What is Computer Animation?

Any computer-based computation used in

producing images intended to create theperception of motion [Computer Animation Complete,2010]

Sequence of computer-generated images[Johan Cohen]

Involves creating moving images with the

help of computers.[www.TheArtCAreerProject.com]


4/26

The word animation came

from the wordanime

which means

life.

Did you know?


5/26

What is Computer Animation?

A series of digital

still images thathave gradually or

drastically

transforming

properties to

visually present

motion.


6/26


Medical Animation

Demonstration of how pharmaceutical

drugs work in the bloodstream and body;

Interactive models of the human body on

both macroscopic and microscopic, interior

and exterior scales; Interpretation of patient data into 3D visual

images;


7/26


Medical Animation

Creation of instructional materials for

medical students;

Demonstration of surgical techniques in

virtual representation;

Breakdowns of how medical equipment/proposed medical equipment will work.

Architecture and Landscaping

create 3D models of buildings from

blueprints are nearly indispensable when itcomes to planning construction

details such as measurements, materials,

and placements of beams, supports,windows, and other design elements can

all be worked out in a three-dimensional

environment, and can help to predict any

potential pitfalls as well as estimate the

to demonstrate how a prospective

building's materials might hold up or cavewhen under stress from various forces, as

well as predict how much tension and

weight supports can handle


11/26


Mechanical Animation

to create virtual models of proposed

products and mechanical designs

parts can actually be fitted together in a

realistic manner, and their functions tested

measurements can be planned down to thesmallest unit, with more accuracy than

pencil-and-paper diagrams can often

provide


12/26


Mechanical Animation

eliminate a lot of problems that would

normally require extensive physical testmodels and experimentation (Anything

from gear fitting tests to vehicle crash tests

can be simulated online using real-time

simulacrum of natural forces and materials)

Computer Graphics and Animation

Computer Graphics

Visual presentations created using

computers

Disneys Chip/Dale and The Incredibles


14/26

Types of Graphics according to

Composition

Raster Graphics/Bitmapped

Images that are created using dots (pixels)


15/26


Composition


16/26


Composition

Vector Graphics

Images that are created using

mathematically computed lines and shapes


17/26


Composition


18/26

Raster vs. VectorRaster

Used for real-life imagery

Recommended for digital camera

shots

Stores millions of colors

Vector

Used for cartoon-like images

Recommended for animation

Sustains quality of the images

even when transformed


19/26


Dimensions

Two-Dimensional Graphics

Created using a coordinate system with

two axis and two planes

Consist of points that has x

and y coordinates


20/26


Dimensions

Three-Dimensional Graphics

Created using a coordinate system with

three axis and three planes

Consist of points that has x, y

and z coordinates


21/26


22/26

Types of Coordinate Systems

Cartesian Coordinate System

Polar Coordinate System

Left-Handed Coordinate System

Right-Handed Coordinate System


23/26

The Polar Coordinate Systems

Properties: Polar Axis, Pole

Example Coordinates:

A(5,30)

B(-7, 60)

C(9, -90)D(-8, -45)


24/26

How to Plot Points in a Polar Coordinate

SystemP (r, ) - where r is the radius vector

- is the polar angle

R is + (positive) if measured from the pole along theterminal side of

R is - (negative) when taken in opposite direction

is + (positive) if measured counter clockwise

is - (negative) when measured clockwise
