1. A method to determine whether a surface of the multidimensional object is projected on a camera on a viewport space displayed on a graphical user interface, comprising:
projecting a first vector normal to a surface of the multidimensional object, wherein the multidimensional object is rendered in an electronically generated multidimensional environment;
projecting a second vector from the camera to the surface of the multidimensional object;
determining an angle between the first vector and the second vector; and
based on the angle determining whether the surface is projected on the viewport space.
