Methods

CompareTo

#
public int CompareTo(SplineHandle other)
Comparer only considers grip locations. Tangents are ignored. This is useful for sorting grips.
Parameters:
other (SplineHandle)Grip to compare to.
Returns: Comparison order.

CreateCusp

#
public static SplineHandle CreateCusp(Point2d point, Vector2d incoming, Vector2d outgoing)
Create a discontinuous spline handle with two tangent constraints.
Parameters:
point (Point2d)
incoming (Vector2d)
outgoing (Vector2d)

CreateNatural

#
public static SplineHandle CreateNatural(Point2d point)
Create a natural spline handle without tangent constraints.
Parameters:
point (Point2d)

CreatePlanar

#
public static SplineHandle CreatePlanar(Point2d point)
Create a spline handle with a horizontal tangent constraint.
Parameters:
point (Point2d)

CreateSmooth

#
public static SplineHandle CreateSmooth(Point2d point, Vector2d tangent)
Create a continuous spline handle with a single tangent constraint.
Parameters:
point (Point2d)
tangent (Vector2d)

Equals

#
public bool Equals(SplineHandle other)
Equality only considers grip locations.
Parameters:
other (SplineHandle)Grip to compare against.
Returns: True if grips are considered equal.
