The Art of CGI Animation: Techniques and Trends

Creators are taking advantage of the growing technology these days to produce realistic effects and complex scenes. They especially use CGI effects in movies and video games to make animations look more realistic. Many people often ask how these animations are created and what tools professionals use to achieve such results. Additionally, most beginners who are unaware of this tech may think it is hard to master.

Therefore, this article will explain how computer-generated animation works, including its types and the software professional’s use. We will also discuss where this technology is commonly applied and what future trends we can expect. Since it also involves rendering, you will also discover a top cloud render farm service in this guide.

Part 1. What is CGI Animation?

It is a method used to create realistic moving images, including characters and environments, using digital animation tools. Unlike traditional techniques, which involve drawing animations by hand, this technique allows artists to design objects using tools. Besides movies, the CGI animation technique is widely used in video games and advertisements to create realistic visual effects without performing real-life stunts.

Since it produces scenes that would be difficult or impossible to film in real life, technology has become an important part of modern media. Professionals use advanced tools to design characters, simulate physics, and add lighting effects. As it is highly valued in the entertainment and advertising industries, the skill is a premium field for those interested in digital content creation.

Part 2. Types of CGI Animation

Now that you know what is computer generated animation, let’s discuss its types. While there isn’t a specific number of kinds, the following can be considered the top categories of this concept:

• 2D Animation: It involves creating flat images that move across the screen to give the illusion of motion. In cartoons and education videos, you can use this type to position characters and objects in different frames.
• 3D Animation: This type creates objects with depth, which makes them appear more realistic. Artists build digital models and add textures and movements to create realistic scenes for movies and games.
• Motion Capture: Unlike the above types, the motion capture technique records real human movements and applies them to digital characters. Special sensors track the actor’s movements, which are then transferred to a digital model for animated cartoons and games.
• Stop Motion Animation: The method involves capturing real objects frame by frame. During the process, artists move the objects slightly between each frame to create the illusion of movement.

Part 3. Key Techniques and Processes of CGI Animation

There are many techniques and processes that you can use to create your desired computer animation. For reference, you can find a few common processes used in this technique below:

• Modeling and Texturing: Artists start by creating digital versions of objects or environments. Afterward, they add surface details to models, like colors and fine details, to make objects more realistic.
• Rigging: This technique adds a digital skeleton to models to allow them to move. Animators create joints and controls so the character can be posed and animated easily.
• Animation: Once the model is rigged, animators make it move by adjusting the position of the model frame by frame. Doing so brings characters and objects to life in a realistic way.
• Compositing: It involves combining different visual elements into a single scene. Artists merge characters with backgrounds and effects to ensure all elements blend well.
• Rendering: This is the final step, where the animation is processed into a complete video. To create the final image, the computer calculates all the details, including lighting and textures.

Tips: Improve the CGI Animation Rendering Efficiency with Cloud Rendering 

Since rendering is the last step of the whole process, you must ensure it is performed efficiently to optimize your computer-generated animation. Rendering often requires higher resources to perform, and that’s why it is recommended to outsource it through Fox Renderfarm. This platform takes the load away from your computer and manages the resource-intensive rendering work using its online servers.
