setAspect on 3D display

Hi Everybody,

I'm trying to get some deformations on my 3D display axes but it seems like I'm doing something wrong. Here it goes what I'm doing:

ProjectionControl pcDEM = displayDEM.getProjectionControl();
pcDEM.setAspect(new double[] {1.0, 0.5,1.0});

Where displayDEM is a DisplayImplJ3D.

I assumed this approach was OK since I have successfully used

ProjectionControl pcDEM = displayDEM.getProjectionControl();
pcDEM.setAspect(new double[] {1.0, 0.5});

where displayDEM is a DisplayImplJ2D.

Does setAspect method works differently on a 3D display?

Thanks,

Ricardo
