1 # Distance to Plane 2 3 Distance from arbitrary point to plane 4 5 If we take any point on the plane and then find the length of the opposite side of the new right triangle we then have the distance from the plane to the point. 6 7 As such this is as simple as taking the dot product of the normal vector and the vector that connects the representative point and the other point. We then divide this by the lenght of the normal vector and that is the lenght of the opposite side which is also the distance between the plane and the point. 8 9 To find distance to plane from point do the following: 10 11 1. Find the vector from a representative point to the point 12 2. Calculate the dot product between this vector connecting these two points and the normal vector 13 3. Divide this value by the length of the normal vector
