Digital moving images from computer-generated 3D models—characters, environments, vehicles. Rendered through lighting and shading passes, fully controllable in post.
You're sitting at the editing bay, and a VFX supervisor shows you a raw render of a complex character animation — three seconds, one hundred fifty hours of render time. That's 3D Animation in the modern workflow: not a video recording of real objects, but the digital construction of geometry, movement, and light in a virtual scene. A character, a machine, an entire building — everything is created in the computer, voxel by voxel.
The pipeline follows proven patterns: concept and modeling (digital sculpting), rigging (virtual skeleton and controls for the animator), animation (keyframe setting or motion capture integration), texturing and shading (surface attributes), and finally rendering (final image calculation). For live-action integration, tracking is critical — the 3D scene must match the real camera, the shadows must be correct, the reflections must appear authentic. Motion capture significantly speeds up character animation; you ingest real-time data from actors, clean it up, and refine it in the computer. Skeletal motion is applied to your digital model — faster than keyframe work, but no less precise in fine-tuning.
In daily production, iteration is the core problem: every change to the rig, the lighting, or the camera necessitates new render passes. Therefore, work is done in passes — playblasts, draft renders with faster settings for early approvals, then final rendering with full complexity. Render farms (hundreds of processors in parallel) are standard, not a luxury. A feature film with 80 minutes can cost millions of render hours.
The difference from live-action lies in control: every pixel is calculable, changeable, repeatable. At the same time, the financial and time investment is immense — which is why 3D Animation is often treated as a special effect, not as the basis for entire scenes. Exception: fully animated films (studio animation), where the entire production logic is structured differently, with animators instead of actors and cinematographers.
