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. |
