Q3Mesh_GetNumComponents
You can use theQ3Mesh_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
TheQ3Mesh_GetNumComponents
function returns, in thenumComponents
parameter, the number of connected components in the mesh specified by themesh
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
TheQ3Mesh_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 toQ3Mesh_DelayUpdates
but before the matching call toQ3Mesh_ResumeUpdates
).
