Hi,
After an intermittent 12-hr period I finally decided
to put the monkey-typewriter-shakesphere theory to
test and came up with a remedial solution, that is
line.updateData( new GeometryUpdater() {
public void updateData(Geometry g) {
g = shape3D.getGeometry();
LineArray tempLine = (LineArray) g;
tempLine = lineArray( verts2 );
shape3D.setGeometry( tempLine );
}
});
Still amazed that I had to initiate a new LineArray
but it beats the overhead of a branchGroup. If there
is a cleaner way to have done this please enlighten
me.
Thanks,
Greg.
