Domains
Domains refer to what type of geometry element the attribute corresponds to. The domain determines how attribute values are interpolated to other domains. Interpolation is simply averaging values in most cases (ie. the values for each component in a vector3 are added and divided by 3) but in the case of Booleans there are special rules (see below).
| Domain | Description |
|---|---|
| Point | Single locations in space with a position:
|
| Edge | Edges of meshes. |
| Face | Faces of meshes. |
| Face Corner | Corners of faces of meshes. Example: UV map attribute. |
| Spline | Group of connected curve control points. |
