4 Q3Mesh_GetVertexOnBoundary

You can use the Q3Mesh_GetVertexOnBoundary function to determine whether a vertex lies on the boundary of a mesh.

TQ3Status Q3Mesh_GetVertexOnBoundary (
TQ3GeometryObject mesh, 
TQ3MeshVertex vertex, 
TQ3Boolean *onBoundary);
mesh A mesh.
vertex A mesh vertex.
onBoundary On exit, a Boolean value that indicates whether the specified mesh vertex lies on the boundary of the mesh.

DESCRIPTION


The Q3Mesh_GetVertexOnBoundary function returns, in the onBoundary parameter, the value kQ3True if the mesh vertex specified by the mesh and vertex parameters lies on the boundary of the mesh. Q3Mesh_GetVertexOnBoundary returns kQ3False otherwise.
