Choosing active range of electrodes for hitting and secondaries.


In both CPO2D and CPO3D there are options for stopping a ray when it hits an electrode and for creating a ‘secondary’ ray whenever an electrode is hit by a ‘primary’ ray.


In both these options it is possible to restrict the number of electrodes that are active.


For example you might want some electrodes to stop rays while other electrodes let rays pass through.

Or if secondaries are being created when an electrode is hit you might want some electrodes to be active while others are inactive.


The electrodes are of course defined by their segments.


Go to Databuilder/Tracing the rays/Ray limits (at the bottom of the screen) to set the lower and upper limits of the numbers of the segments that constitute the active electrodes.
