What about Approximated Indirect Lighting?

Do yuou remember the BigBuckBunny blog’ post where AAO was discussed? (http://www.bigbuckbunny.org/index.php/approximate-ambient-occlusion/)
Well, among the Blender official docs i found this page (http://www.blender.org/development/release-logs/blender-246/approximate-ambient-occlusion/) where the same thing is explained and a few links are given. Now, take look at the PDF. (EDIT: or just look at its content at this page: http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter14.html) It also explain how to achieve approximated GI using tweaked AAO techniques (as far as i understand). The feature is described in a few lines, so it seems to me (totally ignorant) almost trivial to implement.
Am I right?? And just in case… is there any talented dev who didn’t notice this possibility to have cheap&fast GI in the internal? (and wants to try…)

if you’d propperly read the BBB blog post you’d noticed that brecht got a one bounce ‘prototype set up’ to work,
but didn’t consider it fast enough for peach at the time, so left it un-finished:

Further work could also make this method usable for a single bounce of indirect lighting, though I don’t think we will be able to use that for Peach. A quick prototype implementation showed that this method could indeed support it fairly well, but performance it is likely not fast enough for Peach.

Yep, I knew he considered that.
What I meant is: “not fast enough for Peach” but maybe fast enough for other users?
The Nvidia tests with that “sort of” cornellbox look quite good…

Lighting with GI i don’t expect fastness anyway (despite the cheap&fast slogan I used earlier). This implementation could be slow for animation shorts, but acceptabe for other usage. And at least could be some kind of GI :yes:

No, no, you misunderstood the point of my post,
that he didn’t consider it a viable feature at the time for BBB specifically,
had plenty of other things to work with, but it’s definitely a feasible feature,
and if he gets time and has the interest he might just come back to this. :slight_smile:

yeah, something like that would be nice. good that you brought it up again. probably the developers totally forgot about it. :stuck_out_tongue:

and it would be cool if this could be baked. i am not sure if every new render feature automatically is bakeable or if baking has to be worked on separately?

yesyesyes… forgetful devs… :stuck_out_tongue:
