1. A computer-implemented method comprising: selecting a height map intersection point using a first processor; identifying a first data point and a second data point that are adjacent to the height map intersection point; retrieving normalized data corresponding to the first data point and the second data point; including the normalized data in a data stream; and sending the data stream to a second processor, wherein the second processor is adapted to generate one or more image values corresponding to the height map intersection point using the normalized data.
