Each defined perspective set can be applied to HyperDoc's Tesselets like Tree or Grid on HyperDoc main panel and users can choose which they work on.
How does a Perspective Set influence a specific TreeView Tesslet?
Image below illustrates that. Please note, that "Main Hierarchy" is selected as a perspective for this specific Tree View Tesselet.
TreeView is now instructed to load object of class Failitetere with ID "0". What objects should be loouked up and loaded next, depends on additional Perspectives.
Here, if object of Class Plan is selected, the perspective Plan -> Rum is used, and Rum objects are loaded (visible with numbers 101, 102...)
