Noun
hemicube (plural hemicubes)
(geometry) An abstract regular polyhedron containing half the faces of a cube.
The projection onto the hemicube, which could be adapted from standard methods for determining the visibility of polygons, also solved the problem of intervening patches partially obscuring those behind. Source: Internet
The surface of the hemicube was divided into pixel-like squares, for each of which a view factor can be readily calculated analytically. Source: Internet
