Two-Dimensional
(adjective)
Existing in two dimensions. Not creating the illusion of depth.
Examples of Two-Dimensional in the following topics:
-
Shape and Volume
- Shape refers to an area in a two-dimensional space that is defined by edges; volume is three-dimensional, exhibiting height, width, and depth.
- Shape refers to an area in two-dimensional space that is defined by edges.
- In two-dimensional art, the "picture plane" is the flat surface that the image is created upon, such as paper, canvas, or wood.
- Combining two or more shapes can create a three-dimensional shape.
- While three-dimensional forms, such as sculpture, have volume inherently, volume can also be simulated, or implied, in a two-dimensional work such as a painting.
-
Two-Dimensional Space
- Two-dimensional, or bi-dimensional, space is a geometric model of the planar projection of the physical universe in which we live.
- Two dimensional, or bi-dimensional, space is a geometric model of the planar projection of the physical universe in which we live.
- The two dimensions are commonly called length and width.
- In art composition, drawing is a form of visual art that makes use of any number of drawing instruments to mark a two-dimensional medium (meaning that the object does not have depth).

Distortions of Space and Foreshortening
- Distortion is used to create various representations of space in two-dimensional works of art.
- However, it is more commonly referred to in terms of perspective, where it is employed to create realistic representations of space in two-dimensional works of art.
- Perspective projection distortion is the inevitable misrepresentation of three-dimensional space when drawn or "projected" onto a two-dimensional surface.
- It is impossible to accurately depict three-dimensional reality on a two-dimensional plane.
- Giotto is one of the most notable pre-Renaissance artists to recognize distortion on two-dimensional planes.
-
Foreshortening
- Along with linear perspective, foreshortening is one of the two most characteristic features of perspective in two-dimensional media.
- Although foreshortening is an important element in art where visual perspective is being depicted, it also occurs in other types of two-dimensional representations of three-dimensional scenes.
- Following the Renaissance, foreshortening became a standard part of the training of artists and is used commonly in many two-dimensional works.
-
Assemblage
- Assemblage is the practice of creating two-dimensional or three-dimensional artistic compositions by combining and manipulating found objects.
- Assemblage is an artistic process whereby two or three dimensional artistic compositions are created by combining found objects.
-
Contour Line
- The line is an essential element of art, defined as a mark that connects the space between two points and taking any form along the way.
- Line is used most often to define shape in two-dimensional works and is the most ancient and form of mark making, as well as the most universal.
- However, because contour can convey a three-dimensional perspective, length and width as well as thickness and depth are important; not all contours exist along the outlines of a subject.
-
Emphasis
- Form may be created by the forming of two or more shapes or as three-dimensional shapes (cube, pyramid, sphere, cylinder, etc.).
- It may be enhanced by tone, texture and color and is considered three-dimensional showing height, width and depth.
- There are two types of space: positive and negative space.
- Shape pertains to the use of areas in two dimensional space that can be defined by edges, setting one flat specific space apart from another.
- As an art element, line pertains to the use of various marks, outlines and implied lines in artwork and design, most often used to define shape in two-dimensional work.
-
Implied Line
- The line is an essential element of art, and is defined as a mark that connects the space between two points, taking any form along the way.
- Line is used most often to define shape in two-dimensional works and is the most ancient and form of mark making, as well as the most universal.
- They are created by visually connecting two or more areas together.
- Implied lines can also be created when two areas of different colors or tones come together.
- Implied lines are found in three-dimensional artworks as well.
-
Other Forms of Cubism
- Initially the Constructivists worked on three-dimensional constructions as a means of participating in industry.
- Later the definition would be extended to designs for two-dimensional works such as books and posters.
-
Modeling
- Two processes are responsible for all three-dimensional art: (1) the additive process, in which material is built up to create form, and (2) the subtractive process, where form is created by removing material from an existing mass, such as a chunk of stone, wood or clay.
- Additive and subtractive processes are not mutually exclusive; it is not uncommon for three-dimensional art to make use of both processes.
