This document discusses various topics related to computer animation including its applications, design of animation sequences, animation functions, raster animations, computer animation languages, key frame systems, motion specifications, morphing, and tweening. It describes computer animation as the process of generating animated images using computers and discusses animation software functions for creating and processing animations. Animation techniques like raster operations, general purpose programming languages, direct and goal-directed motion specifications, kinematics, dynamics, and physically based modeling are also summarized.

16. • GENERAL PURPOSE LANGUAGES:
• C,C++,Pascal, or Lisp(control animation
sequences).

21. • Motions of objects specified as:
• Direct Motion Specification.
• Goal-Directed Systems.
• Kinematics and Dynamics.

26. • KINEMATICS:
• Motion parameters
• position
• velocity
• acceleration

28. • The forces that produce the velocities and accelerations
are specified(physically based modeling).
• It uses laws such as Newton’s laws of motion , Euler or
Navier -stokes equations.
