INTRODUCTION• WHAT ARE RASTER IMAGES?Images Generated on Raster Scan Display

Devices.These Images are formed by illumination of

spots called as PIXELS.Each pixel contain information about each

Colour ,Position and its brightness

INTRODUCTIONThus, Raster Images are collection of a large

number of pixels.These Pixels are stored in BIT MAP of the

image in the System Memory which is then viewed by the video controller.

The Figure shows the Scenerio:

INTRODUCTION

RASTER ANIMATION• WHAT IS RASTER ANIMATION?When these such Raster Images when Played

in a Particular Sequence it is called as Raster Animation Sequence.

Each Raster Image is called as Raster Frame.Raster animation forms the more Realistic

Raltime Images.

RASTER ANIMATIONLet us take The Raster scan Display Generating

Raster Scan Image:

RASTER ANIMATIONFor Sequence of such Raster Images The Frame

Buffer in System Memory that Store the Bit Map is refreshed with a new bit map of new image that is to be displayed or Sequenced:

The Figure Shows The scenerio:

T1 s T2 s T2 s

RASTER ANIMATIONThe Following Figure shows 4 Raster images

where the Bitmaps are Loded one by one within the time t1,t2,t3.t4 microseconds

The time when the new Bit map Is decide by the user to Create the Animation.

TYPES RASTER ANIMATIONThere are broadly 2 Types Of Raster Animations:

RASTER ANIMATION

TRADITIONAL MODERN

TYPES OF RASTER ANIMATION

TRADITIONAL RASTER ANIMATION:Used low Detailed Animation using Sprite

SheetsSprite Sheets allowed the Removal of any object

that was not needed, but Disturbed the Animation Sequence.

TYPES RASTER ANIMATIONSPRITE SHEET:

TYPES OF RASTER ANIMATION

MODERN RASTER ANIMATION:Each animation frame is either scanned into a computer.Programming languages such as Flash, HTML and Java is

Used.Generate 2-D animations based on user input events,

such as mouse clicks or keystrokes.Scaled to fit any window with predefined Resolution.

EXAMPLES OF RASTER ANIMATION

VECTOR VS RASTER ANIMATIONVector animation store image information as a

sequence of points whereas raster animation stores information in form of PIXELS.

Vector Animations does not provide much clarity of image than the Raster Animation generates Real-time Images

Raster Animations are rendered at High Resolutions whereas Vector Animations at Low Resolution.

VECTOR VS RASTER ANIMATIONThe Figure Shows The Difference:

APPLICATIONS3D and 2D Animation RenderingMesh FilteringReal Time Game Designing and GraphicsCartoon Animation to Make ReailisticAnimation Movies

ADVANTAGESGives the animator control over appearance of an

imageRaster Animation Uses less MemoryFlexible and can Remove Selective Objects in

Animation Sequence.Supports 3D object Animation.

DISADVANTAGESRaster files are much LargerBiggest Problem is of Scaling leads to

Multiplication of Each pixel which generates a Blocky pixelated image.

Costly Hardware Devices are Required to Render.
