vonWolfehaus / Line interpolation

Created September 24, 2012 16:34

Simple interpolation technique for plotting missing points between two key points

	function lineInterpolate(point1, point2, distance) {
	var xabs = Math.abs( point1.x - point2.x );
	var yabs = Math.abs( point1.y - point2.y );
	var xdiff = point2.x - point1.x;
	var ydiff = point2.y - point1.y;

	var length = Math.sqrt( ( Math.pow( xabs, 2 ) + Math.pow( yabs, 2 ) ) );
	var steps = length / distance;
	var xstep = xdiff / steps;
	var ystep = ydiff / steps;

Circle to rectangle collision detection

	// limits value to the range min..max
	function clamp(val, min, max) {
