Detailed Description

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
