Discover the Many Worlds of Perspective

The Perspective Research Centre (PRC) explores visual, optical and technical perspective across art, science and technology.

Perspective is far more than a drawing method. It shapes how we view, match and represent spatial reality—and how we create visual illusion and immersive experience—across art, architecture, geometry, photography, cinema, scientific imaging, computer graphics, virtual reality, AI and robotics.

Whether you seek a new solution, clarity on a difficult visual problem or a deeper understanding of perspective, you have come to the right place.

A subject in need of clarification

Perspective is a vast, rapidly developing and often misunderstood subject. New technological forms of perspective are emerging at an unprecedented rate, while fundamental theoretical questions remain unresolved and substantial areas require further research.

Despite the thousands of books, treatises and articles devoted to it, perspective remains only partially documented and theoretically challenging, even among teachers and specialists. Its many types, forms and phenomena—and the inconsistent ways in which they have been classified and described—can obscure the processes underlying visual effects.

Because perspective has never been established as a distinct discipline, many of its axioms, basic principles and central facts remain scattered, obscured or insufficiently documented. Others have never been fully worked out or traced through their wider implications. Its terminology is equally inconsistent, often giving one concept several names—or one name to different, even opposing, ideas.

The PRC framework is designed to organise and simplify this complex field, resolve common errors and misconceptions, and represent its natural, visual, optical, geometrical and technical processes accurately.

The PRC in numbers

Over four decades, the Perspective Research Centre has produced more than three million words on perspective. Most recently, five years were devoted to creating the 350,000-word Dictionary of Perspective—a comprehensive synthesis of the field.

Perspective contains many mysteries, unresolved questions and surprising facts. The scale, scope and depth of the PRC’s work bring together an extraordinary body of visual knowledge—designed to answer questions, clarify difficult problems and reveal aspects of perspective that are rarely explained elsewhere.

The PRC’s research, publications and collections include approximately:

250+ specialist web pages · 1,200 types and forms of perspective
5,000 library volumes · 15,000 bibliographic titles · 4,000+ dictionary terms

The scale and diversity of perspective

Perspective encompasses an extraordinary range of natural, visual, optical, geometrical and technical systems. The Dictionary of Perspective identifies approximately 1,200 types and forms across art, science, technology, vision, imaging and spatial representation.

What is perspective?

Perspective concerns the relationships between space, vision, representation and measurement.

It encompasses the natural conditions of seeing; the optical behaviour of light, eyes and instruments; and the artificial systems used to record, construct and represent space in drawings, photographs, films, screens, simulations and digital environments.

Linear perspective is only one part of this much larger field.

Our mission

The Perspective Research Centre collects, organises, classifies and develops knowledge of perspective across the arts, sciences and technologies. It brings together historical and contemporary theories, methods, instruments, applications and visual systems from Western and non-Western traditions.

Our long-term aim is to help establish perspective science as a unified interdisciplinary field concerned with how spatial reality is seen, imaged, represented, transformed, measured and understood. To support this aim, we are developing Perspective Category Theory: a coherent framework for organising the many types, forms, processes and applications of perspective.

Perspective across disciplines

Across the arts, sciences and technologies, perspective serves five principal goals: to view, match and represent spatial reality, and to create visual illusion and immersive experience.

New perspectives, practical solutions

The Dictionary of Perspective explains more than 4,000 terms and documents more than 200 new or refined concepts, distinctions and classifications, including overlooked principles, methods and phenomena across visual practice. It helps newcomers and specialists extend their knowledge, solve visual problems and strengthen professional practice.

Examples include:

• Defining the basic operating principles of Linear Perspective — fixed viewpoint, visual projection onto a picture plane, the Size–Distance Law, straightness, picture-plane parallelism, and the systematic organisation of parallel lines and planes through vanishing structures.
• Applying the Equivalence or Correspondence Problem to drawing, photography, reconstruction, computer vision and AI.
• Using Blended Scene, Cylindrical, Curvilinear or Spherical Perspective to create unconventional, panoramic or immersive spaces.
• Distinguishing apparent Vanishing Points, Lines and Planes from Original Lines and Original Planes to clarify the underlying structure of perspective views and images.
• Distinguishing Directional Line Vanishing from Aspect Vanishing: parallel lines converge towards vanishing structures, while visible plane surface progressively diminishes as viewing aspect approaches edge-on; when a plane’s imaginary extension passes through the eye-point, it coincides with the corresponding Visual Plane and is seen edge-on as a line.
• Understanding the visual alignment effects of the Visual Element of the System: lines parallel to the sight-line direction converge to the point of sight; planes aligned with the visual plane appear edge-on as a line; other planes of the same parallel family undergo aspect vanishing towards this limiting line.
• Distinguishing Optical Vanishing from Geometrical Vanishing to separate visual disappearance or loss of visibility from geometrical convergence towards vanishing structures.
• Applying the Shape Sufficiency Problem to ask whether real structures sufficiently approximate the required geometric Forms at a given scale for perspective geometry to remain valid.
• Applying the Scale–Shape–Size Problem to show why relationships observed at one scale cannot automatically be treated as universally valid.
• Distinguishing the Sphere of Revolution from the Sphere of Vision in art, CGI, VR and panoramic imaging, clarifying looking-at, looking-through and looking-around views.
• Using Category Chaining to trace visual transformations through scene, capture, processing, display and perception.

These examples alone demonstrate how complex perspective can be. The wider field contains many other fundamental facts and processes that can be similarly difficult to grasp. Yet once a relatively small number of basic axioms and principles are understood, the pieces begin to fall into place: the wider landscape of perspective becomes comprehensible, and its many possibilities become both clear and exciting.

Library, bibliography and archives 

The Library of Perspective contains approximately 5,000 physical volumes, thousands of digital publications and an extensive image archive. Download the Library of Perspective Catalogue (PDF, 66 MB)

The PRC also provides open access to the multi-volume  Encyclopedia of Perspective and the Bibliography of Perspective, which comprises around 15,000 titles and has been developed over more than 70 years from the work of Luigi Vagnetti and Kim Veltman. The Centre also preserves Professor Kim Veltman’s archive of 400 publications on perspective, visual knowledge, Leonardo da Vinci, media theory and the history of science.

The site also provides numerous specialist resources on perspective, including a historical timeline and comprehensive study, teaching and learning guides.

FORTHCOMING FIRST EDITION

Natural and Visual Perspective

A new account of how spatial reality gives rise to natural appearance—and how natural appearance becomes human visual experience.

Natural and Visual Perspective provides a detailed examination of Natural Perspective and Visual Perspective Type 2: the optical, geometrical, retinal and perceptual processes through which spatial reality is seen and experienced.

Through original theoretical diagrams and Perspective Category Theory, the book examines monocular and binocular vision, retinal image formation, stereopsis, natural scaling, visual distortion, the Sphere of Vision, and optical and geometrical vanishing structures.
