the creation of animation.
Introduction
2D ANIMATION 3D ANIMATION

5. Video games cartoon Mobile phones

7. • Steps for designing animation sequences.
1. Storyboard Layout
2. Object definitions

4. Generation of in-between frames

13. Amorphium Art of illusion
• Animation software provide basic
functions to create animation and
process the individual object.
FUNCTIONS
Manipulate data object
database.
Motion generation.
Object rendering.

14.  Real-time animations can be generated using
raster operations.

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.
