This is pretty impressive to be realtime and in your browser using WebGL.

Add TheaRender to that list, it was the first renderer to support those poolcaustics.

As I understood it, RC used a fake approach for the caustics (

Am also eagerly waiting for this

Haha, no, I'm pretty sure there were many render engines that did "pool caustics" before Thea. Mental ray, v-ray, renderman, pov-ray, etc. etc...
Thea and RC use similar techniques to achieve those caustics.

it would be no problem for me if maxwell would do it the same way...

Thanks for clarifying, Bubbaloo.
Cant agree on this, numerobis, I need the real deal. Working with RealFlow meshes all the time, I cannot apply these fake techniques..

I know that Thea was not the first in the universe to have this, don't be silly Bubba. In the mix of so called 'unbiased' engines it was amongst the first to introduce this feature.
Most likely it's cheating like the rest but it can still get the job done.
