I'm looking for a way to decide whether a point is on, to the left, or to the right of a plane. I have it to work for a selected point. For example, given a number of (x,y,z) coordinates, I'm able to determine what points are on, or across the a line drawn from a point say x = 3. The code I developed works perfect. However, I want to expand on this so that any plane can be used not just the yz plane (x = 3). I want to do a batch check on all the points in a variable called vertices. There will always be three point coordinates in this variable.
