## This macro generates two views of the NA49 detector.
##
## To have a better and dynamic view of any of these pads,
## you can click with the middle button of your mouse to select it.
## Then select "View with x3d" in the VIEW menu of the Canvas.
## Once in x3d, you are in wireframe mode by default.
## You can switch to:
##  - Hidden Line mode by typing E
##  - Solid mode by typing R
##  - Wireframe mode by typing W
##  - Stereo mode by clicking S (and you need special glasses)
##  - To leave x3d type Q
