Might this be useful for the Diaspora guys?

[pecenipicek]

Down here is the code for the post-f.sdr
I took it from here and modified it a bit to work with the stuff that Hery put in. Also, note that it will be applied in every mission regardless of settings, if you dont use hery's mission. If you do use it, the effect dissappears when the other shaders kick in.

I know i'm a hack, however, i'm not pretending to know how to code, so i do the best i can and the best i know (in this case not much)...

Unfortunately, without a nice bright background, you're not gonna get it all that bright. it basically darkens the dark areas and brightens the bright ones.

Well last time I remember looking at "bloomed" screenshots everything including the HUD was effected, this looks pretty good.

Why pick on us? As far as I can see this would be useful for everyone.

[Zacam]

Could you imagine what, oh, Ransom could do with scripting or sexp triggering different shaders?

Hot damn.

[pecenipicek]

Could you imagine what, oh, Ransom could do with scripting or sexp triggering different shaders?

Hot damn.

Hery did use events for his transitions. Its refreshing to see a new member appear with such shinies xD

[edit] modified my post before with the shader just for bloom.

Well last time I remember looking at "bloomed" screenshots everything including the HUD was effected, this looks pretty good.

if i remember correctly, that was an ati driver-based shader called HDR-ish, not comparable to this, since this is rendered directly in-engine.

Give me slight desaturation, a bit of grain and just a touch of bloom and I'll be a happy dev.

[pecenipicek]

by using the shader i have up there you could get just that. tweak the options a bit and you're set.

[General Battuta]

Whoa. Could the masses get some screenshots of this?

[pecenipicek]

as soon as i fix a showstopper bug... if there are enough bright things on screen, it simply blacks out. i'd wager that a buffer somewhere at a point decides to scream and says **** you.

also, disabling the hud while using the bloomy shader, results in the same effect. (this applies to all three postprocessing codes, Hery's, the mix of hery's and the bloomer, and the bloomer only)



also, hery's code seems ok, so its probably the additional framebuffer that kills the hud disableage. not 100% sure on this one, someone more experienced with OGL might want to check.

[Tolwyn]

For projects like SoL and Diaspora, a new rendering engine will probably be ready too late to be used in the release.

Probably? 

[pecenipicek]

after extensive tracking and such, the bug is related to the additions enabling the post-processing switch and probably the extra code pertaining to the switch. i am currently looking for a way to implement the bloom into Hery's main shader "repack"

@pecenipicek: I modified your code, so now it works even when "my" effects are on. Unfortunately, current shaders system is not prepared to configure post-processing shaders using GLSL preprocessor.

I've also noticed that when for some reasons (file not found, compilation error) shaders are not enabled, post-processing uses fixed-pipeline and some problems appears (and in that case rendering to texture is pointless since there is no way to apply any effects to it). Despite the fact that behaviour is quite obvious, I forgot about it. Updated patch will be available soon

Update:
Problems when hud is disabled: solved. Keeping post processing enabled when impossible to use shaders: solved.

This looks excellent! great work!
cant wait to link it with capships explosions and the white "flash", turning up the contrast as well as the bloom effect for a few seconds
is there a way to implement this only when looking at something?

[Colonol Dekker]

I'll test it on my notebook tomorrow. It has a slightly less powerful gfx chip (GF 9600M GT).

I think that should be around the lower mainstream class of gfx cards today. So pretty much the minimum for FS2 to run on decent quality settings.

I'm running on 2 8 series cards. Don't price me out of the upgrades yet. . .

[chief1983]

Has everyone doing any development related to this played HL2:  Lost Coast with the commentary on?  If not, do it MEOW.

[Hery]

Problem with cutscenes: solved.

@Nighteyes: since saturation, contrast and distort noise are enabled by sexps, and bloom will be enabled by sexps, I don't think there will be any problem to do that

[pecenipicek]

ah, yes, hery, in your shaders, it'd be better to use mix() instead of lerp() since lerp is a CG command, not GLSL... same goes for fmod.


also, nice work

[Hery]

I started programming in GLSL a few days ago and Cg/HLSL habits still remain

Contrast increase, not bloom, seems to be used more in the show. Anyway bloom is overused.
