What To Know About CGI Works In Animation And Movies?

These days, computer-generated imagery, or CGI, is a common sight in films of all genres, including action, superhero, sci-fi, and fantasy epics. James Cameron’s Avatar was one movie that completely changed the way CGI was used. Avatar demonstrated the amazing potential of computer-generated imagery (CGI) in creating visually spectacular and immersive environments through its extensive use of motion capture technology.

But not every director has James Cameron’s money and experience, which means that many poorly rendered CGI films exist. It’s crucial to have a thorough understanding of CGI before anything else.

Through this blog you will receive a thorough introduction to CGI.

The Process of Creating CGI

Creating CGI involves several stages, each integral to achieving the desired end result.


During the pre-production phase, concept artists work closely with filmmakers to visualize the intended look and feel of the CGI elements. Storyboards and concept art are created to plan out the visual sequences and establish a coherent style.


Modelling is the process of creating virtual 3D objects or characters that will be used in the CGI scenes. Artists use specialized software to shape and sculpt the models, adding intricate details like textures and materials.

Texturing and Shading

Texturing involves applying surface details, colors, and textures to the 3D models. This process enhances realism by mimicking various materials like metal, skin, or fabric. Shading is the process of defining how light interacts with the surfaces, creating shadows, highlights, and reflections.


Making a virtual skeleton for characters or objects is known as rigging.. This skeleton allows animators to manipulate and move them convincingly. It involves setting up controls for body movements, facial expressions, and other physical attributes to bring the CGI elements to life.


Animation is where the magic truly happens. Animators use keyframe animation or motion capture techniques to breathe life into the CGI characters. The movements and behaviors are meticulously crafted to match the scenes and convey emotion.

Lighting and Rendering

Lighting is essential for creating a realistic look in CGI. Virtual lights are placed and adjusted to mimic real-world lighting conditions. Once the lighting is setup, rendering takes place, which is the process of converting the virtual scene into a final image or sequence of images. This computationally intensive process can take hours or even days, depending on the complexity of the scenes.


Compositing is the final step where all the elements, including live-action footage and CGI, are combined. This process ensures that the CGI elements seamlessly integrate with the live-action world, creating a cohesive and visually stunning final product.
