brightness is additive, contrast is multiplicative, gamma is exponential.

the code you (baker) linked is contrast, not brightness as you claim, nor gamma as the code appears to claim. these things all have quite specific definitions. :s

both contrast and brightness can easily be rendered using the appropriate combiners stuff (potentially requiring multiple passes). actual gamma requires glsl or hardware gamma ramps.

all this stuff will have the effect of slowing down the game.
its worth spending the time to add support for fragment shaders, if only to also fix the uglyness of water and skies... 

I'm monkeying with this from QC :D 

what's the fullscreen gamma bug you get?

When game runs in fullscreen, after a few seconds, or intermittantly, game goes quite dark. Longstanding and confusing thing.
Since it is seen to our SDL2 build too, maybe it is connected to our launcher ?

I think if i install libSDL.so and Quakespasm like on an ordinary Unix , there is no bug. 

Yeah sure except note the following ...

the code you (baker) linked is contrast, not brightness as you claim

The standard Quake brightness cvar is called "gamma" -- I wasn't about to change a cvar name everyone has used for 15 years ;)

And the function was named SCR_Brightness by MH so I kept the name, besides the slider bar is called "brightness."

Gamma bug.

Is a major reason why I ditched hardware gamma in Mark V. It stupidly affects Windows and OS X.

I wrote tons of code trying to catch the system event that mucks up the brightness in Windows after switching between fullscreen and windowed mode. There isn't one.

The rpath thing is fixed in a later build+package, and there should be no crashes. Here:

Not sure about the gamaa issue, though. 

Something that's always bothered me: hide the crosshair while centerprint text is on screen. Otherwise it just looks awful with the big + jammed in the middle of a word.

I've tried doing this in qc with stuffcmd, and it works okay, except there's no way to remember what the user's original crosshair preference was if the map loads or the player f9's while text is on screen. I default to just assuming everyone wants it on, but I know someone's going to come out of the woodwork and complain if I do that.

It's a tiny bit of polish that should just always happen, and the proper place for it is at the engine level. 

Don't draw crosshair if centerprint code.

Spike pointed out some mods actually strategically display console text as a status indicator.

Like Quoth's flashlight indicator bar (example map = Ruined Nation) 

Add CSQC support to Quakespasm.

This is built against and packaged with today's SDL-1.2:

And here is a test build of hexen2 along with it:

Sounds reasonable to move centerprints up 4 lines if crosshair ?? 

You probably want to head down in case the text is long... 

Guys, please, could you add the FSAA (Antialiasing) option to the OS X version ?

and also the command-Tab feature (as in Quake3) to switch app, without having to quit Quakespasm. 

Hmmm - some messages shown with SCR_DrawNotifyString are just too big to mess with positionally. But simple cases such as E1 entryway (SCR_DrawCenterString) have been moved up one line for the crosshair

@Barnak Where is the relevant command-Tab code ? Maybe i'll go look for it.

OS X FSAA has been talked about somewhere else. Maybe SDL2 with OS X makes a simple implementation possible. 

Mark V has anti-aliasing (cvar = vid_multisample, set to 2, 4 or 8) --- if you are staring at edges you can tell the difference. But who is doing that during regular game play?

I'm not arguing for or against such a feature, just saying I haven't seen anyone even comment on the availability of the feature and I forgot it myself. 

Since quake doesn't use much resources, I play it in the native resolution of my monitor, and aliasing is not such a big problem. I'm sure it looks better with, but aliasing in quake hasn't really bothered me since winquake at 320x200. 

Anyone know how to make the engine look like this? shown here 

 

 

I had it figured out. 

There are a lot of commands useful for testing maps that you can bind to a key in your autoexec.cfg file.

Examples:

bind "m" "r_lightmap"
bind "f" "r_fullbright"
bind "g" "notarget"
bind "c" "noclip"

When you don't add a value, then it will toggle. Hit the key once and it turns it on, hit it again and it's off. Quick and easy. 

some of those you need to add the word "toggle" in there (the ones that are cvars and not commands) 

I thought that was correct because copied those right out of my autoexec file. I just now thought to check and for some reason I also had the correct commands in my config.cfg, which is why it was working.

bind "m" "toggle r_lightmap"
bind "f" "toggle r_fullbright"

Not sure why I had them mixed up like that, probably from experimenting when I was first trying to get it to work.
