G06T 15/00

US Classification:

345520, 345419, 345582

Abstract:

Techniques for selectively displaying surfaces of an object model to a user are described. In one embodiment, a computer-implemented method may include, for a given one of a plurality of surfaces included in an object model that is representative of a physical object, determining a normal vector of the given surface. The method may also include determining an angle between the normal vector of the given surface and a current viewing direction of the model. The method may further include displaying the object model to a user without displaying the given surface to the user, dependent upon determining that the angle between the normal vector and the current viewing direction is greater than a threshold value.
