Hello. I have an idea for generating and morphing vector shapes using bezier curves and a turtle drawing routines. You can view this as an applet here:
http://myweb.tiscali.co.uk/oaktree/jcb/applets/polymorphapplet.html
You will have to play around with the various sliders, combo boxes etc to get a feel of how the thing works. Un-check the "Skeleton" and "Control Point" boxes to see the bezier curve only.
Just thought I'd throw it into the inkscape pot. Thanks for your time.

Hi Jemima,
Would you mind posting some screenshots of this, for those of us that don't have Java installed?
THanks, Bryce
Hello again,
My email has been up the creek recently and I've lost some messages. But thanks to all who responded to my original post.
I recall one developer asking if PolyMorph might generate security watermarks (as depicted on banknotes, for example). I have modified the applet to include the PolySpi module which can generate these forms. Play around with the CP Angle decay slider to get a decent effect. I will be adding other modules in the future.

A nice toy, thanks! After playing with it a bit, I'd say that with symmetry=1, it would be a good generalization of our Star tool which already uses a similar (but simpler) approach. Higher symmetries look like they can be done in Inkscape using clones of a single star.
Hello Bulia,
Thanks for your reply. I prefer to generate symmetry procedurally using the turtle. You can download some PolyMorph PostScript output saved as PDF's here:
http://myweb.tiscali.co.uk/oaktree/jcb/applets/PolyMorph-Samples.zip
These give you an idea of what such a tool might be useful for; all were morphed from stars, spirographs, shells etc. Some are of well known fractal shapes.

Antialiasing in Java is one line of code, you know.
((java.awt.Graphics2D) g).setRenderingHint(java.awt.RenderingHints.KEY_ANTIALIASING, java.awt.RenderingHints.VALUE_ANTIALIAS_ON);

My 0.02$ : the above is already an issue with current (rounded) stars. While it gives results that are pleasant to look at and demonstrate, it is quite difficult to use as a tool - I mean, to use as an instrument to achieve a specific result one may have in mind. The possibility of spectacular results should not hide the need for proper controllers.
Kaleidoscopes are lovely, and the ineffable way the image reacts to user motion in a kaleidoscope makes them quite fascinating. But while tempting, to just fit sliders to parameters of the shaping algorithm is being overly lazy on the UI design side, imo.
What sort of control points we would want for that sort of figure, that's a topic for study and/or experimenting. Maybe what's needed is (to think of) ways to allow the user to stipulate herself (the behavior of) useful control points according to her varying needs.
Best regards, BB

Not to say that the applet doesn't go any step in that direction. Bringing the "symmetry" parameter down to its minimum of 1, does much to make the applet's (choice of) controls and essential function more intelligible. Nevertheless, I would argue that things would be just perfect if Inkscape had a architecture that allowed to plug in (and thus also retract) variations of such a thing with controls that can (in that context) be a bit arbitrary or experimental, while in the case of "core integration" more thought should be given to a right choice/system of controls.
Cheers, BB
