An animation that shows how the turtle is used to create graphics by combining forward and turn commands while a pen is touching the paper A spiral drawn with an iterative turtle graphics algorithm A turtle graphic pattern drawn with a Python program. The turtle has three attributes: a location, an orientation (or direction), and a pen. The pen ...
LibreLogo is an integrated development environment (IDE) for computer programming in the programming language Python, which works like the language Logo using interactive vector turtle graphics. Its final output is a vector graphics rendition within the LibreOffice suite. It can be used for education and desktop publishing.
Turtle graphics were added to the Logo language by Seymour Papert in the late 1960s to support Papert's version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.
The first part of learning Logo deals with "turtle graphics" (derived from turtle robots) used as early as 1969. In modern implementations, an abstract drawing device, called the turtle, is used to make programming for children very attractive by concentrating on doing turtle graphics.
Seymour Aubrey Papert (/ ˈ p æ p ər t /; 29 February 1928 – 31 July 2016) was a South African-born American mathematician, computer scientist, and educator, who spent most of his career teaching and researching at MIT.
Delta Drawing Learning Program, later retitled Delta Drawing Today, is a turtle graphics drawing program developed by Computer Access Corporation, [1] and published by Spinnaker Software in 1983. Delta Drawing was intended for children age 4 to 14. It features a functional programming language for executing scripted drawing and painting ...
This is a "genealogy" of programming languages.Languages are categorized under the ancestor language with the strongest influence. Those ancestor languages are listed in alphabetic order.
N3 or Notation3, a non-standard serialization that is very similar to Turtle, but has some additional features, such as the ability to define inference rules. RDF/XML, [32] an XML-based syntax that was the first standard format for serializing RDF. RDF/JSON, [33] an alternative syntax for expressing RDF triples using a simple JSON notation.
