Line Members


The Line type exposes the following members.

Methods

Name Description
Public method Clone
Returns a copy of this curve.
(Inherited from Curve .)
Public method ComputeClosestPoints
Find the closest points between two curves. Closest points mean closest pairs of points, each pair consisting of a point on this, say P1, and a point on other curve, say P2. P1 and P2 are closest locally. Each pairs of closest points will be represented by the corresponding parameter values with respect to the two curves and the 3d points. A closest pair is also known as a pair of critical points of the distance function between points of the two curves. If the input parameter returnAllCriticalPoints is set to false, then the function will return only pairs with minimum distance.
(Inherited from Curve .)
Public method ComputeDerivatives
Returns the vectors describing the curve at the specified parameter.
(Inherited from Curve .)
Public method ComputeNormalizedParameter
Computes the normalized curve parameter from the raw parameter.
(Inherited from Curve .)
Public method ComputeRawParameter
Computes the raw parameter from the normalized parameter.
(Inherited from Curve .)
Public method Static member CreateBound
Creates a new instance of a bound linear curve.
Public method CreateOffset
Creates a new curve that is an offset of the existing curve.
(Inherited from Curve .)
Public method CreateReversed

(Inherited from Curve .)
Public method CreateTransformed
Crates a new instance of a curve as a transformation of this curve.
(Inherited from Curve .)
Public method Static member CreateUnbound
Creates a new instance of an unbound linear curve.
Public method Dispose
Causes the object to release immediately any resources it may be utilizing.
(Inherited from APIObject .)
Public method Distance
Returns the shortest distance from the specified point to this curve.
(Inherited from Curve .)
Public method Equals
Determines whether the specified Object is equal to the current Object .
(Inherited from GeometryObject .)
Public method Evaluate
Evaluates and returns the point that matches a parameter along the curve.
(Inherited from Curve .)
Public method GetEndParameter
Returns the raw parameter value at the start or end of this curve.
(Inherited from Curve .)
Public method GetEndPoint
Returns the 3D point at the start or end of this curve.
(Inherited from Curve .)
Public method GetEndPointReference
Returns a stable reference to the start point or the end point of the curve.
(Inherited from Curve .)
Public method GetHashCode
Gets the integer value of the geometry object as hash code
(Inherited from GeometryObject .)

Gets the Type of the current instance.
(Inherited from Object .)
Public method Intersect(Curve)
Calculates the intersection of this curve with the specified curve.
(Inherited from Curve .)
Public method Intersect(Curve, IntersectionResultArray )
Calculates the intersection of this curve with the specified curve and returns the intersection results.
(Inherited from Curve .)
Public method IsInside(Double)
Indicates whether the specified parameter value is within this curve's bounds.
(Inherited from Curve .)
Public method IsInside(Double, Int32 )
Indicates whether the specified parameter value is within this curve's bounds and outputs the end index.
(Inherited from Curve .)
Public method MakeBound
Changes the bounds of this curve to the specified values.
(Inherited from Curve .)
Public method MakeUnbound
Makes this curve unbound.
(Inherited from Curve .)
Public method Project
Projects the specified point on this curve.
(Inherited from Curve .)
Public method SetGraphicsStyleId

(Inherited from Curve .)
Public method ToString
Returns a string that represents the current object.
(Inherited from Object .)
