The art of creating realistic CGI characters

HomeVisual Effects and Immersive Content


The use of computer-generated imagery (CGI) to create realistic characters has been a staple in the film industry for decades. From the iconic dinosaurs in Jurassic Park to the lifelike robots of Avatar, CGI has enabled filmmakers to bring their stories and characters to life with stunning realism. But creating realistic CGI characters isn’t easy. It requires a combination of technical skill, creative vision, and a deep understanding of the principles of character design. In this article, we’ll look at the art of creating realistic CGI characters and the techniques used to bring them to life.

Understanding Character Design

At the heart of every realistic CGI character is a good character design. A character’s design should reflect its personality, backstory, and purpose in the story. Cinematic techniques such as camera angles and lighting can also be used to give characters a unique look and feel. Character design should be approached from a variety of angles, from the physical features of the character to their wardrobe, mannerisms, and facial expressions.

Using Reference Materials and Models

When creating a realistic CGI character, reference materials such as photographs and video clips can be used to help capture the character’s desired look and feel. Reference materials can also be used to understand how light and shadows interact with a character’s features, and how to position the character in a 3D space.

In addition to using reference materials, it’s also helpful to create 3D models of the character. This allows the artist to experiment with different poses and facial expressions, as well as to adjust the character’s proportions and features.

Animating the Character

Once the character’s design is finalized, the next step is to animate the character. Animation is an integral part of creating realistic CGI characters, as it allows the character to realistically interact with the environment and other characters. Animators use a variety of techniques including keyframing, motion capture, and physics simulations to bring the character to life.

Rendering and Lighting

The final step in creating realistic CGI characters is rendering and lighting. Rendering is the process of creating the final image or video of the character, while lighting is used to create the desired look and feel of the character. Both of these elements are essential for creating realistic, believable characters.


Creating realistic CGI characters is an art form that requires a combination of technical skill, creative vision, and a deep understanding of the principles of character design. From reference materials and 3D models to animation and rendering, there are many techniques used to bring CGI characters to life. With the right combination of techniques, filmmakers can create stunningly realistic CGI characters that bring their stories to life.
