Connecting points to produce curve ?

...Bezier or other representations; is this a possibility?

Btw, as it's my first post, I want share my thanks and thoughts:

Nodebox 3 is wonderful - thank you for your thoughtful work!
Once I grasped the intended use of lists and list-operators, I came to understand the power that was open to me.
I think you've struck a useful balance between the complexities that arise both from a too 'low-level' or too generalized approach to node based programming.

    Hi,

    Welcome to the NodeBox community. I've been addicted for about nine months now and agree that NodeBox strikes the right balance; it's deceptively simple and surprisingly powerful. Lots of fun too!

    There are several ways of producing curves. The Quad Curve node draws a quadratic bezier between any two points, good for parabolas.

    Strangely, even though internal NodeBox curves are built out of cubic beziers, there is no cubic bezier node. But for rounder curves you can often make do with the arc tool. To create a curve (instead of pie chart wedge), set its Type property to Open and attach a colorizer node. Set the colorizer Fill to transparent (alpha of zero) and set the Stroke Width to something greater than zero.

    I hope that helps. If you create anything cool, please post it to the Show Your Work forum. The documentation is pretty sparse so feel free to ask (and answer) questions; we NodeBoxers have to stick together!

    John

    Thanks kindly for your considered reply John.

    I should have been more clear to specify - 3 or more points.

    Ill see if I can implement it as a custom python node.

    Cheers
