Find a point, a given distance, along a simple cubic bezier curve. (On an iPhone!)

Imagine you have a completely normal four-point bezier curve (two points and two control points) created using curveToPoint:controlPoint1:controlPoint2: in your cocoa application:[详细]

Bezier curves algorithm - maybe Canonical Splines?

I\'ve got a path that is made up of multiple points - i.e. 0,00,5050,5070,20 If I just draw this line on the screen it looks quite harsh as it puts a sharp angle at the joining of each point.[详细]

Creating a "fractional" bezier spline?

I have a 4-control-point bezier curve that represents some timing stuff. The first control is fixed at (0, 0) and the last control is fixed at (1, 1). The two points in between define a bezier curve t[详细]
