Hi:
I'm getting the following error and I cannot figure out why:
Exception occurred during event dispatching:
java.lang.NullPointerException
at
javax.media.j3d.GeometryArrayRetained.setCoordinates(GeometryArrayRetained.java:
2680)
at javax.media.j3d.GeometryArray.setCoordinates(GeometryArray.java:976)
at jdend$jdendShape.initCentroidRender(jdend.java:921)
I've looked at my code over and over, added print statements to look at
values, and looked at sample sources using PointArray and still cannot figure
out what I am doing wrong.
Here are some code excerpts along with their associated line numbers:
845 Point3d[] centroids;
846 PointArray dots;
...
867 centroids = new Point3d[object_data.size()];
...
893 centroids[planei] = trace_data.centroid3D();
...
920 dots = new PointArray ( centroids.length,
PointArray.COORDINATES );
921 dots.setCoordinates ( 0, centroids );
All help and pointers are greatly appreciated.
Sincerely,
Mona
