|

|
|
|

|
|
List of mesh edges connected to vertex. For this routine to work
|
|||
|
|
|
|||
|
|
properly, one must call MESH\_BldAdj first. If not the routine will
|

|
|
|

|
|
just return 0.
|

|
|
|

|
|
If the vertex is a parent vertex, then the operator will return all
|
|||
|
|
|
|||
|
|
the edges connected to all the child vertices of the vertex. The edge
|
|||
|
|
|
|||
|
|
returned will be of type PARENT. Each of these edges will be made up
|
|||
|
|
|
|||
|
|
of 'v' and any other parent vertex it is connected to. If it is a
|
|||
|
|
|
|||
|
|
child vertex, then it will return edges connected only to itself. In
|
|||
|
|
|
|||
|
|
this case all the edges will be of type CHILD. Each edge will be made
|
|||
|
|
|
|||
|
|
up of the child vertex 'v' and any other child vertex it is connected
|
|||
|
|
|
|||
|
|
to. Note that vertices on 2-manifold (single material) boundaries and
|
|||
|
|
|
|||
|
|
in the interior can be considered a parent or a child as required.

When finished with the list of edges, call ME\_Delete on each of the

The behavior of the operator for parent and child vertices is the same

as it is for MV\_Edges.

List of mesh regions connected to mesh vertex. For this routine to

|

|

work properly, one must call MESH\_BldUpAdj first. If not the routine
|

will just return 0 for the number of regions and a NULL pointer for

the region list.

For a parent vertex, mesh regions in all the material regions
|

connected to all its children are returned. For a child vertex, only

mesh regions in the particular material region pointed to by the child
|

|
|

Depending on the type of the attribute, the appropriate field will be

filled on succesful completion. Arrays are returned in pval, integer in

rank, one sends in a value with the right variable
