public Vector3d ProjectParallelOn( Plane plane, Vector3d viewDirection ) |
Visual Basic (Declaration) |

Public Function ProjectParallelOn ( _ plane As Plane, _ viewDirection As Vector3d _ ) As Vector3d |
Visual C++ |
---|
public: Vector3d^ ProjectParallelOn( Plane^ plane, Vector3d^ viewDirection ) |
Parameters
- plane
- Type: ceometric.VectorGeometry..::.Plane
A plane the 3d vector is projected onto.
- viewDirection
- Type: ceometric.VectorGeometry..::.Vector3d
A vector defining the direction of the projection.
Return Value
The projection of the vector onto plane in the direction of viewDirection.Remarks
For a perpendicular projection of a 3d vector v on a plane plane, write v.ProjectParallelOn(plane, plane.NormalVector);
If the vector and viewDirection are parallel, this method returns a zero length vector.
Exceptions

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