Figuring I'm not the only one who wants to be able to return the VisAD
display cube to it's original position, size, and orientation, here's
how to do it.
double[] pcMatrix;
.....
di = new DisplayImplJ3D("display1");
pc = di.getProjectionControl();
pcMatrix = pc.getMatrix();
and then whenever you want to have the cube reset, just:
pc.setMatrix(pcMatrix);
(In my application, this was the action for a button in the GUI
so the user could return to a set view.)
Also, if you'd like to force the cube to be a different size, you can
rescale it; right after the "pc.getMatrix()" call, do this:
pcMatrix[0] = scale;
pcMatrix[5] = scale;
pcMatrix[10] = scale;
where a value of .9 scales it to occupy 90% of the size of the display
window.
