Curve

EllipseCurve

Creates a 2d curve in the shape of an ellipse. Setting the xRadius equal to the yRadius will result in a circle.

Example

var curve = new v3d.EllipseCurve( 0, 0, // ax, aY 10, 10, // xRadius, yRadius 0, 2 * Math.PI, // aStartAngle, aEndAngle false, // aClockwise 0 // aRotation ); var points = curve.getPoints(50); var geometry = new v3d.BufferGeometry().setFromPoints(points); var material = new v3d.LineBasicMaterial({ color : 0xff0000 }); // Create the final object to add to the scene var ellipse = new v3d.Line(geometry, material);

Constructor

EllipseCurve(aX : Float, aY : Float, xRadius : Float, yRadius : Float, aStartAngle : Radians, aEndAngle : Radians, aClockwise : Boolean, aRotation : Radians)

aX – The X center of the ellipse. Default is 0.
aY – The Y center of the ellipse. Default is 0.
xRadius – The radius of the ellipse in the x direction. Default is 1.
yRadius – The radius of the ellipse in the y direction. Default is 1.
aStartAngle – The start angle of the curve in radians starting from the positive X axis. Default is 0.
aEndAngle – The end angle of the curve in radians starting from the positive X axis. Default is 2 x Math.PI.
aClockwise – Whether the ellipse is drawn clockwise. Default is false.
aRotation – The rotation angle of the ellipse in radians, counterclockwise from the positive X axis (optional). Default is 0.

Properties

See the base Curve class for common properties.

.aX : Float

.aY : Float

The Y center of the ellipse.

.xRadius : Radians

The radius of the ellipse in the x direction.

.yRadius : Radians

The radius of the ellipse in the y direction.

.aStartAngle : Float

The start angle of the curve in radians starting from the middle right side.

.aEndAngle : Float

The end angle of the curve in radians starting from the middle right side.

.aClockwise : Boolean

Whether the ellipse is drawn clockwise.

.aRotation : Float
