Q3Mesh_GetEdgeOnBoundary

You can use the Q3Mesh_GetEdgeOnBoundary function to determine whether a mesh edge lies on the boundary of the mesh.

TQ3Status Q3Mesh_GetEdgeOnBoundary (
TQ3GeometryObject mesh, 
TQ3MeshEdge edge, 
TQ3Boolean *onBoundary);

mesh

A mesh.

edge

A mesh edge.

onBoundary

On exit, a Boolean value that indicates whether the specified mesh edge lies on the boundary of the mesh.

DESCRIPTION

The Q3Mesh_GetEdgeOnBoundary function returns, in the onBoundary parameter, the value kQ3True if the mesh edge specified by the mesh and edge parameters lies on the boundary of the mesh. Q3Mesh_GetEdgeOnBoundary returns kQ3False otherwise.
