I see no way for any collision. > Can I force a TPad, once a 3d > geometry is made, to use a TJView as opposed to a TView? Have a look tutorials/basic3d.C and TView::TView(Int_t system) ctor. That macro creates its own view. That you may replace with your own one, namely instead of // creating a view view = new TView(1); view->SetRange(5,5,5,25,25,25); do // creating a view view = new TJView(1); view->SetRange(5,5,5,25,25,25); Pay your attention on the statements from TView::TView(Int_t system) It "says: gPad->SetView(this); You should provide something like this either "inside" of your TJView ctor or "outdoor", some where in your macro/code. For example for "basic3d.C" // create a pad p1 = new TPad("p1","p1",0.05,0.02,0.95,0.82,46,3,1); p1->Draw(); p1->cd(); // creating a view view = new TJView(1); view->SetRange(5,5,5,25,25,25); p1->SetView(view); // this is "outdoor" version Hope this helps, Valery Hope this helps,
