Syntax

public abstract class BoundedCurve : Curve, ICurve, ITransformable<Curve>, IBoundedCurve

Fields

DefaultMinimumChordLength

The minimum chord length allowed for subdivision of the curve. A smaller MinimumChordLength results in smoother curves. For polylines and polygons this parameter will have no effect.

Declaration

public const double DefaultMinimumChordLength = 0.1

Field Value

Type	Description
System.Double

Properties

Domain

The domain of the curve.

Declaration

[JsonIgnore]
public virtual Domain1d Domain { get; }

Property Value

Type	Description
Domain1d

End

The end of the curve.

Declaration

public virtual Vector3 End { get; protected set; }

Property Value

Type	Description
Vector3

IsClosedForRendering

Should the curve be considered closed for rendering? Curves marked true will use LINE_LOOP mode for rendering. Curves marked false will use LINE_STRIP for rendering.

Declaration

[JsonIgnore]
public virtual bool IsClosedForRendering { get; }

Property Value

Type	Description
System.Boolean

Start

The start of the curve.

Declaration

public virtual Vector3 Start { get; protected set; }

Property Value

Type	Description
Vector3
