Things to do on a mesh

Properties

• face_prop[_mut]
• vertex_prop[_mut]
• edge_prop[_mut]

Iteration

• edges[_mut]
• faces[_mut]
• vertices[_mut]

Neighborhood search

• Of Vertex:
  • edges_around_vertex V→E
  • faces_around_vertex V→F
  • neighbors_of_vertex V→V
• Of Edge:
  • vertices_of_edge E→V
  • faces_of_edge E→F
  • (neighbors_of_edge)? E→E
• Of Face:
  • vertices_of_face F→V
  • edge_of_face F→E
  • neighbors_of_face F→F
• For all functions that don't return a fixed number of elements, we probably want a number of different kinds:
  • Returning a Vec
  • Taking a &mut Vec
  • Returning an iterator
  • Taking a closure and function as a visitor

Neighborhood query?

• V:V
• V:E
• V:F
• (E:E)?
• E:F
• F:F

Modify

Delete

• remove_vertex
• remove_edge
• remove_face

Add

• add_edge
• add_face
• add_vertex

Implications

V→V => V:V 
V→F => flook, V:F, V:V (bei tri-meshes, sonst kompliziert)
F→V => V:F, F:F
F→F => F:F

V:V => -  
V:F => -  
F:F => - 

flook => -

------------------------

V→V & V→F => -
V→V & F→V => -
V→V & F→F => -

V→F & F→V => V:V, V→V, F→F
V→F & F→F => -

F→V & F→F => -
