VDBs

[jasonwebb]

A coding technique (data structure) used for volumetric modelling and simulation, standard in VFX software like Houdini. Stands for "Volumetric, Dynamic grid that shares several characteristics with B+ trees.". Kind of like an octree, but has the advantage of not wasting any storage space or computing power on empty voxels.
