Very nice results, Carlos!
Thanks for this helper function!

Please publish a companion example too, about how we can use such curves to drive the transition of an object along a path. Thanks in advance!

Wow just the line stuff on it’s own is cool and when you add that your doing this on a mobile device with a easy to use API it’s just sweet! Thanks for sharing now get the code out there for us!:)

Great stuff, carlos! Can’t wait to see the sample codes, etc.

need to clean up the code a bit and above all comment the part that really matters. all the other routines, the reparametization, newtonrapsody leas squares, etc. don’t really need to be documented, but the part where you pass in the points, and the err tolerance has to be neatly documented and I also need a way to pass back an array of handles. which right now works, but is not intuitive. the idea would be you pass in an array of points, and it will return you an array (or in lua lingo a table) with the points to the Bezier Curve. after that, you can do what ever you would like with the points. Draw them, or use them to ‘walk’ an object along the t values. I am also looking at implementing at reparametirizing the resulting segment…

@Carlos, what is the status of posting this sample code? It has been two and half months, it doesn’t have to be perfect it just needs to work.

Curvefitting is being added as part of the framework. That’s why it is taken longer. The C++ code shows a discernible performance increase.
