1. A method of communicating a three-dimensional scene to a rendering device, the method comprising: providing a computational description of the three-dimensional scene to be rendered, the three-dimensional scene comprising visual elements; utilizing a skeletal tracker to detect skeletal parts of a body within the three-dimensional scene; using a computing device, performing an automated evaluation of the three-dimensional scene to identify predetermined visual elements having an elevated perceptual importance to the three-dimensional scene; assigning an importance weight to the visual elements of the three-dimensional scene, the respective importance weight of each visual element being related to the perceptual importance of the corresponding visual element among other visual elements, and using the detected skeletal parts of the body, assigning importance weight to respective detected skeletal parts of the body relative to other detected skeletal parts of the body within the three-dimensional scene; and preparing the computational description for transmission to the rendering device, including reducing a level of detail in the computational description to conform with one or more resource constraints related to the rendering device, the level of detail being reduced non-uniformly with respect to the visual elements of the three-dimensional scene, in which visual elements, including the skeletal parts of the body, having a corresponding higher importance weight are preserved at a higher level of detail.
