Details for implementation see in this video:

Here is a more general video but its 1 year old.

Why is OpenCL so important for the future of Raytracing?

Some years ago we had two versions of POV-Ray, one version with SSE, and one
"Normal version". How much faster was this SSE-Version really?
1,2,6 times faster?

Thats nothing compared to what you can reach using OpenCL and a actual GPU.
We are starting with 10x and going up to 30x faster.

Here is another example realtime Particel-Physics for streamlining objects:

See the future ...

The source to POV is freely available. Please, do like the makers of 
isoPOV or MegaPOV have done, and release a custom version showing us 
what you can do!
