What are you working on?

uhh, John, it looks very cool

realtime lava surfaces lighting

@Irritant: I love the passion you're putting on CRX engine! Can't wait to see final results!

@Barnes: it seems a cool effect but maybe a video could show all of its beauty

@hogsy: very interesting lecture. I still find, but maybe because I'm just a noob at programming, that it doesn't seem to me that second block of code (the C-one) is unmessy compared to the first one. I still think that a clean and working code can be done even in quakec. With fteqcc, infact, you have most of the worktools of C (structs, arrays) but you don't have to face some obscure (at least for me ) treats like pointers!
But anyway, thanks for that article, really appreciated!

Thanks Barnes! Parallax mapping is an awesome effect! What kind of performance drop do you have setting it on/off?
PS: I understood that lava content emits dynamic light! That's why I couldn't see any difference from the image you posted! But, what's the difference between content_lava and a wall, for example?

Ooh nice, cone stepping, the only parallax mapping I actually like visually
How long does it take to preprocess the CSM?
I rendered out some in xNormal before, regular CSM was okay (still fairly slow) but the relaxed variant took forever to render.

I spent a few hours in order to alter the height map in csm maps. As a result, the size of re-texture increased by 500 megabytes. If we compare the speed - csm is approximately two times faster than pom or relief mapping. But if you use optimized algorithms for relief and pom and then the speed is approximately equal. CSM slightly faster (5-10 fps) with optimized shader.

csm map is rgba texture -
Red: inverted heightmap
Green: sqrt (Cone_Ratio)
Blue: df/dx
Alpha: df/dy
But shader use only RG channels

fog lights (jail5 relight)

[Irritant]

Wow that is stunning!

[toneddu2000]

so beautiful!Compliments!

bsp2 (and 2bsp) map support thanks to reading quakespasm code, plus bsp transparency from Makaqu. Possibly bugs, and only one transparency pass for now.

that looks sexy.
