    Lightbulb Feature Request: New Vector drawing mode "Spiro"

    We all know, that Xara Xtreme is an easy to learn tool. But some of us are asking for new vector functions. This feature request is about such a new vector function: Simplify the process for drawing beautiful curves.

    What means "beautiful" in this case? And how could someone simplify the drawing process of such curves?

    The answer comes from the libspiro website:
    "Using bézier splines an artist can easily draw curves with the same slope on either side of an on-curve point. Spiros, on the other hand, are based on clothoid splines which make it easy to maintain constant curvature as well as constant slope. Such curves will simply look nicer.

    Raph Levien's spiro splines only use on-curve points and so are easier to use and more intuitive to the artist." [1]

    This sounds interesting and supports the claim, that Xara Xtreme is one of the fastest and easiest to learn Vector Graphics editor. And it sounds not only interesting, it is also interesting to see how it works and what kind of results are possible:


    Raph Levien, a maintainer of Ghostscript, has created the Library libspiro, which is licensed as GPL.

    So, Xara developers, what do you think: Is it worth to implement?

    That video won't play on any of my players. Not Windows media player, not Quicktime player, not Camtasia player!

    Andy, I couldn't get it to play straight off. Click on the monitor image, wait a bit & then hit the play button. Very user unfriendly!

    Remi, thanks for the link. That's the sexiest vector tool I've seen in ages plus it's so practical.

    YES PLEASE!

    Wow!

    Reminds me a bit of b-splines or splines but seems like an even better formula.
    That would be awesome in Xara!

    I agree intensley

    Spiro+Clipboard 'brushes' would be an excellent tool for drawing new vehicle striping designs.

    I second this request. That is a beautiful line! Even better than the B-Spline tool of Expression, exquisite.

    I like the look of live path effects too.
