Hemicube




A Hemicube is a concept used in 3D Computer Graphics Rendering . A hemicube is one way to represent a 180° view from a surface or point in space.


SHAPE

Although the name implies any half of a cube, a hemicube is usually a cube cut through a plane parallel to one of its faces. Therefore it consists of one square face, and four 2:1 aspect ratio rectangles.


USES

The hemicube may be used in the Radiosity algorithm or other Light Transport Algorithms in order to determine the amount of light arriving at a particular point on a surface.

In some cases, a hemicube may be used in Environment Mapping or Reflection Mapping.
