Hello visad users,
I'm a newbie.
I've been following through Ugo Taddei's VisAD Tutorial. In section 4.3 of
the tutorial, it discusses an example where, among other things, a color
and height mapped image of a matrix is obtained. I decided to substitute my
own matrix and the resulting image didn't look like what I expected. So I
decided to test things with an identity matrix instead. I expected to see a
ridge along the diagonal. Instead I obtained a series of peaks (going to 1)
and valleys (going to zero) along the diagonal. There are 5 peaks and 4
valleys. I've obtained the same results with both Java3D 1.2.2 and 1.3.
Interestingly, if I comment out the line which adds the altitude map to the
display, the resulting flat display is appropriately color mapped along the
diagonal as I would expect. So whatever "problem" I'm having seems to be
only in the z-mapping.
Are my assumptions about what I should expect correct? Any suggestions
about what may be occurring would be greatly appreciated.
Thanks in advance.
Wallace George
PS: I'm using Windows NT 4.00 (service pack 5 I think) and the latest
version of visad.
