I'm using CGAL edge collapsing to remove edges on mesh and it's working successfully .
But I want to run the edge collapsing process within selected surface on mesh viewer .
I preview the Geomview (.off ) using the following code:
QWidget* centralWidget = new QWidget(viewer); centralWidget->setSizePolicy(QSizePolicy::Maximum,QSizePolicy::Maximum); setCentralWidget( new CGAL::SimpleLCCViewerQt<LCC, CGAL::DefaultColorFunctorLCC>(&qWin , lcc, "Basic LCC Viewer", false, fcolor ) ); show();
So, How Can I select specific surface region on mesh viewer and apply the edge collapsing on the selected surface only ?
I appreciate any help .
