There are several terms used to describe the technique of making a 2D painting or drawing appear 3D. One such term is anamorphic painting, which is a form of optical illusion that creates the impression of three-dimensional space and objects on a two-dimensional surface. This technique has been used since the Middle Ages and is often employed in murals and street art. Another term is trompe-l'œil, which is French for deceive the eye, and refers to the highly realistic optical illusion of creating three-dimensional objects on a flat surface. Artists may also refer to the process of creating 3D images in art as rendering, modelling, or sculpting.

What You'll Learn

Rendering
3D paintings are also known as anamorphic paintings, which are designed and drawn in an anamorphic way on a 2D surface. These paintings are usually meaningless and ugly at first glance, but when viewed from the right angle, they reveal a 3D image. This technique is a type of optical illusion, also known as trompe-l'œil, which means "deceive the eye" in French.
In both traditional and digital rendering, the use of light and shadow is crucial to achieving the desired three-dimensional effect. Hard, soft, fuzzy, and lost edges are employed to create the illusion of depth, with core and cast shadows enhancing the sense of dimension. This technique is often referred to as "sculpting," as it involves bringing a 3D image out of a flat surface, much like a sculptor brings form to a block of stone.

Modelling
The term "modelling" is often used interchangeably with other words such as "form", "depth", "shading", and "rendering". While shading is a key technique used in modelling, some artists differentiate between the two, suggesting that shading is a technique used within the process of modelling. Rendering, on the other hand, is sometimes used as a more specific term for the final stage of the process, where shading techniques are applied to complete the three-dimensional effect.
Leonardo da Vinci, for example, was known to work from highlights to shadows, training his eyes and hands to recreate what he saw by understanding the relationships between light and dark. He described this process as "without lines or borders, in the manner of smoke or beyond the focus plane", and this technique is evident in his famous painting, the Mona Lisa.
In modern times, modelling has evolved to include digital design methods, where artists use computer graphics and printing capabilities to create 3D effects. This can involve the use of optical illusion techniques such as anamorphosis, a term that has been used since the Middle Ages to describe the process of turning 2D images into three-dimensional impressions. Iranian artist Saleh Sokhandan, for instance, combines digitally transformed paintings with volumes to create 3D effects.

Anamorphic painting
The term "anamorphic painting" refers to a style of art that creates a three-dimensional illusion when viewed from a specific vantage point or with the aid of a tool such as a curved mirror. This technique, also known as anamorphosis, dates back to the 17th century, with the term derived from the Greek word for transformation. Anamorphic paintings are designed and drawn on a two-dimensional surface in a distorted manner, only revealing their true 3D form when viewed from the correct angle.
Anamorphic art has been used in various fields, including painting, sculpture, photography, and installation art. One of the earliest written descriptions of anamorphic technique can be found in "The Two Rules of Practical Perspective," compiled between 1530 and 1540 by Giacomo Barozzi da Vignola. However, it is believed that artists Leonardo da Vinci and Albrecht Durer created some of the first anamorphic designs, with da Vinci's notebooks featuring several distorted faces that appear in the correct perspective when viewed from a precise angle.
The appeal of anamorphic art lies in its ability to conceal images and messages within a painting, only revealing them to viewers who approach the artwork from a specific vantage point. This technique was used by artists such as Hans Holbein the Younger, who included subtle, abstract messages in his paintings, such as "The Ambassadors," which features a human skull in the foreground that can only be seen from the bottom right-hand corner.
Creating anamorphic paintings requires a careful understanding of light and shadow, edges, and shadows to achieve the illusion of depth and dimension. Artists may also employ vinyl or laser-and-rendering techniques to achieve the desired effect, especially in installations where painting on walls is not permitted.

Trompe-l'œil
In the 15th century, Italian artists like Andrea Mantegna and Melozzo da Forlì employed trompe-l'œil techniques in their ceiling paintings, creating the impression of greater space. This style of painting continued to be popular in the 16th and 17th centuries, with Flemish and Dutch painters such as Cornelis Norbertus Gysbrechts creating chantourné paintings, which are trompe-l'œil representations designed to stand away from a wall.

Frescography
The term "3D painting" is often used to refer to anamorphic paintings, which are paintings that create the illusion of three dimensions when viewed from a specific angle. Another term for this style of art is trompe-l'œil (French for "deceive the eye"), which involves tricking the viewer into perceiving painted objects or spaces as real.
One specific type of 3D painting is frescography, invented in 1998 by German muralist Professor Rainer Maria Latzke. Frescography is a method for producing murals digitally on various surfaces, such as paper, canvas, glass, or tiles. It involves using computer-aided manufacturing (CAM) and digital printing methods to create seamless, tailor-fit wall murals.
Frescographies are commonly printed on wide-format printers and can be found in various locations, such as the Lanner Lehar Hall of the Vienna Town Hall and the world's largest cruising ship, the Royal Clipper. The technique is also used by the Institute of Frescography (IOF), founded by Professor Latzke, to improve public knowledge and interest in mural and fresco painting, as well as for research and educational purposes.
