What you can do with your VDB file
See the volume in 3D
Turn and zoom the 3D view of the volume. Volume Rendering shows the whole volume at once.
Browse the slices
Voxels Slice shows the volume slice by slice as an image (with Volume Rendering off).
Set the iso level
Change ISO sets which value the 3D surface of the volume shows.
Check the dimensions
The Information panel shows the voxel grid, the voxel size and the size of the volume.
How to open a VDB file in 3 steps
Open your VDB file
Click Open Files in the viewer above, then Browse… and pick your .vdb file. It opens as a voxel volume in your browser, with no account and no install.
Look at the volume in 3D
Drag to turn the volume and scroll to zoom. Volume Rendering shows the whole volume; turn it off again to see it slice by slice with Voxels Slice.
Set the iso level
Change ISO sets which value the 3D surface shows. Building a mesh from the volume is in the desktop app (paid plan).
