The cubic-bezier function is a transition timing function which is often used for custom and smooth transitions. transition-timing-function: cubic-bezier(0.1, 0.7, 1.0, 0.1); The function takes four parameters: cubic-bezier(P1_x, P1_y, P2_x, P2_y) These parameters will be mapped to points whic...

// Usage: var p0={x:50,y:100}; var p1={x:100,y:0}; var p2={x:200,y:200}; var p3={x:300,y:100}; cubicCurveArrowHeads(p0, p1, p2, p3, 15, true, true); quadraticCurveArrowHeads(p0, p1, p2, 15, true, true); // or use defaults true for both ends with arrow heads cubicCurveArrowHeads(p0, p...

This example finds an array of approximately evenly spaced points along a cubic Bezier curve. It decomposes Path segments created with context.bezierCurveTo into points along that curve. // Return: an array of approximately evenly spaced points along a cubic Bezier curve // // Attribution: Stack...

Given the 4 points of a cubic Bezier curve the following function returns its length. Method: The length of a cubic Bezier curve does not have a direct mathematical calculation. This "brute force" method finds a sampling of points along the curve and calculates the total distance spanne...

textOnCurve(text,offset,x1,y1,x2,y2,x3,y3,x4,y4) Renders text on quadratic and cubic curves. text is the text to render offset distance from start of curve to text >= 0 x1,y1 - x3,y3 points of quadratic curve or x1,y1 - x4,y4 points of cubic curve or Example usage: textOnCurve("...
