Q3Mesh_GetNumComponents
You can use the Q3Mesh_GetNumComponents function to determine the number of connected components of a mesh.
TQ3Status Q3Mesh_GetNumComponents (
TQ3GeometryObject mesh,
unsigned long *numComponents);
mesh
- A mesh.
numComponents
- On exit, the number of connected components in the specified mesh.
DESCRIPTION
The Q3Mesh_GetNumComponents function returns, in the numComponents parameter, the number of connected components in the mesh specified by the mesh parameter. A connected component is a list of vertices, each of which is connected to all the others by some sequence of mesh edges. For example, a mesh that contains two cubes has two components.
SPECIAL CONSIDERATIONS
The Q3Mesh_GetNumComponents function might not accurately report the number of connected components in a mesh if called while mesh updating is delayed (that is, after a call to Q3Mesh_DelayUpdates but before the matching call to Q3Mesh_ResumeUpdates).
