4 Q3Mesh_GetEdgeComponent

You can use the Q3Mesh_GetEdgeComponent function to get the component of a mesh to which an edge belongs.

TQ3Status Q3Mesh_GetEdgeComponent (
TQ3GeometryObject mesh, 
TQ3MeshEdge edge, 
TQ3MeshComponent *component);
mesh A mesh.
edge A mesh edge.
component On exit, the mesh component that contains the specified mesh edge.

DESCRIPTION


The Q3Mesh_GetEdgeComponent function returns, in the component parameter, the mesh component that contains the mesh edge specified by the mesh and edge parameters.

SPECIAL CONSIDERATIONS


The Q3Mesh_GetEdgeComponent function might not accurately report the mesh component that contains a mesh edge if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
