Double Cross Cylinder (DCC) is an object created by intersecting the cylinder of Y-axis and the cylinder of the Z-axis. DCC mapping is a new method for effectively mapping the environment. This method eliminates the singularity effect caused in the environment maps and shows an almost even amount of area for the environment occupied by a single texel. The surrounding environment can also be stored more effectively through more accurate sampling. Improvement is also achieved in the rendering time of the DCC mapping method and octahedral mapping method based on DCC mapping. Therefore, the DCC mapping method is suitable to be applied on environment navigation systems due to its effective storage of the environment and faster sampling time.
