What Is CGI Animation? How CGI Works in Movies and Games

CGI, or computer-generated imagery, is any visual content created with computer software, from still images and digital effects to fully animated 2D or 3D scenes. It has dominated modern film and game production for a long time because it simply makes physically challenging or even impossible scenes doable. CGI can make many productions more efficient by reducing repetitive manual work and allowing assets to be reused.

After reading this guide, you'll know what CGI is, how it's made, the software professionals use, how rendering works, what makes CGI look realistic, and why some CGI falls short.

What Is Stop Motion Animation? Types, History, and Famous Examples

Stop motion is an animation technique in which physical objects are photographed one frame at a time and shifted in tiny increments between shots. Played back in sequence, those frames create the illusion of smooth movement. The method dates back to 1898 and is still actively used in film, TV, and advertising today.

In this guide, we’ll talk about what stop motion is, different stop motion types, its rich history, stop motion in movies, how it’s made, and why we still see this age-old technique even in this new era dominated by CGI and AI tools.

Follow Through and Overlapping Action: The Animation Principle That Prevents Stiff Motion

Follow through and overlapping action are two core principles from the 12 basic principles of animation, and they exist to prevent motion from looking stiff or mechanical. Introduced by Disney animators, both describe how parts of a body or object keep moving after and around the main action, instead of starting and stopping all at once.

Stiff motion occurs when an object moves from one position to another at a constant speed and stops suddenly. In reality, body parts and objects slow down, overlap, and settle naturally rather than stopping instantly.

This guide covers how follow-through and overlapping action make animation more natural and the physics behind it. We’ll also talk about body hierarchy, material timing, and how all these concepts can be observed in popular films.

We’ll also be giving practical exercises for you, so you can master follow-through and overlapping action in your own work.

Smear Frames in Animation: How Animators Create Fast and Dynamic Motion

Animation is all about bringing still images to life, piecing frame after frame together to build the illusion of movement. While the concept sounds simple, creating believable motion requires careful control of timing, spacing, and transitions so that every action feels smooth and natural.

One of the common challenges both beginners and professionals face? Fast and dynamic movement.

One of the most effective techniques is smear frames. By briefly stretching or multiplying the appearance of a moving object between key poses, smear frames create the illusion of continuous motion while keeping the action clear to the viewer.

This technique is used in both 2D and 3D animation. After reading through this guide, you'll know what smear frames are, their importance, the best time to use them, when not to, practical tips, and more.

What Is a T-Pose in 3D Animation and Why It’s Still Used

In 3D animation, a T-pose is the neutral default stance of a humanoid character model: the figure stands upright with both arms extended straight out to the sides, forming a capital letter "T". It has been the standard since the 1990s, because it makes character modeling, rigging and animation far more efficient.

In this guide, we'll discuss what the T-pose is, how it helps with modeling and animation, and why it's still being used today.
