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.
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black).
Blend modes. A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes[ 1] or mixing modes[ 2]) in digital image editing and computer graphics are used to determine how two layers are blended with each other.
In the Wild Kratts team's turtle-shaped aircraft and headquarters—the Tortuga, one of Aviva's greatest inventions—the Wild Kratts tech team, consisting of Aviva, communications expert and mechanic Koki (Heather Bambrick), and skilled pilot Jimmy Z (Jonathan Malen) monitor Chris and Martin and watch as the mother crocodile faithfully guards ...
Reticulated python. The reticulated python ( Malayopython reticulatus) is a python species native to South and Southeast Asia. It is the world's longest snake, and the third heaviest after the green anaconda and Burmese python. It is listed as least concern on the IUCN Red List because of its wide distribution.
The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. [ a] It expresses color as three values: L* for perceptual lightness and a* and b* for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually ...
Turtle (syntax) In computing, Terse RDF Triple Language ( Turtle) is a syntax and file format for expressing data in the Resource Description Framework (RDF) data model. 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 .
Logo is an educational programming language, designed in 1967 by Wally Feurzeig, Seymour Papert, and Cynthia Solomon. [ 1] Logo is not an acronym: the name was coined by Feurzeig while he was at Bolt, Beranek and Newman, [ 2] and derives from the Greek logos, meaning 'word' or 'thought'. A general-purpose language, Logo is widely known for its ...
