I am working with 3d point cloud data and interested in graphically selecting regions of interest from MATLAB figures. A possible scenario could be changing the view to one of the planes (e.g. XY plane) and drawing some contours or geometric shapes using cursor as shown below. Then selected datapoints should be stored in a workspace variable.
I found something similar for images (2d figures) but not sure how to that for 3d point cloud data.
Is something like this can be done in MATLAB?
