I\'ve 开发者_StackOverflowcreated a \"blob\" shape by patching cubic Bezier curves together (screenshot below).I\'d like to be able to detect the situation where a curve has crossed over either itself
HI all - I am using anchor points and control p开发者_Go百科oints to create a shape using curveTo. It\'s all working fine, but I cannot figure outhow to get my lines to go through the center of the c
Having searched the web, I see various people in various forums alluding to approximating a cubic curve with a quadratic one. But I can\'t find the formula.
I\'m trying to define a path of points.Each point has an x, y, and time.I then want to query this path and get the current position at that point in time.Let me share some pseudo code.
I\'m definetely new to any kind of开发者_开发技巧 graphics (maybe except taking photos :)) so please forgive if my explanation of problem I faced last night is not very precise and understable.
We have a start point (x, 开发者_C百科y) and a circle radius. There also exists an engine that can create a path from Bézier curve points.
I needed to find and use the coordinates of the intersection of a cubic Bezier and a straight line. The trouble is that I c开发者_Python百科annot find a non-parametric representation of a Bezier curve
