1. A method comprising, by a computer system comprising one or more computing devices:
obtaining one or more source images including at least one 3-dimensional scan of a human body surface;
automatically identifying, based on the at least one 3-dimensional scan, a feature of the human body surface;
generating a digital 3-dimensional model of the human body surface, wherein the digital 3-dimensional model includes the identified feature of the human body surface and surface geometry of a sub-feature of the identified feature;
generating a reverse-feature digital model of the digital 3-dimensional model of the human body surface, wherein the reverse-feature digital model includes a surface that is the reverse of the surface geometry of the sub-feature in the digital 3-dimensional model; and
transmitting at least one of the digital 3-dimensional model or the reverse-feature digital 3-dimensional model to a manufacturing computer system for use in a manufacturing process, wherein output of the manufacturing process is based at least in part on the digital 3-dimensional model.
