Creates a new sub mesh with the selected vertices only.

This method is called after a graphical segmentation or by ccMesh::createNewMeshFromSelection. It creates a new sub-mesh structure with the vertices that are tagged as "visible" (see ccGenericPointCloud::visibilityArray). This method will also update this sub-mesh if removeSelectedFaces is true. In this case, all "selected" triangles will be removed from this sub-mesh's instance.

    \param removeSelectedFaces specifies if the faces composed only of

'selected' vertices should be removed or not

Parameters

indexMap if an index map is provided, it will be used to 'translate' global indexes

◆ createNewSubMeshFromSelection() [2/2]

		const std::vector< int > &	selectedTriangleIndexes,
		IndexMap *	newRemainingTriangleIndexes = `nullptr`
	)

Creates a new sub mesh with the visible vertices only.

Parameters

removeSelectedTriangles	specifies if the faces composed only of 'selected' vertices should be removed or not
selectedTriangleIndexes	a map of the triangles indexes that will be used in the new sub msh (or -1 if they are discarded)
newRemainingTriangleIndexes	if an index map is provided, it will be used to 'translate' global indexes of triangles remaining in the source sub-mesh

Returns: the new sub-mesh if successful
