From the developer that spearheaded Blender's volumetrics (among other new features) comes the great hope of Sculpting Dynamic Subdivision.

The first time I saw voxel sculpting in 3D Coat I said to myself: I hope one day we have in Blender Voxel Sculpting! But at that time I hadn´t the necessary skills to start the project, so I pushed it to my todo list. What captivates me more about Voxel sculpting, is the “Unlimited Clay” freedom, you don´t have to worry anymore for polygon stretching and instead you can focus on the art itself.
Then , suddenly, Sculptris came to the scene, a very small and well designed application with an incredible feature: Sculpting tessellation or subdivision on the fly! it was not voxel based at all
but provides similar freedom: unlimited clay to sculpt!
...the algorithm proves to be not difficult at all. ...a Blenderartist thread wake up my sleeped interest in Sculpting Dynamic Subdivision: and after two sleepless nights I have a working prototype!!!!!
The video will show you the true power of it, is very difficult from some stills to get the idea.
