Author Topic: Pixel shader effects for FS2_open (DL) (Read 20070 times)

Well, this is only for the ATI user (which doesn't include me

):

The Radeon 9xxx cards have (driver) feature that allows to use postfilter PS effects. Probably nothing new to you.
It was never really important, as the standard effects were boring.

But I just found a nice bloom effect called HDRish. (It's no real HDR!)

Here is everything you need to know:
http://rage3d.com/board/showthread.php?t=33787285&page=1&pp=30

Just dl 'pssControl2.zip' and 'entries.zip' from this site:
http://www.beyond3d.com/downloads/smartshader/

Use HDRish and play OpenGL FS2_open.

If you choose to test this, drop some screens here.
I'd like to know how it looks like.

Hmm. I'll try this out right now. Hold on.

Taristin · **Reply #2 on:** January 06, 2005, 10:46:37 am

Ok, well, they are right, the effect is completely overdone. If it could be tuned down, it'd be perfect...

Here's some screenies:

aaaaah've hud a wee bit too...too...mu-mu-much tae drink.......it'sh a wee bit blurry

DaBrain · **Reply #4 on:** January 06, 2005, 11:02:15 am

Should be no problem. You can open the pss file with Nootepad.

I'm not really sure what has to be changed, as I don't know much about pixelshader.
There should be an entry called 'gaussian something'.

Try to lower some values there.

I'd edit it myself but I can't test anything.

BTW I think the menu will alway look strange.

What do I change to what?

DaBrain · **Reply #7 on:** January 06, 2005, 11:16:56 am

Well, I'm not sure. Actually I have no clue.

I think you have to change something in this part:

Edit: Forget it. I think I was wrong.

I think the clamped part is the gaussian radius, which has to be reduced.

Or try to reduce the PARAM Weight.
It sounds like it could control the intensity.

I'll ask someone who should know what has to be changed.

Maybe try changing the divisor of

Code: [Select]

surface blur0 = allocsurf(width/4, height/4);
surface blur1 = allocsurf(width/4, height/4);

(?)

I don't really have a clue myself; try http://www.driverheaven.net/dhinterviews/smartshader/ maybe (search for allocsurf)

I think it creates a copy of the image being rendered, and downsizes, and finally adds the downsized image over the top; i.e. so it's blurred by being shrunk and then overlaid. So maybe try div by 2?

EDIT; think blur0 and blur1 are used for x and y respectively. Not sure why.....

DaBrain · **Reply #10 on:** January 06, 2005, 11:24:27 am

Looks like you're right.

@Target this will indeed weaken the effect.
But I think what we want is to rise the contrast of the image befor the blooming is applied to the brightest parts.

This would cause only the really bright parts to shine.

@Raa Try to edit the file like Target suggested and try to reduce the gaussian size like aldo suggested.
Edit2: @Raa be sure to edit both the gaussianX and gaussionY filter! It's in the code two times.

Edit: This could look relly nice if it was to be implemented in the code. (As non-postfilter)
Only for shine-, glow-maps and glowpoints (suns, thrusters).

Doing that eliminated the effect.

Just got an answer:

Der Filter wird durch die beiden Weight Felder gesteuert. IIRC sind die Werte dabei vom Zentrum zu Rand gespeichert. Um den Effekt abzuschwächen muss man die Werte im Zentrum erhöhen und die am Rand verringern. Die Gesamtsumme muss aber gleich bleiben.

[crappy_translation]
The filter intensity is controlled by the 'weight' fields.
IIRC the values are saved from the center to the edge.
To weaken the effect you have to increase the values in the center and reduce the values for the edge. But the total sum has to stay the same.
[/crappy_translation]

That would mean the left value is the center.

Code: [Select]

PARAM Weight[3]=
{
 {[i][b] 0.182008[/b][/i], 0.116053, 0.073999, 0.047184 },
 { 0.030086, 0.019183, 0.012232, 0.007799 },
 { 0.004973, 0.003171, 0.002022, 0.001289 }
};

Only for shine-, glow-maps and glowpoints (suns, thrusters).

If I'm understanding it right, it works in a similar-ish way to what Sticks was implementing with the 'overburn' effect... I think he (at least initially) was copying the z-buffer image, shrinking it, and then overlaying an less opaque version.

Now the ATI users have pixelshader effects and the nVidia users have env- and shinemapping, what an unfair world.

DaBrain · **Reply #17 on:** January 06, 2005, 11:59:58 am

I don't know about that.

But I saw the pic. And it looked like that.

@Overlord ATI user will have env maps too, soon.
And Nvida user will be able to use postfilter PS with an upcomming program called DX Tweaker. Which will btw enable real HDR for all games.

Actually, now I have all of them!
