cube map
A texture made of six square images arranged as the faces of a cube, sampled by pointing a direction outward from the center.
Instead of looking up a color by 2D coordinates, a cube map is sampled with a 3D direction vector, and the hardware picks the right face and spot automatically. This is the standard trick for environment reflections and skyboxes, where you want a full surround image. microZeus supports sampling them from just-in-time compiled shaders.
