Computer-generated imagery (CGI) is visual art made with computer software instead of, or alongside, traditional tools. In Intro to Art, it shows up as a major form of new media art, especially in digital images, animation, and 3D scenes.
Computer-generated imagery, or CGI, is art made with computer software to create still images, moving images, or entire digital scenes. In Intro to Art, the term usually comes up in the new media and digital art unit, where you look at how artists use technology as part of the creative process, not just as a tool for editing after the fact.
CGI can be simple or extremely complex. A basic 2D image might be built from digital drawing, layering, and compositing. A 3D image usually starts with a modeled form, then adds texture, lighting, shadows, and camera angles so the final image feels like something you could step into. That is why 3D CGI often looks more realistic than flat digital art, even when the whole scene is invented.
A big reason CGI stands out in art history is that it changes what counts as an image. Traditional art often depends on paint, clay, film, or ink, while CGI can create a visual from code, a digital brush, or a 3D mesh. The result can imitate photography, but it can also do things real cameras cannot, like show impossible creatures, fantasy worlds, or a building before it exists.
In Intro to Art, you are not just naming CGI as “computer-made pictures.” You are usually thinking about how it is constructed and what that construction does. Is the image meant to look photorealistic, stylized, abstract, or animated? Does it blend with other media, like in a film sequence, a game environment, or a virtual reality piece? Those choices affect how the viewer reads the work.
CGI also sits inside the bigger story of new media art. It reflects a shift toward art that is interactive, digital, and often collaborative. One artist might sketch the concept, another might model the forms, and another might handle rendering or motion. That process makes CGI useful for understanding how contemporary visual culture is made, shared, and experienced.
Computer-generated imagery matters in Intro to Art because it shows how digital tools changed the materials and methods of art-making. Once you understand CGI, you can better identify when an artwork is built from virtual space, when it imitates reality, and when it uses technology to create effects that older media could not easily produce.
It also helps you compare new media art to more traditional forms. A digitally rendered landscape may borrow ideas from painting, like composition and color, but it uses light, texture, and perspective in a different way. That comparison often comes up when you analyze how an artwork creates mood, depth, or realism.
CGI is a useful term for reading contemporary visual culture too. You see it in films, games, ads, architecture renderings, and virtual reality, so it connects art class to the images you already encounter every day. In critique or discussion, CGI can raise questions about realism, authorship, and whether a work feels handmade, digital, or somewhere in between.

3D modeling is often the starting point for CGI. Instead of drawing only a flat image, you build a digital form with height, width, and depth, then add surfaces, lighting, and camera views. In Intro to Art, this helps you see how digital sculpture-like structures become finished images or animated scenes.
Animation
Animation uses a sequence of images or digital movements to create the illusion of motion, and CGI is a major way animation is made today. A still CGI image and a CGI animation may use the same software tools, but animation adds timing, movement, and change over time. That difference matters when you analyze a video or film clip.
Render
Rendering is the step where a computer turns a digital scene into the final image you actually see. In CGI, rendering controls how light, shadows, textures, and reflections appear, which is a big part of whether the work looks realistic or stylized. It is the bridge between the constructed model and the finished visual.
augmented reality art
Augmented reality art combines digital elements with the real world through a screen or device, while CGI creates the imagery itself. They overlap because both depend on computer-generated visuals, but augmented reality places those visuals into live space. In class, this comparison helps you separate digital image-making from digital overlay and interaction.
generative art
Generative art is made using systems, rules, or code that help produce the final image, and it can overlap with CGI when computers are doing a lot of the visual construction. The difference is that generative art often emphasizes the process or system, while CGI usually emphasizes the finished visual result. That distinction matters in contemporary art discussions.
A quiz question might show you a digital image or film still and ask you to identify whether CGI is being used, or to explain how the artist creates depth, realism, or fantasy effects. In a short response, you may need to connect CGI to new media art, 3D modeling, or rendering rather than just calling it a computer picture.
On image-analysis prompts, describe the visual evidence, such as smooth surfaces, impossible lighting, repeated digital textures, or characters and environments that do not exist in real life. If the prompt asks about process, trace the steps from modeling to rendering. If it asks about meaning, explain how CGI changes the viewer’s sense of realism, scale, or immersion.
Computer-generated imagery is art made with software, and in Intro to Art it belongs to the new media and digital art unit.
CGI can be 2D or 3D, but 3D CGI usually adds more depth, light, and realism because the image is built in virtual space.
Artists use CGI when they want effects that are hard to make with traditional media, like fantasy worlds, digital creatures, or impossible camera views.
CGI is not only for movies and games, because it also shows up in architecture, medicine, education, and other visual fields.
When you study CGI, focus on how the image is constructed and how that construction changes the way you read the artwork.
Computer-generated imagery, or CGI, is visual content created with computer software instead of only traditional art materials. In Intro to Art, it usually appears as part of new media and digital art, where artists use digital tools to build images, scenes, animation, or virtual environments.
Not exactly. CGI is the digital image-making process, while animation is motion over time. A CGI image can be still, and CGI can also be used to make animation, so the two overlap but do not mean the same thing.
You might analyze CGI in film stills, digital artworks, game imagery, or virtual reality pieces. The main job is to identify how the image was built, what makes it look realistic or stylized, and how digital methods change the artwork’s meaning or effect.
3D modeling is the act of building a digital form, while CGI is the broader category of computer-made imagery. A 3D model often becomes part of CGI after it is textured, lit, rendered, and turned into the final image or animation.
