context_page_description: In computer graphics, turtle graphics are vector graphics using a relative cursor upon a Cartesian plane. Turtle graphics is a key feature of the Logo programming language.
context_section_description: The ideas behind turtle graphics can be extended to include three-dimensional space. This is achieved by using one of several different coordinate models. If the turtle operates in cylindrical coordinates, then it has a location and a heading within its plane, and its plane may be rotated around the vertical axis. This often manifests itself as the turtle having two different heading angles, one within the plane and the other determining the plane's angle. Usually changing the plane's angle does not move the turtle.
  Other coordinate models may also be used.  Cheloniidae Turtle Graphics is a 3D turtle library for Java.
