Re: your mail

Do you know the size (# samples in x and y) of the image/texture map that is trying to be displayed? There is an OpenGL-related issue on Windows (and perhaps other platforms) in that if the data is displayed with texture mapping (as you might with an image) and has a dimension larger than a hardware-dependent value, then it displays has a flat white or gray square. On my machine, the limit is 1024; one other machine we have here, it's 512.
The only solution I know of for the time being is to resample the data to a smaller number of samples.

Hi Curtis,

I'm actually using JCreator only to edit, but I'm compiling on the command
line and typing in java -mx512m visad.ss.SpreadSheet to run it on the
command line. I also tried adding the line

DisplayCells[0][0].setDim3D();

right before
DisplayCells[0][0].addDataSource("D:\\visad\\data\\small.v5d",
BasicSSCell.URL_SOURCE);

but I'm still getting the plain flat white square in the cell.

Hi,

If you are using some sort of development environment,
then I cannot help you, unfortunately.  The only advice
I can offer is to quit and restart the environment...

If you are using a text editor and command line (which
is what I do), then you may still have a problem with
your CLASSPATH.  I cannot think of any other reason
you'd be having trouble with versions like you are.

Since the SpreadSheet prepends "file:/" to the source
string, it looks like it's finding your file now.  If
you're getting a white, 2-D box, perhaps cell A1 is set
to 2-D mode instead of 3-D?  You can call setDimension()
on the cell to switch it to 3-D before loading the file.

Hi Curtis, Tom, and group,

I tried replacing the "\" with "\\". Now, however, a plain white 2-D square
is imported instead of the cube with the fancy representation. Also, I
originally had the file specified as
D:\\visad\\unzipped\\visad\\ss\\small.v5d and when that didn't work, I
changed it to D:\\visad\\data\\small.v5d. But when I opened up a new
instance of the spread sheet and clicked on "GO", the file that was listed
in the "ADD/DELETE" menu was A1d1:
file:/D:/visad/unzipped/visad/ss/small.v5d instead of data/small/v5d. So


I'm


thinking it is indeed running an old version of my code. I added a
system.out.println statement in my method and nothing was printed in my
shell. Do you know what I can change to get it to see the newest version of
my code?

Thanks,
