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.
