Vanishing pointA vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of parallel lines in three-dimensional space appear to converge. When the set of parallel lines is perpendicular to a picture plane, the construction is known as one-point perspective, and their vanishing point corresponds to the oculus, or "eye point", from which the image should be viewed for correct perspective geometry.
Picture planeIn 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. It is usually coextensive to the material surface of the artwork. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.Parallel projectionIn three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other. It is a basic tool in descriptive geometry. The projection is called orthographic if the rays are perpendicular (orthogonal) to the image plane, and oblique or skew if they are not.
Descriptive geometryDescriptive geometry is a type of technical drawing and the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. The resulting techniques are important for engineering, architecture, design and in art. The theoretical basis for descriptive geometry is provided by planar geometric projections.
Perspective (graphical)Perspective (from Latin'to see through') is the representation of objects on the basis of how they may appear in real-life. Perspective is an approximate representation, generally on a flat surface, of an object as it is seen by the eye. Perspective is useful for representing a three-dimensional scene in a two-dimensional medium, like paper.*As an Amazon Associate I earn from qualifying purchases.
