In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.
Reverse perspective, also called inverse perspective, [1] inverted perspective, [2] divergent perspective, [3] [4] or Byzantine perspective, [5] is a form of perspective drawing where the objects depicted in a scene are placed between the projective point and the viewing plane.
The central visual element, known as element of design, formal element, or element of art, constitute the vocabulary with which the visual artist compose. These elements in the overall design usually relate to each other and to the whole art work. The elements of design are: Line — the visual path that enables the eye to move within the piece
If a geometric shape can be used as a prototile to create a tessellation, the shape is said to tessellate or to tile the plane. The Conway criterion is a sufficient, but not necessary, set of rules for deciding whether a given shape tiles the plane periodically without reflections: some tiles fail the criterion, but still tile the plane.

Comparison of several types of graphical projection, including elevation and plan views. To render each such picture, a ray of sight (also called a projection line, projection ray or line of sight) towards the object is chosen, which determines on the object various points of interest (for instance, the points that are visible when looking at the object along the ray of sight); those points of ...
In elementary geometry, a face is a polygon [2] on the boundary of a polyhedron. [1] [3] (Here a "polygon" should be viewed as including the 2-dimensional region inside it.) Other names for a polygonal face include polyhedron side and Euclidean plane tile. For example, any of the six squares that bound a cube is a face of the cube.
The Four Philosophers (c. 1615.Oil on panel; 167 x 143 cm, Pitti Palace, Florence).In his friendship portrait of himself, his brother Philip Rubens, Justus Lipsius and Jan van den Wouwer (left to right), the painter Rubens's self-portrait on the left is an example of a figural repoussoir that is further accentuated by the flowing red curtain.
