I have just started using VisAD and after coding
up my first application, have run into two problems.
1) The image shows up as a set of thin lines, i.e. the pixels
are not filled in. Perhaps I am using the wrong rendering
or data type ... ?
My math type is:
(radial, gate) --> (x,y,z, value)
and I am displaying using the java 3D display
with x as Display.XAxis, etc. and value as Display.RGBA
I also tried using the FlowSpherical coordinate transform
instead of explicitly providing x,y,z but I get the same result.
I would like a textured image ... (I did the setTextureEnable
without any effect).
2) I saw on the list that Don Murray suggested using a set of numbers
and explicitly assigning colors to get discrete colors for a
continuous field. The problem is that my data are floating point
values, and so I can not really come up with exact
numbers for a color table.
So, I used a FlatField and the setFunction method.
How do I tell the FlatField that the data should be
NEAREST_NEIGHBOR and not WEIGHTED_AVERAGE?
thanks
