Procedural animationThere are short films that are procedurally produced.
No feature length animation that is entirely procedural animation.
Procedural animation is often used as effect animation for live action films and 3D computer animations.
Feature length animation examplesSlide6
Keyframe is a drawing (image) of a key moment in an animation sequence, where the motion is at its extremeInbetweens fill the gaps between keyframes
Keyframe animationSlide7
In traditional animation, skilled animators draw keyframes; less experienced animators draw inbetweensIn 3D computer animations, animators set up parameter values for keyframes; software interpolates parameter values between keyframes for inbetweens
Every motion is created by animators
Keyframe animationSlide8
Different interpolation methods create different timing
Keyframe animation
Linear interpolation
Spline interpolationSlide9
What is motion capture?
Sampling and recording motion of humans, animals, and inanimate objects s 3D data
Data can be applied to 3D computer models
Motion capture animationSlide10
Faster to produce animation than keyframing (if an established production pipeline exists)Secondary motions and all the subtle motions are captured, providing more realism
Motion capture animationSlide11
Motion is generated by a procedure, a set of rulesAnimator specifies rules and initial conditions and runs simulation
Procedural animationSlide12
Provides more realism in natural phenomena than keyframingFrees animators from generating complex objects and keyframing a large number of objects
Procedural animationSlide13
Used for effect animation for traditional animation and live action films as well as for 3D computer animation
Procedural animationSlide14
A combination of keyframe animation, motion capture and/or procedural animation is often used to produce animations
