I notice that Vuforia tracks an image target even when parts of the image target is occluded (screenshot attached).
My application requires such image targets cropped and windowed in various ways.
While this is great for tracking, sometimes the overlayed geometry ends up extending outside this cropped/windowed marker. This is because, TrackableResult-> getPose() always gives us matrices that are setup for the original size of the image target and not for this cropped version.
My question is, is there a way to get from Vuforia, how much of the marker it is seeing, what are the corners for the visible regions etc? So, I can map geometries only to the visible regions rather than the size of the original image target.
(The cropping and windowing is dynamic, so I cannot pre-train to the cropped version).
