BezierCurve:renderSegment

Available since LÖVE 0.10.0
This function is not supported in earlier versions.

Get a list of coordinates on a specific part of the curve, to be used with love.graphics.line.

This function samples the Bézier curve using recursive subdivision. You can control the recursion depth using the depth parameter.

If you are just need to know the position on the curve given a parameter, use BezierCurve:evaluate.

Function

coordinates = BezierCurve:renderSegment( startpoint, endpoint, depth )

number startpoint: The starting point along the curve. Must be between 0 and 1.
number endpoint: The end of the segment to render. Must be between 0 and 1.
number depth (5): Number of recursive subdivision steps.

table coordinates: List of x,y-coordinate pairs of points on the specified part of the curve.

curve = love.math.newBezierCurve({25,25,75,50,125,25})
function love.draw()
	love.graphics.line(curve:renderSegment(0, .75))
