[page:CurvePath] →

[name]

A 2D path representation. The class provides methods for creating paths and contours of 2D shapes similar to the 2D Canvas API.

Example

var path = new v3d.Path(); path.lineTo(0, 0.8); path.quadraticCurveTo(0, 1, 0.2, 1); path.lineTo(1, 1); var points = path.getPoints(); var geometry = new v3d.BufferGeometry().setFromPoints(points); var material = new v3d.LineBasicMaterial({ color: 0xffffff }); var line = new v3d.Line(geometry, material); scene.add(line);

Constructor

[name]([param:Array points])

points -- (optional) array of [page:Vector2 Vector2s].

Creates a Path from the points. The first point defines the offset, then successive points are added to the [page:CurvePath.curves curves] array as [page:LineCurve LineCurves].

If no points are specified, an empty path is created and the [page:.currentPoint] is set to the origin.

Properties

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

[property:array currentPoint]

The current offset of the path. Any new [page:Curve] added will start here.

Methods

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

[method:null absarc]([param:Float x], [param:Float y], [param:Float radius], [param:Float startAngle], [param:Float endAngle], [param:Float clockwise])

x, y -- The absolute center of the arc.
radius -- The radius of the arc.
startAngle -- The start angle in radians.
endAngle -- The end angle in radians.
clockwise -- Sweep the arc clockwise. Defaults to *false*.

Adds an absolutely positioned [page:EllipseCurve EllipseCurve] to the path.

[method:null absellipse]([param:Float x], [param:Float y], [param:Float xRadius], [param:Float yRadius], [param:Float startAngle], [param:Float endAngle], [param:Float clockwise], [param:Float rotation])

x, y -- The absolute center of the ellipse.
xRadius -- The radius of the ellipse in the x axis.
yRadius -- The radius of the ellipse in the y axis.
startAngle -- The start angle in radians.
endAngle -- The end angle in radians.
clockwise -- Sweep the ellipse clockwise. Defaults to false.
rotation -- The rotation angle of the ellipse in radians, counterclockwise from the positive X axis. Optional, defaults to 0.

Adds an absolutely positioned [page:EllipseCurve EllipseCurve] to the path.

[method:null arc]([param:Float x], [param:Float y], [param:Float radius], [param:Float startAngle], [param:Float endAngle], [param:Float clockwise])

x, y -- The center of the arc offset from the last call.
radius -- The radius of the arc.
startAngle -- The start angle in radians.
endAngle -- The end angle in radians.
clockwise -- Sweep the arc clockwise. Defaults to *false*.

Adds an [page:EllipseCurve EllipseCurve] to the path, positioned relative to [page:.currentPoint].

[method:null bezierCurveTo]([param:Float cp1X], [param:Float cp1Y], [param:Float cp2X], [param:Float cp2Y], [param:Float x], [param:Float y])

This creates a bezier curve from [page:.currentPoint] with (cp1X, cp1Y) and (cp2X, cp2Y) as control points and updates [page:.currentPoint] to x and y.

[method:null ellipse]([param:Float x], [param:Float y], [param:Float xRadius], [param:Float yRadius], [param:Float startAngle], [param:Float endAngle], [param:Float clockwise], [param:Float rotation])

x, y -- The center of the ellipse offset from the last call.
xRadius -- The radius of the ellipse in the x axis.
yRadius -- The radius of the ellipse in the y axis.
startAngle -- The start angle in radians.
endAngle -- The end angle in radians.
clockwise -- Sweep the ellipse clockwise. Defaults to *false*.
rotation -- The rotation angle of the ellipse in radians, counterclockwise from the positive X axis. Optional, defaults to *0*.

Adds an [page:EllipseCurve EllipseCurve] to the path, positioned relative to [page:.currentPoint].

[method:null lineTo]([param:Float x], [param:Float y])

Connects a [page:LineCurve] from [page:.currentPoint] to x, y onto the path.

[method:null moveTo]([param:Float x], [param:Float y])

Move the [page:.currentPoint] to x, y.

[method:null quadraticCurveTo]([param:Float cpX], [param:Float cpY], [param:Float x], [param:Float y])

Creates a quadratic curve from [page:.currentPoint] with cpX and cpY as control point and updates [page:.currentPoint] to x and y.

[method:null setFromPoints]([param:Array vector2s])

points -- array of [page:Vector2 Vector2s].

Points are added to the [page:CurvePath.curves curves] array as [page:LineCurve LineCurves].

[method:null splineThru] ([param:Array points])

points - An array of [page:Vector2 Vector2s]

Connects a new [page:SplineCurve] onto the path.
