Irradiance map for animation

[vlado]

Following the discussion in this topic
http://www.chaosgroup.com/forum/phpB...ic.php?t=17670
most of the voters wished for a method of producing flicker-less GI animations... so here are some of the first results in this direction:

The method used expands on the already existing time interpolation for the irradiance map that is currently used for motion blur. This was simply extended to do the time interpolation over the samples of several irradiance maps for adjacent frames. This helps to greatly reduce the flickering in the resulting animation.

All animations are directly from the render, there is no additional compositing involved (e.g. separation into moving/static objects).

Impressive...

Is there a build coming soon ???



Any infos about render's speed ???

For the sponza scene towards the end of the animation, the irradiance maps were calculated at about 1 m 40s to about 2 m per frame, while the final frames rendered at about 1 m 10 s per frame. This was on a machine with 2 dual-core processors (4 cores total).

Animations looks nice, especially the Ape one, where the ape is all smooth and soft-looking, and the detail in the greebled wall is steady and sharp.
Lovely lovely!

looks great - it'd be great to see all the settings you used for this also - i.e. AA settings, noise thrresholds etc.

Looks really promising - great stuff.

Well, we've been wanting this for a looong time, just never thought it would be possible. Great news, when can we expect to have this feature?

Impressive, but what about showing original sequence files (several uncompressed frames from animation) to look thoroughly

You can find some uncompressed frames here:

Note that I am not saying that this produces absolutely no flickers; only that it reduces flickering a lot
