1. A method for representing a three-dimensional scene using fixed point data, the method comprising the steps of: determining a quantization transform corresponding to a geometric object, the geometric object representing at least a portion of the three-dimensional scene, the quantization transform useable for converting a floating point space to a fixed point space, wherein the floating point space contains one or more floating point data corresponding to the geometric object; and converting, by using the quantization transform, the one or more floating point data to one or more fixed point data.
