Continuous Cube Mapping
Cindy M. Grimm, Bill Niebruegge · Journal of Graphics Tools · 2007
Existing environment-mapping techniques include spherical mapping and cube mapping. These techniques have inherent flaws that cause sampling issues and aliasing. Continuous cube mapping is offered as an alternative environment-mapping approach that effectively folds the cube onto the sphere, providing a better parameterization of cube mapping. We provide a hardware implementation. Source code is available online.
