The first Academy Awards were handed out on May 16, 1929, not long after the advent of “talkies.” By 1930, enthusiasm for the ceremonies was so great that a Los Angeles radio station did a live, one-hour broadcast, and the Awards have enjoyed broadcast coverage ever number and types of awards have grown and changed over the years to keep up with the development of the motion picture industry.

Traditional Animation Keyframe Animation Interpolating Rotation 2001 Final Fantasy 1 Computer Animation Models have parameters - Polygon positions normals spline control points joint angles camera parameters lights color -n parameters define an n-dimensional state space -Values of n parameters point in state space Animation defined by path through state space -To produce animation 1. start at beginning of state space path 2. set the parameters of your model 3. render the image 4. move to next point along state space path repeat 2 - Path usually defined by a set of motion curves one for each parameter Every animation technique reduces to specifying the state space trajectory the state space will change with the technique Animation vs. Modeling Modeling and animation are tightly coupled - Modeling what are the control knobs and what do they do -Animation how to vary them to generate desired motions 2 Overview Animation techniques -Traditional animation frame-by-frame -Keyframing -Procedural -Behavioral -Performance-based motion capture -Physically based dynamics Modeling issues -Rotations -Inverse kinematics Traditional Cel Animation Film runs at 24 frames per second fps -That s 1440 pictures to draw per minute -1800 fpm for video 30fps Productions issues - Need to stay organized for efficiency and cost reasons - Need to render the frames systematically render farms Artistic issues - How to create the desired look and mood while conveying story -Artistic vision has to be converted into a sequence of still frames - Not enough to get the stills right--must look right at full speed Hard to see the motion given the stills Hard to see the motion at the wrong frame rate
