Dears,

I’m trying to identify the points are in the left and right side of a line.

You could watch what I’m trying to do in that instance.

What I’m thinking consist of getting a normal vector from the line to all points. Vectors are positive, points are on the right side, vectors are negative, points are on the left side.

With de negative or positive vector to each point it could be easy to filter the points.

But, how could I calculate a normal vector between the line and points, and identify which one is negative or positive.

Regards,
