Disclaimer:  The following implies no criticism of OpenDX, I am probably
doing something stupid. 

I am having trouble visualising irregular data connected by tetrahedra.
While a couple of very simple cases work, with 1 and 6 tetrahedra, I am
unsuccessful with my real dataset.  I generate about 4500 tetrahedra from
about 2500 data points.  The program appears to be doing some computation,
and gives no errors, but the image is not visible.

I am using:

Import > Mark > MapToPlane > AutoColor > Image

I have turned up the intensity in AutoColor to 10, and I have tried looking
at the three planes through the c.g.  The same program works fine for my
simple cases.

The coordinates of my points are in the following range:

x in (299000 -> 302000)
y in (700000 -> 704000)
z in (-15 -> 3)

Is it possible that I am violating some program limits?

Alternatively, it is possible that an image is being created but I can't see
it, i.e. it is off screen.  Is there a way to make sure that the the image
is in the field of view?

Thanks for your help
