is SDF and VDB are same...? if not what is the difference between them?

Recommended Posts

Basically VDB is a container, SDF is a certain type of information (distance to surface, with negative numbers for being "behind" the surface).

SDF can be hold inside a VDB, but also inside a "classical" Volume.

So, no it's not the same.

 

The Link from Milad Savar is a good starting point.
