Claim of US Patent No. 9,881,418

1. A method comprising:
receiving a computer representation of an object;
identifying, by a processing device, a protruding feature of the computer representation of the object bound by a non-concave
edge or a receding feature of the computer representation of the object bound by a non-convex edge, wherein a non-concave
edge is incident to a first face and to a second face such that respective normal vectors of the first face and the second
face point away from each other or are parallel, and wherein a non-convex edge is incident to a third face and a first face
such that respective normal vectors of the third face and the fourth face point towards each other or are parallel;

generating a simplified computer representation of the object by removing at least one of: the identified protruding feature
or receding feature; and

storing the simplified computer representation for rendering the simplified computer representation of the object on a display.
