Transmission and configuration of three dimensional digital content is described. In one or more implementations, three-dimensional digital content is received having a three-dimensional mesh of a plurality of vertices. Each vertex includes a definition of a characteristic of the three-dimensional content. The definition of the characteristic is transformed for each vertex from a floating point representation to a fixed point representation. The fixed point representation includes a plurality of values that have different amounts of significance in defining the characteristic, one to another. The plurality of values is indexed of the fixed point representation of the definition of the characteristic. The indexing is based on the different amounts of significance, one to another. Output of the three dimensional digital content is controlled based on the indexed plurality of values.
