A machine accesses view maps that each corresponds to a different point on a surface of a three-dimensional object. The machine generates vectors of coefficients by calculating a corresponding transform of each view map. The vectors specify a corresponding coefficient for each basis function among a group of basis functions. For each basis function in the group, the machine generates a spatial representation of coefficients specified for that basis function across all of the accessed view maps, and then quantizes the spatial representation of coefficients for that basis function. The quantized spatial representation forms part of a group of quantized spatial representations of coefficients that corresponds to the accessed view maps. The machine then provides the group of quantized spatial representations of coefficients as a compressed version of the view maps. A decoder device can then approximate the view maps based on the group of quantized spatial representations.
