Three-dimensional art, or 3D art, refers to any art form that is created in three dimensions, as opposed to two-dimensional art like a drawing. 3D art can be made in various ways, including sculptures, paintings, and photographs. Artists use different techniques to create the illusion of three-dimensional objects, such as shadow casting, cast shadow, and trompe l'oeil (fool the eye). These methods manipulate light and shadow to give the appearance of depth and volume. Some terms used to describe this process include rendering, modelling, form, depth, and sculpting. 3D artists may also use digital software and 3D printing to bring their ideas to life, creating intricate and impressive pieces.

Rendering
Three-dimensional art, or 3D art, refers to any art that is created in three dimensions, including sculptures, paintings, and photographs. 3D art can be used to create intricate pieces that impress and amaze viewers. This type of art is defined by its dimensions of height, width, and depth, occupying greater physical space than 2D art and allowing for interpretation from multiple sides and angles.
In the context of 3D art, rendering specifically refers to the creation of two-dimensional artwork using computers. Artists describe the scene in a way the computer can understand, and the computer simulates a 3D reality from which it takes a virtual snapshot. This snapshot can be left in a digital format or printed out. The process often begins with creating a virtual model, similar to sculpting with clay, using programs like Sculptris. More complex models may require rigging, which allows artists to reposition parts of the model without remoulding it entirely.

Modelling
Three-dimensional art, or 3D art, refers to any art that is created in three dimensions, as opposed to two-dimensional art such as a drawing. 3D art can be made in many different ways, including sculptures, paintings, and photographs. It is defined as art with all the dimensions of height, width, and depth, and it occupies greater physical space than 2D art, allowing it to be viewed and interpreted from all sides and angles.
When it comes to the specific technique of making a 2D drawing or painting appear three-dimensional, it is often referred to as "modelling" or "modeling" (with two 'l's in British English). This term is commonly used in fine art contexts. Other terms for this technique include "rendering", "sculpting", "form", "depth", and "shading". These terms refer to the process of creating the illusion of three dimensions through the manipulation of light and dark values, edges, shadows, and perspective.
One example of a modelling technique is shadow casting, where a light source projects an image onto a flat surface, and the resulting shadows are used to create a 3D effect. Another method is "cast shadow", where a flat surface is used as a background, and the cast shadows are employed to generate a sense of depth. Artists may also utilise shading techniques, where the gradual transition from light to dark values helps to suggest form and depth in a drawing.
In the digital realm, 3D artists use software to create three-dimensional virtual reality pieces. They may then use a 3D printer to print their digital artwork or mould it using materials such as plastic or metal. Some artists also collaborate with specialists known as "finishers" who assist in the painting or finishing process.
While the term "modelling" specifically refers to the act of creating the illusion of depth in a 2D work, it is worth noting that the broader term "3D art" can also encompass sculptural paintings or painterly sculptures, where the artwork itself exists in three dimensions.

Sculpting
Three-dimensional art, or 3D art, refers to any art that is created in three dimensions (height, width, and depth) rather than two. This type of art can be made in many different ways, including sculptures, paintings, and even photographs. 3D art can be used to create intricate pieces that impress viewers and can be viewed and interpreted from all sides and angles.
Free-standing sculptures are independent art objects that usually represent people, animals, or abstract themes. Relief sculptures, on the other hand, are made as elements of a larger piece of art. There are different types of relief sculptures, including bas-reliefs, high reliefs, and sunk-reliefs, which differ in how the statues stand out or are carved into the background.
In addition to traditional sculpting techniques, artists may use advanced technologies like 3D printing or modelling software to create 3D sculptures. These digital tools allow artists to design complex shapes and bring their ideas to life in a three-dimensional virtual reality before printing or moulding the final product using various materials.
When it comes to creating the illusion of three dimensions in a two-dimensional setting, such as a painting, several techniques can be employed. These include shading, modelling, rendering, and the use of light and shadow to create depth and form. Leonardo da Vinci, for example, employed this technique in his painting of the Mona Lisa, describing it as “without lines or borders, in the manner of smoke or beyond the focus plane.”

Shadow casting
Three-dimensional art, or 3D art, refers to any art that is created in three dimensions (height, width, and depth), as opposed to two dimensions like a drawing. 3D art can be made in various ways, including sculptures, paintings, and photographs.
One technique used in 3D art is shadow casting, which involves creating shadows that give the illusion of depth and make the artwork seem more realistic. Cast shadows occur when an object blocks the light source, and they can be used to indicate the shape of an object and the direction of the light source. The use of shadows in art dates back thousands of years, with examples found in ancient cave paintings and Roman mosaics.
To create cast shadows in a drawing or painting, artists use techniques such as shading, rendering, modelling, or sculpting. They manipulate light and dark areas to create the illusion of depth and make objects appear three-dimensional. One method is to define the horizon line and the light source, which is used to determine the "shadow vanishing point". Lines are drawn from the light source and the shadow vanishing point to create the cast shadow.
In addition to traditional art forms, 3D art can also be created digitally using 3D software and printed using 3D printers. Artists can use different materials and manipulate them into objects, characters, and scenes to produce intricate and impressive 3D artworks.

Three-dimensional painting
There are various techniques and methods used to create 3D paintings. One technique is to use shading and shadows to create the illusion of depth and dimension. This can be done by employing value (light and dark) in a gradual way to show form and using edges (hard, soft, fuzzy, lost) to support forms coming forward and falling away from the viewer. Another technique is to use cast shadow, where a light source projects an image on a flat surface, and the cast shadows are then used to create a 3D effect. Additionally, digital or graphic designers can use 3D software to bring their ideas from concept sketches to a three-dimensional virtual reality. Once a complete computer-generated render is created, they may use a 3D printer or mold it using materials such as plastic or metal.
Some artists who are known for their work in 3D paintings include Yayoi Kusama, who often uses bright colors and patterns in her psychedelic paintings. David Kracov is another artist known for his 3D wall sculptures made using metal materials. His artworks are displayed on walls like traditional 2D paintings but seem to jump out of the surface.
In terms of terminology, there is some debate over the specific term for a 3D painting. Some people refer to it as "rendering", "modelling", "form", "depth", "sculpting", or "shading". The term "relief" has also been used to describe 3D art on a canvas.
