Feature Topology Levels
Level 0 (2D or 3D coordinates)
- One or more pairs of Feature Nodes are collocated
Level 1 (2D or 3D coordinates)
- No Feature Nodes are collocated
- One or more pairs of Feature Edges have intersecting interiors
Level 2 (2D or 3D coordinates)
- No Feature Edges have intersecting interiors
Level 3 (2D or 3D coordinates)
- 2D topological surface completely partitioned into non-overlapping faces
Level 4 (3D coordinates)
- Edges and perhaps faces “sticking out” of 2D topological surface
Level 5 (3D coordinates)
- 3D topological space completely partitioned into non-overlapping volumes
