What are you working on?

[Spike]

personally I'd use a 3d texture for a lookup (should be possible to get a single channel one, hopefully it won't loose too much precision). you then need to convert it back, of course. a 1d texture. using a 2d screen texture.
I think that's all the dimensions covered, lets just hope noone wants to use a cubemap.

3d textures to tint stuff in a post processing shader are a moderately common technique. you can apply the same colour transforms to both a screenshot and a 2d version of the 3d texture, and those same colour transforms can then be applied to the live output. approximately, anyway. depends on the resolution of the 3d texture. anyway, its a fun technique that might be useful on a per-map basis.

For now I made this thing like this, in default.glsl in the USEPOSTPROCESSING part:

Code: Select all

dp_FragColor.r = int(dp_FragColor.r * UserVec1.x) * (1 / UserVec1.x);
dp_FragColor.g = int(dp_FragColor.g * UserVec1.x) * (1 / UserVec1.x);
dp_FragColor.b = int(dp_FragColor.b * UserVec1.x) * (1 / UserVec1.x);


May need to boost r_hdr_scenebrightness in some dark game levels when using low posterize levels. Also when using level 1, it may be a good idea to set gl_polyblend to 0, otherwise screenflashes/underwater are black. Or use a level above 1, but below 2. It would still appear with 8 colors.

Maybe that palette lookup is still a bit over my head. But I'm happy I got this Posterize effect working...

very dramatic effect, jim. I like it A LOT

[ceriux]

Made some user adjustable Posterize effect with a Post Processing filter... Maybe I continue it further and try to make another that use the game palette, if that's possible?

dude that looks awesome!

Might look cool in conjunction with black sobel outlines (or rather, creases?) to retain visibility of forms in the underexposed areas.

You should get some dither in there as well

If I could just get it work. I was able to get the palette to be used, but then the framerate was 5 seconds per frame. I'm probably doing it some way wrong. 16 color palette worked sort of ok, but turning on rt lights had a drop in fps. Apparently a for loop to find the colors from an array is not a good idea...

Over at func for the last month there has been a map jam event running and the final map pack is complete with 12 authors creating new maps. The map jam was based on the theme of the awesome map Honey and as you can see from the screenshot lots of people created different styles.

Is it possible that this could be added to the inside3d site front page news?

Working on a silly little level for OpenKatana's Capture the Flag gamemode.

Heh, looks like a place where lots of people have minus score Could have wider areas to move around.

Trying out some more post processing. I was able to get a 16 color palette to work a little faster when I didn't get the colors from some array. It's playable in some settings, but drop from 260fps to 160fps seems a bit too much. The earlier posterize effect only dropped to 250fps. Rt lights drop it down to 90fps, and 75fps together with the 16 color effect. These when staring into a wall at 1920x1080 res. Looking at some 10 models/more level, drops the fps 60% from the wall staring.

OK, I'll bite: what is it ?

Very very cool.Love the face, love the snake. But hot smoking chicks don't have sick abs.
