The 3D axis painter class
==========================
This class provide up to 3 axice to any 3D ROOT plot and
"ZOOM" service.
ExecuteEvent() method does provide zooming and moving a projection
3D object within TPad client area. With Zoom mode on the user can access
TAxis3D context menu and set /change the attributes of axice all together
or separately.
To add the 3D rulers to any 3D view one has to create
an instance of this class and Draw it.
TAxis3D rulers;
rulers.Draw();
One can use a static method to create ruler and attach it to the current gPad
TAxis3D::ToggleRulers(); // Brings the 3D axice up
TAxis3D::ToggleRulers(); // next calls remove the rulers from the TPad etc
To activate Zoomer one may call
TAxis3D::ToggleZoom();
each time one needs move or zoom the image. Then the user can:
- move:
- zoom:
its 3D view with <left-mouse button> press / move.
The "Zoom" deactivates itself just the user release the <left-mouse button>
To change attributes of the rulers attached to the current Pad, one may
query its pointer first:
TAxis3D *axis = TAxis3D::GetPadAxis(); // Ask axis pointer
if (axis) {
TAxis3D::ToggleRulers() // To pop axice down
axis->SetLabelColor(kBlue); // Paint the axice labels with blue color
axis->SetAxisColor(kRed); // Paint the axice itself with blue color
TAxis3D::ToggleRulers() // To pop axice up
}
The attributes of the created axice are affected by the current style
(see TStyle class ) and Set... methods of this class
For example:
gStyle->SetAxisColor(kYellow,"X");
gStyle->SetAxisColor(kYellow,"Y");
gStyle->SetAxisColor(kYellow,"Z");
gStyle->SetLabelColor(kYellow,"X");
gStyle->SetLabelColor(kYellow,"Y");
gStyle->SetLabelColor(kYellow,"Z");
TAxis3D::ToggleRulers();
TAxis3D::ToggleRulers();
will draw all axice and labels with yellow color.

Turn ON / OFF the "Ruler", TAxis3D object attached to the current pad
Turn ON / OFF the "Ruler" and "zoom mode" of the TAxis3D object attached to the current pad (if pad = 0; gPad is used "by default") User is given a chance to either: 1. move the center of the 3D scene at the cursor position 2. zoom view with mouse "drugging" the bounder rectangle with "left" mouse 3. Change the axuce attributes via TContextMenu with "righ mouse button click"
