[...] this is a comparison between the 3 types I’ve implemented ; Cubic, CatmullRom and Cardinal. I had already addressed the topic in 2D here. a good thing with these curves is that they’re N dimensional, understand that if you find [...]

Nice, it should have been usefull in the drawing application I developped in the past.
I don’t look the source, I need to keep my mind safe. ;-) (too much maths break it)

Good job !

I'm curious what a "tutorial about the ins and outs of a concept" would look like :) if I'm not (at all) involved in the livebrush project, I have nothing against promoting it. to be fair, I should also mention psykopaint, artionscript and of course the aviary suite ;)

It would be nice if you write a tutorial about the idea behind the smooth brushes in the livebrush Air application http://www.livebrush.com/

@gregory I’ve added a checkbox next to each curve type ; it is a ‘loop’ boolean. I’ve also updated the zip
it doesn’t update systematically though… don’t know why really ; it should. the easiest is to change the precision after checking unchecking the loop mode

@makc yup, it should be fixed in the last version now it’s the Cubic path turn to do this ^^.. fix later, going home.

in addition, both “cardinal” and “catmull” do not draw very last segment

Didn’t have the time to read through the source yet, only played with it.

Does the Catmull-Rom renderer render closed curves on purpose?
