FAQ

- What algorithm do you use to calculate the shortest distance
between two points?
You have two points ,
The distance is =.
- What algorithm do you use to calculate the point on a line
(footpoint ), that is closest to another
point, that is not on the line?
You have a point
and a line ;

- What algorithm do you use to calculate the shortest distance
between a point and a line?
I calculate the distance between the Point and the Footpoint.
(see Question before)
- What algorithm do you use to calculate the shortest distance
between two lines?
You have 2 lines: ,
If then calculate the distance
between the point and the line .
Else calculate
if not (d=0 or h=0) then the distance is d/h.
- What algorithm do you use to calculate the distance between two
vectors?
This question confuses the words "vector" and "point". A vector
has a direction and a length. A point can be describted with a
vector relative to another point. If I write only a vector for a
point, the vector describts the point relative to the zeropoint. A
distance between two vectors doesn’t make sense. It can be
compared with the distance between left and right.

points?
