◆ createNewSubMeshFromSelection()

ccSubMesh * ccSubMesh::createNewSubMeshFromSelection ( bool  removeSelectedFaces,

Parameters
removeSelectedFacesspecifies if the faces composed only of 'selected' vertices should be removed or not
indexMapif an index map is provided, it will be used to 'translate' global indexes
