Fake AO Test in Blender Game Engine

A test of an idea I had, to fake simple point-based ambient occlusion in the Blender Game Engine, by parenting a negative lamp to an occluding object. The technique I created here is simple, but could be extended to things like moving characters. Just parent a negative lamp to the foot bone of a walking character, and the ground will be correctly occluded when the foot touches ground.

yeah i had this idea too, but when i test in bge, the negative light returns positive. when i simple test on the scene is black, when i press p it's white. why?

[eedobaba7726]

yes, this happens in 2.49, I should have mentioned. As you can see, I'm using 2.5, where that bug has been fixed.

Pretty awesome idea, it looks great. My only worry would be performance when theres several of these in a scene, probubly wouldn't be worth doing until lights are optimized further.

[eedobaba7726]

That ocurred to me, and I think performance with this method could be improved by just changing the interpolation of the light to something simpler to compute than a bezier curve, like a linear falloff.

What are you doing to get it to show the occlusion in real time? I can only see it in the game engine.

Sounds interesting, perhaps you could let me know more about it? Or maybe make some tutorial? Cheers! :-)
