The dimension of the minor axis (Y) of the ellipse.

Ellipse(Vector3, Double, Double)

Create an ellipse.

Declaration
public Ellipse(Vector3 center, double majorAxis = 2, double minorAxis = 1)
Parameters
Type Name Description
Vector3 center

The center of the ellipse.

The dimension of the major axis (X) of the ellipse.
System.Double minorAxis

The dimension of the minor axis (Y) o the ellipse.

Properties

Center

The center of the ellipse.

Declaration
[JsonIgnore]
public Vector3 Center { get; }
Property Value
Type Description
Vector3

MajorAxis

The dimension of the major axis (X) of the ellipse.

Declaration
public double MajorAxis { get; set; }
Property Value
Type Description
System.Double

MinorAxis

The dimension of the minor axis (Y) of the ellipse.

Declaration
public double MinorAxis { get; set; }
Property Value
Type Description
System.Double

Transform

Declaration
public Transform Transform { get; protected set; }
Property Value
Type Description
Transform

Methods

ParameterAtDistanceFromParameter(Double, Double)

Get the parameter at a distance from the start parameter along the curve.

Declaration
public override double ParameterAtDistanceFromParameter(double distance, double start)
Parameters
Type Name Description
System.Double distance

The distance from the start parameter.
System.Double start

The parameter from which to measure the distance.
Returns
Type Description
System.Double
Overrides

PointAt(Double)

Get a point along the ellipse at parameter u.

Declaration
public override Vector3 PointAt(double u)
Parameters
Type Name Description
System.Double u
Returns
Type Description
Vector3

A point on the ellipse at parameter u.
Overrides

TransformAt(Double)

Get a transform along the ellipse at parameter u.

Declaration
public override Transform TransformAt(double u)
Parameters
Type Name Description
System.Double u
Returns
Type Description
Transform

A transform on the ellipse at parameter u.
Overrides

Transformed(Transform)

Create a transformed copy of this curve. Use of non-affine transforms (i.e. scale) will result in unpredictable results for curve methods such as Length().

Declaration
public override Curve Transformed(Transform transform)
Parameters
Type Name Description
Transform transform

The transform to apply.
Returns
Type Description
Curve
Overrides
