Unicube
Unicube or Unicube mapping is an approach for environment mapping. Analogous to cube mapping, it exploits the six-face structure but samples the spherical surface more evenly. It has the advantages that can fit to the hardware support of cube mapping and preservation of rectilinear structure. The implementation is simple which uses a simple function to modify the look-up direction prior to the traditional cube map look-up process.

It also inherits the advantages of cube mapping. It fully exploits the cube map hardware for real-time filtering and look-up. Moreover, its rectilinear partition structure allows a direct and real-time acquisition of the environment. This feature is suitable for dynamic environment mapping application.
