Talk:Find the intersection of a line with a plane

From Rosetta Code

How is this to be done?[edit]

I think this should be a draft task as there seems to be nothing in the description about how to complete the task in a comparable manner. --Paddy3118 (talk) 09:45, 15 April 2018 (UTC)

A more general case should be added[edit]

such as:
E: n=(1,2,3) P=(3,3,3)
g: A=(0,2,4) v=(3,2,1)

Java output for special cases[edit]

I tested some special cases:

If the ray is parallel to the plane:
        Vector3D rv = new Vector3D(1.0, 1.0, 0.0);
        Vector3D rp = new Vector3D(0.0, 0.0, 1.0);
        Vector3D pn = new Vector3D(0.0, 0.0, 3.0);
        Vector3D pp = new Vector3D(0.0, 0.0, 0.0);
The ray intersects the plane at (-Infinity, -Infinity, NaN)
REXX: Line is parallel to the plane

If the ray is within the plane:
        Vector3D rv = new Vector3D(1.0, 1.0, 0.0);
        Vector3D rp = new Vector3D(1.0, 1.0, 0.0);
        Vector3D pn = new Vector3D(0.0, 0.0, 3.0);
        Vector3D pp = new Vector3D(0.0, 0.0, 0.0);
The ray intersects the plane at (NaN, NaN, NaN)
REXX: Line is part of the plane

How could that be improved? ..Walter Pachl 18:16, 18 November 2018 (UTC)
