Hi Brian,

The arrows have small one unit long lines on them, so they will stick out a little ways past the end of the curve. Right now there isn't any way set up to have just an arrowhead all by itself without a tail on it.


> Arrow colors different from the curves might be nice?

You could do this by setting up a style for the arrows. To do that create a style like this before the first call to UpdateDecorations() :

	var style = moi.geometryDatabase.addStyle();
	var r = 0, g = 255, b = 0;
	style.color = (r << 16) | (g << 8) | b;

	UpdateDecorations( curves, points, dirs, style );

Modify the calls to UpdateDecoration() to pass the style in, and inside UpdateDecorations() when the arrow is created set its styleIndex property like this:

					if ( arrow )
					{
				>>>>		arrow.styleIndex = style.index;
						arrow.setHitTest( false );
						dirs.addObject( arrow );
					}

Then at the bottom below the last call to UpdateDecorations do style.remove();
