  2. Map (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Map_(higher-order_function)

    Map functions can be and often are defined in terms of a fold such as foldr, which means one can do a map-fold fusion: foldr f z . map g is equivalent to foldr (f . g) z. The implementation of map above on singly linked lists is not tail-recursive, so it may build up a lot of frames on the stack when called with a large list. Many languages ...

  7. Cube mapping - Wikipedia

    en.wikipedia.org/wiki/Cube_mapping

    The one downside to this method is that computing cube maps to properly represent a skylight is very complex; one recent process is computing the spherical harmonic basis that best represents the low frequency diffuse illumination from the cube map. However, a considerable amount of research has been done to effectively model skylight illumination.
