[Obsolete] Catmull-Rom Spline
-
Edit 19 Oct 08: I released a comprehensive version of BezierSpline,version 1.2, which includes this extension. It is advised to refere to the following post:
http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=13563#p100509Here is an extension to the BezierSpline plugin for drawing Catmull-Rom splines (in 3D).
You need to drop the two attached files (BZ__Catmull.rb and BZ_Catmull.png) in the BZ_Dir subfolder.As for Cubic Bezier, this type of curve passes through all the control pointsand a move of a control point will only affect the shape of the curve locallyaround this control point (exactly the portion before and the two after).
Note that it can be 'nicely' closed by a Catmull spline, not by an approximate Bezier curve, as I do for other curves.
All this said, Cubic Bezier and Catmull splines are quite close, though Catmull seems to stay closer to the polygon of control points.
Below is a comparison:

(and thanks CadFather for the icons)well, here's the set with courbette - i think BZ_divider was already included (am i wrong?)
Fredo, i tried to add/rename the icons _24 or _16 but the toolbar does not update like TOS.
if it is something you can do in some spare time it would be great (though we can still keep 2 sets one of which we just drop in the BZ folder)here they are:
