VDB commonly refers to Volumetric Database files, a format for storing sparse volumetric data such as smoke, clouds, and fire.
VDB files store volume data efficiently, making them useful for effects like smoke, fog, clouds, explosions, and other volumetric elements. In Blender, VDB assets can be imported and rendered as volume objects, often in path-traced scenes.
The points that define the corners and structure of mesh geometry.
Vertices are the individual points in a mesh. Edges connect vertices, edge loops flow through them, and faces are built from them. Most mesh modeling operations, including Extrude, loop cuts, and subdivision, ultimately change how vertices are arranged.
Rendering or simulating material that fills space, such as fog, smoke, clouds, fire, or mist.
Volumetrics describe effects that exist through a volume instead of only on a surface. They can scatter and absorb light bounces, which makes them important for atmosphere, smoke, clouds, and cinematic lighting. Volumetrics are commonly rendered with Path Tracing and can be stored in VDB files.
