Systems, methods and apparatus for generating an asset for a simulated environment using digital image capture are disclosed. An outline of an object in a digital image is automatically traced to generate data representing a two-dimensional polygon that encompasses the object. The outline is traced without relying on further input from a user once the digital image of the object has been captured. A portion of the digital image bounded by the two-dimensional polygon is separated from a remaining portion of the digital image. The portion of the image bounded by the two-dimensional polygon is associated with an asset in the simulated environment.
