Computer animation is animation created with digital software. It encompasses both 2D (vector and raster) and 3D (CGI) techniques, where movement is generated by keyframing, interpolation, procedural systems, physics simulation, and motion capture.
The medium emerged from early computer graphics research and matured into a full production pipeline used for films, television, games, web series, and scientific visualization. Modern computer animation integrates modeling, rigging, texturing, lighting, rendering, and compositing, supported by powerful rendering engines and real‑time game technologies.
Pioneering work at Bell Labs, the University of Utah, and research groups in the U.S. and Europe established computer animation as an outgrowth of computer graphics. Experimental films using plotters and vector displays demonstrated the feasibility of algorithmic motion and synthetic imagery.
Dedicated graphics hardware, shading languages, and the first commercial CGI shorts brought computer animation into broadcast and advertising. Studios and VFX houses began integrating digitally animated elements with optical and later digital compositing.
The 1990s marked computer animation’s mainstream breakthrough with the first fully computer‑animated features and widespread use of CGI in live‑action films. Toolchains standardized around modeling, rigging, and physically based rendering, while character animation adapted classical 12 principles to digital workflows.
Web‑native formats (e.g., Flash) expanded 2D computer animation on the internet. Feature studios refined global illumination and simulation, while game engines introduced real‑time animation, procedural systems, and motion capture to interactive media and machinima.
Path‑traced rendering, real‑time ray tracing, virtual production, and AI‑assisted workflows (retargeting, inbetweening, denoising) have accelerated production. Computer animation now underpins most contemporary animation, VFX, and immersive content, blending cinematic quality with real‑time interactivity.
Start with a clear concept, script, and storyboard. Create an animatic to establish timing, staging, and camera language before committing to detailed production work.
Model characters, props, and environments (3D) or design vector/raster assets (2D). Build clean topology suitable for deformation, and develop UVs and textures using PBR workflows to ensure predictable shading.
Rig characters with robust skeletal controls and deformation systems (blendshapes/corrective shapes). Animate using the 12 principles (timing, spacing, squash & stretch, anticipation, arcs, etc.). Combine keyframing with procedural tools, constraints, physics, and motion capture when appropriate.
Light shots with physically plausible setups and motivated sources. Choose rendering strategies—offline path tracing for film quality or real‑time engines for interactivity. Composite passes (beauty, AOVs) to refine color, depth, and effects, and integrate VFX simulations (cloth, hair, fluids, destruction) as needed.
Common tools include Blender, Maya, Houdini, Cinema 4D, Unreal Engine, and Unity; texturing with Substance tools; compositing with Nuke or After Effects; and version control with shot/asset management. Maintain a consistent color pipeline (e.g., ACES) and use render farms or GPU clusters for efficiency.
Match performance and visual style to the project’s tone. For stylized looks, simplify shapes and rely on strong posing and timing. For realism, prioritize accurate physics, nuanced facial acting, and subtle secondary motion.
