I am trying to create a toolbox that is able to modify shapefiles.
My first approach is the existing DirectManipulationRendererJ3D, but as
I try it with the code below, it gives me:
null: DirectManipulationRendererJ3D.doTransform in the lower left corner
of the display.
_________________________________________________________
Coordinate[] tmpCoord = coords.elementAt(i);
int np = tmpCoord.length;
float[][] samples = new float[2][np];
for (int j = 0; j < np; j++) {
samples[0][j] = (float) tmpCoord[j].x;
samples[1][j] = (float) tmpCoord[j].y;
}
// the lines
Gridded2DSet tmpLines = new Gridded2DSet(earth, samples,
samples[0].length);
// create a DataReference for river system
DataReference rivers_ref = new DataReferenceImpl("rivers");
rivers_ref.setData(tmpLines);
ConstantMap[] colorMapLines = { new ConstantMap(1, Display.Red),
new ConstantMap(0, Display.Green),
new ConstantMap(0, Display.Blue),
new ConstantMap(3f, Display.LineWidth) };
display1.addReferences(new DirectManipulationRendererJ3D(),
rivers_ref, colorMapLines);

What am I doing wrong?
