Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his 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.
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.
The Lego Mindstorms programmable construction set system is named after the book. [2] In 2017, thanks to Papert's family, the book was made freely available online here. Papert describes the Turtle as an "object-to-think-with" and discusses many code examples of Turtle Graphics.
Logo's most-known feature is the turtle (derived originally from a robot of the same name), [5] an on-screen "cursor" that shows output from commands for movement and small retractable pen, together producing line graphics. It has traditionally been displayed either as a triangle or a turtle icon (though it can be represented by any icon).
For example, with 6 lines of code, it is possible to demonstrate a random network image viewer using Flickr as the source. [1] The system utilizes the Microsoft Visual Studio IDE to provide auto-completion and context-sensitive help. Basic-256 is an easy-to-use version of BASIC designed to teach anybody the basics of computer programming.
Small Basic includes a "Turtle" graphics library that borrows from the Logo family of programming languages. For example, to draw a square using the turtle, the turtle is moved forward by a given number of pixels and rotated 90 degrees in a given direction. This action is then repeated four times to draw the four sides of the square.
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.
Turtle syntax is similar to that of SPARQL, an RDF query language. It is a common data format for storing RDF data, along with N-Triples , JSON-LD and RDF/XML . RDF represents information using semantic triples , which comprise a subject, predicate, and object.
