class
openalea.cellcomplex.gmap.gmap_tp.GMap[source]¶ -
-
adjacent_cells(dart, degree)[source]¶ Return all the elements of degree degree that are adjacent to the element dart with respect to the alpha relation of degree degree. (Typically all points sharing an edge with a point) For this iterate over all the dart of the orbit of (dart, degree). For each dart d of this orbit, get its neighbor n (alpha degree) and remove its orbit (n, degree) from the set of darts to consider. See function incident_cells for inspiration.
-
cell_center(dart, degree)[source]¶ Generic function to compute the center of any elements of any degree
-
elements(degree)[source]¶ Return one dart per element of degree. For this, consider all darts as initial set S. Take the first dart d, remove from the set all darts of the orbit starting from d and corresponding to element of degree degree. Take then next element from set S and do the same until S is empty. Return all darts d that where use
-
get_embedding_dart(dart, degree, propertydict)[source]¶ Check if a dart of the orbit representing the element of degree degree has already been associated with a value in propertydict. If yes, return this dart, else return the dart passed as argument

-
incident_cells(dart, degree, incidentdegree)[source]¶ Return all the element of degree incidentdegree that are incident to the element dart of degree degree. (Typically all edges around a point) For this iterate over all the dart of the orbit of (dart, degree). For each dart d of this orbit, get all the darts coresponding to the orbit of the element (d, incidentdegree) and remove them from the original set. See function elements for inspiration.
