Teapot caustics animation.

[Sphere]

I just figured out how Corona can be used to render caustics with BDPT, so I animated a light rotating around a teapot primitive to see how it looks.
It turns out that it looks pretty cool, so I'm posting it here.

EDIT: Can't figure out how to get YouTube embedding to work, here's a direct link.

Looks great. If only there would be solution to kill those random fireflies without suppressing rest of the image, it'd be awesome.

those fireflies are becoming trademark. pretty nice test.

Yeah it'd be lovely to have the option of a caustics pass to use as an overlay for progressive renders, it's very difficult to add any kind of noise reduction without making the whole image muddy.

Wow nice! how long did each frame take?

Around 3 minutes each.
