One or more embodiments of the present disclosure provide an apparatus used in source data compression, comprising a memory and a at least one processor. The memory is configured to store vertex attribute data and a set of instructions. The processor is coupled to the memory. The processor is configured to receive a source data stream that includes one or more values corresponding to the vertex attribute data. The processor is also configured to provide a dictionary for the one or more values in the source data stream, wherein the dictionary includes a plurality of index values corresponding to the one or more values in the source data stream. The processor is also configured to lace at least some of the one or more values in the source data stream with corresponding index values of the plurality of index values.
