# Talk:Find the intersection of a line with a plane

## How is this to be done?

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

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

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)
