Have a look at the following message from Unidata's VisAD-List archive:
http://www.unidata.ucar.edu/staff/russ/visad/msg02013.html
Bill's answer is at
http://www.unidata.ucar.edu/staff/russ/visad/msg02015.html
from which I got this excerpt:

_From Bill's answers, I'd say it's
visad/java3d/DefaultDisplayRendererJ3D.java
or
visad/java2d/DefaultDisplayRendererJ2D.java
according to your favourite display.
By the way, the list archive is available under
http://www.unidata.ucar.edu/staff/russ/visad/
and includes a search engine. It's worth having a look there before
posting your question to the list, although the logic dictates the
opposite: Questions posted to the list are often answered faster than I
can find the answer in the archives ;-)
> Thanks a bunch,
Your're welcome.
