Public Function ProjectParallelOn ( _ plane As Plane, _ viewDirection As Vector3d _ ) As Line |
Visual C++ |
---|
public: Line^ ProjectParallelOn( Plane^ plane, Vector3d^ viewDirection ) |
Parameters
- 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.
Return Value
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);
Exceptions
Exception | Condition |
---|---|
System..::.ArgumentException | The view direction is parallel to the projection plane. |
System..::.ArgumentException | The view direction is parallel to the line. |
