Hi!

It would be great to have Ambient Occlusion Shadow.

Ambient occlusion on wikipedia

But thanks for reminding the devs while they’re working on a release ;O)

now gold var have released; why i’m not finding Ambient Occlusion function or class

@wenzi: it is not yet implemented

This blog post http://blog.bwhiting.co.uk/?p=383 can be a starting point of implementation.

Bump!

I hope this is on the list for 4.1, otherwise I’d like to vote for it again.

The competition are offering this now.

This one blew me away,
http://codeflow.org/webgl/deferred-irradiance-volumes/www/
Tons of stuff going on there.

We have similar work being dev for a while. Problem is that it’s very demanding, especially on mac side. The beautifull alternativa demo for instance, cooks my 3 yo MBP and runs mostly 8 fps with irregular jumps to 40.

The other link shows a loading bar stuck at 50%

The alternativa demo is calculating every frame. Normally one cycle would be enough for static objects, so a lot less demanding.

I hope you get to see the WebGL demo. Try another browser maybe?
While I don’t see WebGL as any real alternative at the moment, this particular demo goes out of it’s way to show the inner workings of some pretty special lighting effects.

edit: Oh, I didn’t see it’s been posted already. Sorry.
WebGL demo is amazing.

Here is some info on global illumination and multiple lighting methods with code in C#. Perhaps someone will find it helpful.

In computer graphics, ambient occlusion attempts to approximate the way light radiates in real life, especially off what are normally considered non-reflective surfaces.
Unlike local methods like Phong shading, ambient occlusion is a global method, meaning the illumination at each point is a function of other geometry in the scene. However, it is a very crude approximation to full global illumination. The soft appearance achieved by ambient occlusion alone is similar to the way an object appears on an overcast day.
