1. A method for managing a consumer representation, comprising: detecting, by at least one computer system, a rendering constraint for a maximum time between capture of each a plurality of frames of a captured video stream of a consumer and a rendering of each corresponding frame of a consumer representation comprising a rendered three dimensional model rendered to depict a consumer appearance and a movement in each of the plurality of frames wearing a particular merchandise item not captured in the captured video stream from among a plurality of merchandise items; selecting, by the at least one computer system, a particular selection of processor elements accessible to the at least one computing system that are able to generate the rendered three dimensional model within the time period specified in the rendering constraint from among a plurality of processor elements accessible to the at least one computer system; directing, by the at least one computer system, at least one processing task from among a plurality of processing tasks to the selected particular selection of processor elements to build the consumer representation comprising the three dimensional model and generate a rendering of the three dimensional model wearing the particular merchandise item as the captured video stream is received in real time at the at least one computer system; and delivering, by the at least one computer system, each rendered frame of the three dimensional model to a display interface within the time period specified in the rendering constraint, such that the display of the rendering appears to the consumer as if the consumer is looking into a mirror when viewing the rendering at the display interface.
