Screenshot of the Month May 2011 [Winner Announced!]

What you can see:
Deferred rendering
Normal mapping
Antialiasing
Bloom(it's very subtle, I like it that way)
Oh, and to do the lighting calculations instead of quadratic or linear attenuation, I use logarithmic attenuation. It's something I came up with while sitting in school

Height2Normal v. 2.1 - convert height maps to normal maps
Step back! I have a void pointer, and I'm not afraid to use it!

Talking about lighting calculations, when looking over shaders found in examples and tutorials online I see a lot of people doing their lighting in gamma-space instead of linear space, which actually gives a skewed result (since you're working with a curve)ent1ty wrote:iOh, and to do the lighting calculations instead of quadratic or linear attenuation, I use logarithmic attenuation.

eg. Say you would multiply your scene output by (0.5, 0.5, 0.5, 1.0) (RGBA), in linear space this would result in your final output color actually being half as bright as the color before doing the calculation, while you wouldn't even get close to this in gamma space
I made the switch from gamma space to linear space in my lighting calculations a while back, and it takes a while to get used to, but it feels more natural to do calculations this way
And about your screenshot:
Looks nice, although I think only normal mapping is not enough for those walls, would be better with some parallax mapping
Everything else looks great though
Yes, I am working on parallax mapping right now.
About your gamma space - I don't quite understand. Could you make it clearer(or post some link)?

I don't know possibly...
But, I changed it anyway. Thanks
Someone college walked by and talked about weeks instead and since I was already late for the competition and in a hurry that went wrong
