Re: immersive flythrough

Hi Doug,
For a DisplayImplJ3D, double[] matrix has 16 elements and
is organized as the argument to:[] matrix)
We have recently seen the behavior you describe, where the
projection snaps back when you click the mouse.  It is caused
  ProjectionControlJ3D pc = new ProjectionControlJ3D(display);
Try this instead:
  ProjectionControlJ3D pc = display.getProjectionControl();
The next update of VisAD will test for the former and throw an
Exception (basically, you've got a DisplayImplJ3D with two
ProjectionControlJ3Ds, one for the mouse and one you control).
Good luck,
