How do you make a bezier curve that you can move points around to edit it?
There isn't a Bezier feature in the paint editor, if that's what you're asking. Someday.
i ment a renderer, im making a custom vector editor
Ah. Not a graphics expert, sorry. Jens? Bernat? Joachim?
Bezier curves are kind of tricky, but this article did a good job explaining them.
i still dont know how to do it
I love bezier curves, but the thing is, you'd need a PJS code or block, and I dunno if you can use PJS in the Snap! code editor yet.
Correct me if I'm wrong-
What do you mean by PJS?
And I thought you in school... How do you have time on snap?
I am. I have a class that makes me code on Snap.
Ohhhhhh so you do have CS
There can be only one type of Processing JS(at least I think), It's all the same thing. Just many websites.
Hmm I see:
- a github repo
- happy coding
which one is it?
that one, I'm sure.
hmm ok hey what a coincedence I have CS today too
or you can just make your own beizer curve block/method
i think (for a 3-point beizer curves) it works by using linear interpolation, you use lerp to get a point between the line between p1 and p2 and the line between p2 and p3, then you create a line between those two points and use lerp to a get a point in that line which is a point in the beizer curve
https://snap.berkeley.edu/snap/snap.html#present:Username=spaceelephant&ProjectName=besier%20curves might help. It uses a recursive helper for each point, and then combines those.
