[name]

Create a smooth 2d quadratic bezier curve, defined by a startpoint, endpoint and a single control point.

Example


var curve = new THREE.QuadraticBezierCurve(
	new THREE.Vector2( -10, 0 ),
	new THREE.Vector2( 20, 15 ),
	new THREE.Vector2( 10, 0 )
);

var points = curve.getPoints( 50 );
var geometry = new THREE.BufferGeometry().setFromPoints( points );

var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );

//Create the final object to add to the scene
var curveObject = new THREE.Line( geometry, material );

Constructor

[name]( [param:Vector2 v0], [param:Vector2 v1], [param:Vector2 v2] )

[page:Vector2 v0] – The startpoint.
[page:Vector2 v1] – The control point.
[page:Vector2 v2] – The endpoint.

Properties

See the base [page:Curve] class for common properties.

[property:Boolean isQuadraticBezierCurve]

Used to check whether this or derived classes are QuadraticBezierCurves. Default is *true*.

You should not change this, as it used internally for optimisation.

[property:Vector2 v0]

The startpoint.

[property:Vector2 v1]

The control point.

[property:Vector2 v2]

The endpoint.

Methods

See the base [page:Curve] class for common methods.
