#41

Nah, but my strategy was simple:

Render the entire scene to a texture larger than the viewport (or rerender the entire scene to a 256^2 texture, whichever is faster, which depends on the complexity of your scene). Then render that texture to a texture 256*256 with a fragment shader, that calculates the brightness (you might want to compensate for the human eye sensitivity for R,G,B).

Then render that texture to 128^2, 64^2, 32^2, 16^2 textures, don’t go (much) further.

Now you additive-blend all those textures to a 256^2 texture, ofcourse you half the multiplication-factor with every smaller mipmap.

brightness = brightness*[depends_on_framerate] + (bloom256*0.250 + bloom128*0.125 * etc,etc)

Now simply draw that brightness texture on your scene. It gives the impression of being (slowly?) blinded by bright objects. You can fake a lot of effects by not hardcoding everything, but building feedback into it (from the tiny bloom maps, like 16^2. The brighter that tiny texture, the brighter your scene, and the less the bloom effect should be. This simulates your eyes very slowly (like >10s) adjusting to the brightness.

I added the feedbacking bloom as Riven described. Well, it’s a bit of a rough version of it (the scaling down of the bloom layers is done the simple and ugly way without shaders, so there’s still some popping).
It’s also currently a bit exaggerated, just to show it off (and reveal the shortcomings of the current implementation).

#43

very nice work.

maybe I’m missing the point of the game style but the ability to look around might be useful (at least when your stationary), if only to get a better feel of the room your in and where you need to go.

Also being able to side step might be nice too, could save some unnecessary turning :slight_smile:

oh, and the bloom is nice.

#44

Interesting. In my version the saturation reached much further. (like 100px)

Are you using a threshold, or some other way (square it) to ramp up the brightness in a non-linear way? (you should)

If you increase the weight of the tiny mipmaps and decrease the weight of the large mipmaps and increase the retain-factor (which causes the bloom to lag), then you’ll get a nicer effect :slight_smile:

#45

Diagonal movement (for both the player and the robots) would kick ass, too.
