Hi Bill,

That seems to have done the trick!

Thanks,
Doug

Doug,

I cannot replicate the failure by running:

  java visad.bom.CurveManipulationRendererJ3D

However, I found something that might cause the behavior
you are seeing. Please test this possible fix by downloading
and compiling test versions of:

  ShadowFunctionOrSetType.java
  VisADLineStripArray.java
  VisADTriangleStripArray.java
  VisADIndexedTriangleStripArray.java

from ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/

Let me know if these fix your problem. If not, then you'll
need to send me a test program that I can use to replicate
the Exception you're seeing.

Hi,

I've been using visda.bom.CurveManuipulationRendererJ3D in my app with
success for quite some time. I just got the latest visad.jar file and
now, whenever I try to draw a curve I get:

java.lang.NullPointerException
        at
visad.VisADLineStripArray.removeMissing(VisADLineStripArray.java:469)

I suspect it was a change since the beginning of the year (2003) and I
have noticed some changelog activity in that area. Any ideas?

Thanks,
Doug
