Simulating Dust Trail with Helicopter Landing VFX | Blender & Houdini FX Tutorial
Experimenting with VDBs in HoudiniFX..
VDB stands for Volumetric Data Block Or Voxel Data Base.......It is a library of voxels with their unique properties..which was first developed by Dreamworks Animation
Imagine a picture which consists of individual pixels....Pixels are two dimensional with only x and y axis
Similarly to form volume in 3 Dimensional space you need voxels which are 3D unit cubes...
These voxels have some certain attributes ..like velocity... temperature and density...and which direction to go in the next frame
Volumes find application in simulating phenomena like smoke, dust, fire, and water, where traditional mesh data is insufficient to capture their dynamic behavior..
