Abstract
Using various embodiments, systems, methods and techniques to determine a geometrical area of projection of a multidimensional object are described. This includes determining, by a computer system, a set of visible faces projected by a camera on a viewport space displayed on a graphical user interface, where the multidimensional object is presented in an electronically generated multidimensional environment, projecting vertices of each face in the set of visible faces that are visible on the viewport space, determining a set of polygons of each face based on the projected vertices of each respective face, and calculating an area of each polygon in the set of polygons. Thereafter, a summation of the area of each polygon in the set of polygons is performed to determine the geometrical area of projection of the multidimensional object.
