CGI full form is “Computer Generated Imagery.” This term refers to the application of computer graphics to create visual elements, scenes, or images in various media, such as films, video games, advertisements, and more. It involves the use of specialized software and techniques to generate realistic or fantastical visuals that would be difficult or impossible to achieve using traditional methods. CGI plays a significant role in modern visual storytelling, enhancing visual effects and creating immersive digital environments. In this article we will tell you about “CGI Full Form: Evolution, Working , Applications and more”.
Evolution of CGI
| Era | Characteristics | Key Developments |
|---|---|---|
| 1960s-1970s | Basic computer graphics, wireframe models. | – Ivan Sutherland’s Sketchpad. “Star Wars” wireframe graphics. |
| 1980s | Advancements in 3D rendering, early computer-generated images. | – “Tron” showcases early CGI effects.Pixar founded. |
| 1990s | Rise of realistic rendering, significant growth in usage. | – Jurassic Park’s lifelike dinosaurs. “Toy Story” first feature-length CGI film. |
| 2000s | Expanding applications, enhanced visual effects. | – The Matrix trilogy’s groundbreaking effects. Rise of video game CGI. |
| 2010s-Present | Photorealism, integration with live action, VR/AR applications. | – Marvel Cinematic Universe’s seamless CGI integration. Virtual reality CGI experiences. |
How CGI Works
- Modeling: CGI begins with creating a 3D digital model of objects, characters, or environments using specialized software.
- Texturing: The model is given a surface appearance by applying textures, colors, and details to mimic real-world materials.
- Rigging: Characters and objects are given digital skeletons (rigs) that allow animators to control their movements realistically.
- Animation: Animators manipulate the rigged models, creating movements frame by frame to bring them to life.
- Lighting: Virtual lights are placed within the scene, affecting how light interacts with objects, creating shadows and highlights.
- Rendering: The scene is processed, and each frame is calculated for lighting, shading, and other visual effects.
- Special Effects: Various effects like particle systems (fire, smoke), simulations (cloth, water), and physics are added.
- Compositing: CGI elements are integrated with live-action footage or other CGI elements to create a cohesive scene.
- Post-Processing: Final adjustments are made to colors, contrast, and visual effects for a polished look.
