Computer-generated imagery (CGI) and 3D animation are often used interchangeably, but they are not the same thing. While both involve the use of computers to create visual effects, they have distinct differences.
In today’s blog post, we will explore the differences between CGI vs 3D animation and why it matters.
What is CGI?
Computer-generated imagery (CGI) is a broad term encompassing the application of computer graphics to create visual elements or entire scenes in films, television shows, video games, and other forms of media.
CGI uses specialized software and powerful computers to generate realistic and visually stunning images that may be difficult or impossible to achieve through traditional methods.
Through the use of this technology, filmmakers and content creators are able to produce fantastical landscapes, lifelike characters, and intricate special effects, seamlessly blending digital and live-action elements to enhance their storytelling and audience engagement.
CGI employs techniques such as 3D modeling, texturing, rendering, and animation to create virtual environments, characters, and objects. Overtime CGI has become an integral part of modern media production, allowing creators to bring their visions to the screen with never-seen-before realism and creativity.
What then is 3D Animation?
3D animation, on the other hand, is a specific type of CGI that involves the creation of animated characters, objects and environments using computer software. 3D animation is often used in movies, television shows, and video games to create lifelike characters and immersive environments.
Unlike traditional 2D animation, where characters and scenes are drawn on a flat surface, 3D animation uses computer-generated graphics to generate objects and characters with depth, volume, and realistic proportions.
This process typically begins with the creation of a 3D model using specialized software, defining the shape and structure of the characters or objects. Animators then manipulate these models to create movement by adjusting their positions, orientations, and attributes over time.
Once the 3D models are set up, the animation process involves rigging, which is attaching a virtual skeleton to the model to control its movement, and animating the characters by manipulating the skeleton. Lighting, texturing, and rendering are additional steps that add realism to the final output.
3D animation is widely used in various industries, including film, television, video games, and advertising, to bring characters and scenes to life in a visually compelling and dynamic way.
