  • Patent number: 11188739
    Abstract: An example method includes: obtaining, from computer memory, information from a three-dimensional (3D) graphical model that represents an object; identifying, based on the information, a first part of the object having an attribute; performing a recognition process on the object based on features of the object, where the recognition process attaches more importance to a second part of the object than to the first part, with the second part either not having the attribute or having less of the attribute than the first part; and providing data for rendering content on a graphical user interface based, at least in part, on recognition of the object performed by the recognition process.
