The 3D view class.

This package was originally written by Evgueni Tcherniaev from IHEP/Protvino.

The original Fortran implementation was adapted to HIGZ/PAW by Olivier Couet and Evgueni Tcherniaev.

This View class is a subset of the original system. It has been converted to a C++ class by Rene Brun.

TView3D creates a 3-D view in the current pad. In this 3D view Lego and Surface plots can be drawn and also 3D polyline and markers. Most of the time a TView3D is created automatically when a 3D object needs to be painted in a pad (for instance a Lego or a Surface plot).

In some case a TView3D should be explicitly. For instance to paint a 3D simple scene composed of simple objects like polylines and polymarkers. The following macro gives an example:

{
   cV3D = new TCanvas("cV3D","PolyLine3D & PolyMarker3D Window",200,10,500,500);
   // Creating a view
   TView3D *view = (TView3D*) TView::CreateView(1);
   view->SetRange(5,5,5,25,25,25);
   // Create a first PolyLine3D
   TPolyLine3D *pl3d1 = new TPolyLine3D(6);
   pl3d1->SetPoint(0, 10, 20, 10);
   pl3d1->SetPoint(1, 15, 15, 15);
   pl3d1->SetPoint(2, 20, 20, 20);
   pl3d1->SetPoint(3, 20, 10, 20);
   pl3d1->SetPoint(4, 10, 10, 20);
   pl3d1->SetPoint(5, 10, 10, 10);
   // Create a first PolyMarker3D
   TPolyMarker3D *pm3d1 = new TPolyMarker3D(9);
   pm3d1->SetPoint( 0, 10, 10, 10);
   pm3d1->SetPoint( 1, 20, 20, 20);
   pm3d1->SetPoint( 2, 10, 20, 20);
   pm3d1->SetPoint( 3, 10, 10, 20);
   pm3d1->SetPoint( 4, 20, 20, 10);
   pm3d1->SetPoint( 5, 20, 10, 10);
   pm3d1->SetPoint( 6, 20, 10, 20);
   pm3d1->SetPoint( 7, 10, 20, 10);
   pm3d1->SetPoint( 8, 15, 15, 15);
   pm3d1->SetMarkerSize(2);
   pm3d1->SetMarkerColor(4);
   pm3d1->SetMarkerStyle(2);
   // Draw
   pl3d1->Draw();
   pm3d1->Draw();
}

Several coordinate systems are available:

Cartesian
Polar
Cylindrical
Spherical
PseudoRapidity/Phi

Creates a 3-D view in the current pad rmin[3], rmax[3] are the limits of the object depending on the selected coordinate system

Before drawing a 3-D object in a pad, a 3-D view must be created. Note that a view is automatically created when drawing legos or surfaces.

The coordinate system is selected via system:

system = 1 Cartesian
system = 2 Polar
system = 3 Cylindrical
system = 4 Spherical
