See http://www.ssec.wisc.edu/~billh/visad_archive/msg02758.html

You need to add a DisplayListener to your DisplayImpl, and
look for DisplayEvents with getId() equal to the appropriate 
MOUSE_PRESSED, MOUSE_PRESSED_CENTER, etc. Then call getX()
and getY() to get the mouse coordinates.

Also look into using visad/bom/PointManipulationRendererJ3D.java
which can give you mouse right-button click location in data
coordinates. You can easily construct RealTuple objects from
those coordinates.

Good luck,
Bill
