CGAL 5.1.4 - 3D Triangulation Data Structure
|
Various algorithms using a triangulation data structure, such as Delaunay triangulations or Alpha Shapes, must be able to associate a state to a cell elemental. For efficiency, this information must be stored directly within the cell.
This class is only meant to store a state (Boolean). Consequently, the state must be the default value (i.e. false
) unless a setting function (mark_in_conflict()
, etc.) has been called.
The three states are "in conflict", "on boundary", and "processed". By default, a cell is not in conflict, not on boundary, and not processed.
Setting | |
void | clear () |
Clears all flags: the cell is neither in conflict, nor on the boundary, nor processed. | |
void | mark_in_conflict () |
Sets the "in conflict" state to true . More... | |
void | mark_on_boundary () |
Sets the "on boundary" state to true . More... | |
void | mark_processed () |
Sets the "processed" state to true . More... | |
Access Functions | |
bool | is_clear () |
Checks whether the cell has default state (not in conflict, not on boundary, not processed). | |
bool | is_in_conflict () |
Returns whether the cell has been marked as "in conflict". | |
bool | is_on_boundary () |
Returns whether the cell has been marked as "on boundary". | |
bool | processed () |
Returns whether the cell has been marked as "processed". | |
