Rays of light travel from the object, through the picture plane, and to the viewer's eye. This is the basis for graphical perspective. Perspective works by representing the light that passes from a scene through an imaginary rectangle (the picture plane), to the viewer's eye, as if a viewer were looking through a window and painting what is seen directly onto the windowpane.
Isometric graph paper or 3D graph paper is a triangular graph paper which uses a series of three guidelines forming a 60° grid of small triangles. The triangles are arranged in groups of six to make hexagons. The name suggests the use for isometric views or pseudo-three-dimensional views. Among other functions, they can be used in the design ...
The Penrose triangle, also known as the Penrose tribar, the impossible tribar, [1] or the impossible triangle, [2] is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing. It cannot exist as a solid object in ordinary three-dimensional Euclidean space, although its surface ...
Pieter Cornelis Mondriaan (Dutch: [ˈpitər kɔrˈneːlɪs ˈmɔndrijaːn]; 7 March 1872 – 1 February 1944), known after 1906 as Piet Mondrian (/ p iː t ˈ m ɒ n d r i ɑː n /, US also /-ˈ m ɔː n-/, Dutch: [pit ˈmɔndrijɑn]), was a Dutch painter and art theoretician who is regarded as one of the greatest artists of the 20th century.
An aperiodic tiling using a single shape and its reflection, discovered by David Smith. An aperiodic tiling is a non-periodic tiling with the additional property that it does not contain arbitrarily large periodic regions or patches. A set of tile-types (or prototiles) is aperiodic if copies of these tiles can form only non- periodic tilings.
Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
Paul Klee (German: [paʊ̯l ˈkleː]; 18 December 1879 – 29 June 1940) was a Swiss-born German artist. His highly individual style was influenced by movements in art that included expressionism, cubism, and surrealism.
In geometry, the triangular tiling or triangular tessellation is one of the three regular tilings of the Euclidean plane, and is the only such tiling where the constituent shapes are not parallelogons. Because the internal angle of the equilateral triangle is 60 degrees, six triangles at a point occupy a full 360 degrees.
