ProjectParallelOn Method
Computes the parallel projection of the ellipse 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 Ellipse ProjectParallelOn(
	Plane plane,
	Vector3d viewDirection
)
Visual Basic (Declaration)
Public Function ProjectParallelOn ( _
	plane As Plane, _
	viewDirection As Vector3d _
) As Ellipse
Visual C++
public:
Ellipse^ ProjectParallelOn(
	Plane^ plane, 
	Vector3d^ viewDirection
)

Parameters

plane
Type: ceometric.VectorGeometry..::.Plane
A plane the ellipse is projected onto.
viewDirection
Type: ceometric.VectorGeometry..::.Vector3d
A vector defining the direction of the projection.

Return Value

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

Remarks

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

Exceptions

ExceptionCondition
System..::.ArgumentExceptionThe view direction is parallel to the projection plane.
System..::.ArgumentExceptionThe view direction is parallel to the ellipse.
