Hi There! I have got two objects. I have got a Planemodel that represents a plane with a certain orientation in a certain place like so:

plane = planeModel([0 0 1 1]);

as well as a pointCloud like so:

load('object3d.mat');

I'm looking for a way to calculate the distance between the plane and the points in the point cloud, where points on one side of the plane get a positive and the other side a negative distance.

I just want to add this: https://de.mathworks.com/matlabcentral/fileexchange/62096-point-plane-distance?focused=7396450&tab=function I found it after a lot more searching online, maybe it will help others who stumble across my question here.
