Sketch is a simple system for producing line drawings of three-dimensional objects and scenes. Sketch is intended to produce finely wrought, mathematically-based illustrations with no extraneous detail and be able to easily overlay TeX math and text. The input language is reminiscent of PSTricks, so will be easy to learn for current PSTricks users. It generates either PSTricks or TikZ/PGF code as output. . Note that this package is not the interactive vector drawing program now known as skencil.
