyPixelShader = 
"!!ARBfp1.0
OUTPUT oColor = result.color;
TEMP pixel;
TEX pixel, fragment.texcoord[0], texture[0], 2D;
MOV oColor, pixel;
END";

surface temp = allocsurf(width, height);

texture[0].source = backbuffer;
texture[1].source = temp;

destination temp;
apply ghostPixelShader;


texture[0].source = temp;
destination backbuffer;
apply copyPixelShader;

Interesting pics of TBP EMW mission 5...

or just render glow and shine seperatly then do the blur on them.

Tell me how to do that with a post-filter, and I'll do it.

FireCrack · **Reply #99 on:** January 08, 2005, 03:24:37 pm

I was talking about when the real thing was implememnted, that yu were continuingg on from your previous post.

Evidently confusion was sewn like grain in a cornfield.
