Ditch (fortification)
A ditch in military engineering is an obstacle, designed to slow down or break up an attacking force, while a trench is intended to provide cover to the defenders. In military fortifications the side of a ditch (or gorge) farthest from the enemy and closest to the next line of defence is known as the scarp while the side of a ditch closest to the enemy is known as the counterscarp.
Uses
In early fortifications, ditches were often used in combination with ramparts to slow down the enemy whilst defensive fire could be brought to bear from the relative protection afforded by the rampart and possibly the palisade. In medieval fortification, a ditch was often constructed in front of a defensive wall to hinder mining and escalade activities from an attacker. When filled with water, such a defensive ditch is called a moat. However, moats may also be dry.
Later star forts designed by military engineers like Vauban, comprised elaborate networks of ditches and parapets, carefully calculated so that the soil for the raised earthworks was provided, as nearly as possible, entirely by the excavations whilst also maximising defensive firepower.

Indigo Renderer
Indigo Renderer is a 3D rendering software that uses unbiased rendering technologies to create photo-realistic images. In doing so, Indigo uses equations that simulate the behaviour of light, with no approximations or guesses taken. By accurately simulating all the interactions of light, Indigo is capable of producing effects such as:
Indigo uses methods such as Metropolis light transport (MLT), spectral light calculus, and virtual camera model. Scene data is stored in XML or IGS format.

Indigo (Warner novel)
Indigo is a novel written by Marina Warner, published by Simon & Schuster in 1992 (ISBN 0-671-70156-8). It is a modernized and altered retelling of William Shakespeare's, The Tempest. Within the novel, Warner appropriates Shakespeare's original plot and characters to fit a dual reality, spanning the 17th and 20th Centuries, and the colonial sphere of the Caribbean alongside post-colonial London. She expands certain characters, for example, Sycorax, Shakespeare's dark witch, is given her own identity as indigo maker and village sage. The colonialist realities of 'discovery' and the conquering of 'new' lands are played out in the novel's first section. Finally, the characters of Miranda and Caliban (recreated as Dulé and George/Shaka) are unified in a shared acknowledgement of past colonial wrongs.
