Fullscreen shaders

Just wondering if anyone here knows how to make new fullscreen shaders or edit existing ones. The main thing I want to do is stuff like color switches, like the one they already have. i hope it doesnt take too much hard programming...

That shader looks so cool Der/Nalia. :D
Looks like you used some of the bumpmapping code in there...weird.

I tried that shader. I put it under fullscreen shaders, went into the game and did "setfullscreenshader test" but it didn't work. I tried it again with numbers after it (...test 1, 0, and 1000) and it was still broken. What am I doing wrong..?

Does your card support full screen shaders?

yes it looks cool ;o)

Yeah, my card supports it. I can run bloom and all the other ones it comes with. I can run bloom in some maps with a 1280 res and max settings and get 30 fps, and otherwise I get shitloads higher FPS, so I have a pretty good card (although Sauer is a resource whore, I gotta say- Farcry runs top setting high res and gets almost double that FPS...)

Yeah and Far Cry doesn't have quite the same number of advanced features that Sauerbraten has. You're comparing apples and oranges there (and anyway, its an isolated problem, because I get sub 80 FPS in Far Cry and 199+ in Sauerbraten).

Here are some more screenshots with some maps my team has done... with before and after

Oh yeah, and share your shaders (because I suck at programming- I tried it. I pretty much said "wtf" after I saw gibberish, and Sauer-script is even more gibberish)

Did you recompile the code?

I just copy and pasted it

Well, without recompiling your code ist not even in the game. ;)

Uh how do I recompile it?

urm... stdshader.cfg is read each time the game launches, there is no need to compile anything else if you're just editing it.

We shouldn't need to be editing stdshader.cfg ( or anything in the /data dir ). The proper method of adding in new shaders, is to use a map.cfg. This won't work with the fullscreen shaders, so I suppose it's the only way?

Still doesnt work -.-

it works just fine in a map.cfg

copy pase it at the end, and voila

I think the object of a full screen shader, is to not be map specific...putting it in a map file requires loading that map, and the effect will not be in any other maps.

the bump mapping is what allows the edges to be highlighted like that. there is prolly a cheaper way to do it but w/e

#23: another example

An old trick - very cheap, super blur!

shader 0 "blur" [ @fsvs END ] [
@fsps
TEMP dtc, sample2;
MAD dtc, sample, 0.1, 0.7;
MUL dtc, fragment.texcoord[0], dtc;
FRC dtc, dtc;
MAD dtc, dtc, 64, -32; //blur offset
ADD dtc, dtc, fragment.texcoord[0];
TEX sample2, dtc, texture[0], RECT;
MOV result.color, sample2;
END
]

Damn - where's the edit post button?
Lets make that a little more efficient...

shader 0 "blur" [ @fsvs END ] [
@fsps
TEMP dtc;
MAD dtc, sample, 0.1, 0.7;
MUL dtc, fragment.texcoord[0], dtc;
FRC dtc, dtc;
MAD dtc, dtc, 64, -32; //blur offset
ADD dtc, dtc, fragment.texcoord[0];
TEX result.color, dtc, texture[0], RECT;
END
]
