Function Documentation

MMGS_assignEdge()

int MMGS_assignEdge

(

MMG5_pMesh

mesh

)

Parameters

mesh	pointer toward the mesh structure.

Returns

1 if success, 0.

Copy the properties (ref and tag) of the declared edges to the triangles, where they are assigned to the individual corners of the triangle. First a hash is created for rapid lookup of the edges. Then in a loop over all edges of all triangles, the hash is probed for each edge, and if it exists its properties are copied. Thus, declared edges that do not occur in any triangle will be silently ignored.

Remarks

this function handle all the provided edges.
