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.
