In case you want to rotate the display by multiples of 90° (in whatever
direction), then consider using the method

ProjectionControlJ3D.setOrthoView(int view)

with valid views being:

  /** View of the postive X face of the display cube */
  public static final int X_PLUS = 0;
  /** View of the negative X face of the display cube */
  public static final int X_MINUS = 1;
  /** View of the postive Y face of the display cube */
  public static final int Y_PLUS = 2;

etc...

Please refer to the following message in the list archive

for more info on the subject.

Cheers,

Ugo
