Deferred rendering

Daz

Just spotted this interesting presentation from Guerilla games on the use of deferred rendering in Killzone 2 and thought I'd share. We've just got this implemented in our engine, and I'm impressed so far. There are distinct pros and cons between it and forward rendering methods, namely that alpha blending and AA are more problematic (but not remotely unsolvable) in deferred lighting, but in a scene with many dynamic lights it's way more efficient. It's being used more and more in game engines these days, so I thought this PDF was worth posting:

Cheers Daz, Rick already posted this in GD although I think it fits better in this forum

Good if someone missed it before though.

Alpha in deferred is a bit of a bitch, I have to agree, but the sheer number of lights you can handle with DR is a great boon.

The Xreal Quake3 engine mod also has it implemented (and also VSM) but currently it is a bit broken it seems:

the medical vis I do for volume rendering is also using it, but you loose a bit of diversity in actual shading methods, though most meshes in a game use same principle shader anyway.
