Computes the parallel projection of the line onto a plane.

Namespace: ceometric.VectorGeometry
Assembly: ceometric.VectorGeometry (in ceometric.VectorGeometry.dll) Version: 1.6.0.0 (1.6.0.0)

Syntax

C#
public Line ProjectParallelOn( Plane plane, Vector3d viewDirection )

Visual Basic (Declaration)
Public Function ProjectParallelOn ( _ plane As Plane, _ viewDirection As Vector3d _ ) As Line

Visual C++
public: Line^ ProjectParallelOn( Plane^ plane, Vector3d^ viewDirection )

plane: Type: ceometric.VectorGeometry..::.Plane
A plane the line is projected onto.

viewDirection: Type: ceometric.VectorGeometry..::.Vector3d
A vector defining the direction of the projection.

Returns the parallel projection of the line onto plane in the direction of viewDirection.

Remarks

For a perpendicular projection of a line l onto a plane pl, write l.ProjectParallelOn(pl, pl.NormalVector);

Exception	Condition
System..::.ArgumentException	The view direction is parallel to the projection plane.
System..::.ArgumentException	The view direction is parallel to the line.
