A figure explaining point-projection prospective. S is the distance between an observer's eye and an observation point on an object that is a long rectangular wall facing to the observer at a tilted angle. If the observation distance becomes N times longer, then the apparent height of the wall at the observation point is roughly N times smaller.
The vanishing point may also be referred to as the "direction point", as lines having the same directional vector, say D, will have the same vanishing point. Mathematically, let q ≡ ( x , y , f ) be a point lying on the image plane, where f is the focal length (of the camera associated with the image), and let v q ≡ ( x / h , y ...
A figure is a representation including both shape and size (as in, e.g., figure of the Earth). A plane shape or plane figure is constrained to lie on a plane, in contrast to solid 3D shapes. A two-dimensional shape or two-dimensional figure (also: 2D shape or 2D figure) may lie on a more general curved surface (a two-dimensional space).
Pivot Animator (formerly Pivot Stickfigure Animator and usually shortened to Pivot) is a freeware application that allows users to create stick-figure and sprite animations, and save them in the animated GIF format for use on web pages and the AVI format (in Pivot Animator 3 and later).

The interior angle concept can be extended in a consistent way to crossed polygons such as star polygons by using the concept of directed angles.In general, the interior angle sum in degrees of any closed polygon, including crossed (self-intersecting) ones, is then given by 180(n–2k)°, where n is the number of vertices, and the strictly positive integer k is the number of total (360 ...
