Get a list of coordinates 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 interested to know the position on the curve given a parameter, use BezierCurve:evaluate.
Contents
Function
Synopsis
coordinates = BezierCurve:render(depth)
Arguments
number depth (5)- Number of recursive subdivision steps.
Returns
table coordinates- List of x,y-coordinate pairs of points on the curve.
Example
Draw a bezier curve
curve = love.math.newBezierCurve({25,25,75,50,125,25})
function love.draw()
love.graphics.line(curve:render())
end
