G'day!
Well it's my first showcase of a project since my transition from A5 Standard to A6 Extra
This is my entry into the Shader Contest.
In the demo you can see soft particles (actually sprites, because we can't apply shaders to particles yet) and God-rays from unlimited sources (local or global), as well as a hair-shader (not as in "fuzzy" hair, as in Anisotropic lighting based on the direction of hair-flow). Now, I know there are hair-shaders around, but I've never seen one, so this is what I came up with and I think it looks pretty good
There's also basic normal-mapping (I have always had trouble with normal maps form blender; LC and I solved one part of it earlier, but somehow I never realised that the red-channel was the wrong way around as well!).
If you have MRT support (the demo will figure that out for you and let you know if you don't, but according to a recent poll which surprisingly few people voted in "everyone" should support it
), you also have
unlimited dynamic lights, soft lights, and "darks" -- occluders that are basically lights that take away light.
These occluders are very useful for soft drop-shadows -- I know it's fairly easy to have a sprite sit underneath you that looks like a drop-shadow, but these will occlude light from nearby objects and behave much more realistically than a moving sprite. Also, since each light/dark is actually a sprite, drop shadows can be very small, thus taking up very little screen-space, and run
very fast (in my demo I could have well ever 100 before going below 60 fps). Attach them to your character's feet for good-looking soft light occlusion.
You can download it
here, or from the Acknex resources page when George puts up the contest entries.
There's no gameplay, but if you want to see how many lights you can fit on-screen before you go below 60fps, or just want to see some of the effects then go for it.
Controls:
Standard default functions (F5 change res, F6 take screenshot, alt+enter fullscreen),
WASD move camera
QE move camera in and out
Cursor keys rotate model
1,2 -+ light
3,4 -+ ball
5 hide head
6,7 -+ sunlight
8,9 -+ tonemapping
0 enable/disable God-rays
- temporary smoke emitter
= enable/disable soft particles
The hair shader can be seen on the balls, on some plants in the background, and the old man's hair and eyebrows, although because his hair doesn't go very high you can't see the hi-lights unless you roll him over (up-down cursor-keys).
Okay, there you go. I hope you check out all the contest entries and see what some of the users here can do with shaders

PS: I forgot to include in that .zip file the Lite-C sourcecode to make it all work. There's not much, but you won't get far using the shaders yourself without it. I'll upload it soon.
PPS: I'm looking for work
Shaders, art, models, programming, whatever
I'll post up a Job-seeking thread later.
EDIT: Lite-C source included as well now. Same link.
