'Clickable' 'zoomable' 2D Boolean Control. Example of a 2D control that populates a 2D array. Would like to promote the idea of 3D controls that users can populate with 3D lines in space, and either output the line equation or define by points to populate a 3D array for subsequent use in program code. Controls that a user can manipulate with the mouse by clicking or dragging handles would be very useful in a number of laboratory applications. Would like to have the ability to import lines/shapes from simple text files, etc., and anchor points/lines i.e. constrain axes, etc. to help manipulate the shapes.
