Hi,
How do I create a VisADLineStripArray? I have a list of coordinates and
I want a shape that connects the dots. I have used a VisADLineArray but
I have to list each coordinate twice:
shape.coordinates = new float[] {x1,y1,z1, x2,y2,z2,
x2,y2,z2, x3,y3,z3};
Will a VisADLineStripArray allow me to do something like
shape.coordinates = new float[] {x1,y1,z1, x2,y2,z2, x3,y3,z3};
and if so, what should I use for vertexCount?
When I do the latter with vertexCount = 3, I get an error:
java.lang.NullPointerException:
at
javax.media.j3d.GeometryStripArrayRetained.setStripVertexCounts(GeometryStripArrayRetained.java:37)
at
javax.media.j3d.GeometryStripArray.<init>(GeometryStripArray.java:51)
at javax.media.j3d.LineStripArray.<init>(LineStripArray.java:60)

...
Thanks,
Doug
