Computes the parallel projection of the edge onto a plane.

Namespace: ceometric.VectorGeometry
Assembly: ceometric.VectorGeometry (in ceometric.VectorGeometry.dll) Version: 1.8.0.0 (1.8.0.0)

Syntax

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

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

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

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

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

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

Returns a zero-length edge if viewDirection is collinear to the edge.

Remarks

For an orthogonal parallel projection of an edge e onto a plane pl, write e.ProjectParallelOn(pl, pl.NormalVector);

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