When was cgi created

Overview

Computer-generated imagery (CGI) refers to the use of computer graphics to create or contribute to images in art, video games, films, and television. The roots of CGI trace back to the early 1960s, when researchers began experimenting with digital image creation and manipulation.

Since its inception, CGI has revolutionized visual storytelling, enabling filmmakers and designers to create realistic and fantastical visuals previously impossible with practical effects. The evolution of CGI has been driven by advances in computing power, rendering algorithms, and creative innovation.

• 1960: The term computer graphics was coined by William Fetter, a graphic designer at Boeing, marking the conceptual birth of CGI.
• 1963: Ivan Sutherland developed Sketchpad, an early graphical user interface that laid the foundation for interactive computer graphics.
• 1972: Edwin Catmull created the first 3D CGI film, a short animation of his hand, at the University of Utah.
• 1973:Westworld became the first feature film to use 2D CGI, displaying pixelated images of a robot's point of view.
• 1976:Futureworld introduced 3D CGI models in film, featuring a computer-generated hand and face.

How It Works

CGI relies on complex software and hardware systems to generate visual content. The process involves modeling, texturing, lighting, animating, and rendering digital assets into final images or sequences.

• Modeling: Artists create 3D objects using polygons or NURBS; software like Maya or Blender allows precise control over shape and structure.
• Texturing: Surfaces are given color, roughness, and reflectivity; texture maps simulate materials like skin, metal, or fabric.
• Animation: Keyframe or motion-capture techniques bring models to life; Disney and Pixar pioneered character animation in CGI.
• Lighting: Virtual lights mimic real-world physics; ray tracing calculates light paths for realistic shadows and reflections.
• Rendering: The final image is computed from 3D data; render farms process complex scenes over hours or days.
• Compositing: CGI layers are combined with live footage; After Effects and Nuke integrate elements seamlessly.

Comparison at a Glance

CGI has evolved significantly from its early days, both in technical capability and application scope.

Each decade brought exponential improvements in speed, realism, and accessibility. From the hand animation in 1972 to today’s AI-assisted rendering, CGI continues to redefine visual media.

Why It Matters

CGI has transformed entertainment, science, and education by enabling visualization beyond physical limits. Its impact spans industries, from blockbuster films to medical simulations.

• Film industry:Over 90% of major studio films now use CGI for effects, set extensions, or full characters.
• Video games: Modern titles like The Last of Us Part II rely on CGI-quality assets for immersive experiences.
• Medical training: CGI models simulate human anatomy, improving surgical preparation and education.
• Architecture: 3D renderings allow clients to walk through virtual buildings before construction begins.
• Advertising: Brands use CGI to showcase products in dynamic, cost-effective ways without physical shoots.
• Scientific visualization: CGI helps interpret complex data, such as climate models or molecular structures.

As computing power grows and AI tools emerge, CGI will continue to expand creative and practical possibilities across global industries.
