Raster animation is created by displaying a sequence of raster images rapidly to create the illusion of motion. Each raster image is stored as a bitmap in system memory and contains information about individual pixels that make up the image. By refreshing the frame buffer with a new bitmap, raster animation is created. There are two main types - traditional using sprite sheets and modern using programming languages. Raster animation provides more realistic images than vector animation but requires more memory and processing power. It is used for applications like 3D/2D animation, games, and movies.

3. 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

4. INTRODUCTION
Thus, 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:

5. INTRODUCTION

6. 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.

7. RASTER ANIMATION
Let us take The Raster scan Display Generating
Raster Scan Image:

8. RASTER ANIMATION
For 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:

9. T1 s T2 s T2 s

10. RASTER ANIMATION
The 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.

11. TYPES RASTER ANIMATION
There are broadly 2 Types Of Raster Animations:
RASTER
ANIMATION
TRADITIONAL MODERN

12. TYPES OF RASTER ANIMATION
TRADITIONAL RASTER ANIMATION:
Used low Detailed Animation using Sprite
Sheets
Sprite Sheets allowed the Removal of any object
that was not needed, but Disturbed the
Animation Sequence.

13. TYPES RASTER ANIMATION
SPRITE SHEET:

14. 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.

19. VECTOR VS RASTER ANIMATION
Vector 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.

20. VECTOR VS RASTER ANIMATION
The Figure Shows The Difference:

25. APPLICATIONS
3D and 2D Animation Rendering
Mesh Filtering
Real Time Game Designing and Graphics
Cartoon Animation to Make Reailistic
Animation Movies

26. ADVANTAGES
Gives the animator control over appearance of an
image
Raster Animation Uses less Memory
Flexible and can Remove Selective Objects in
Animation Sequence.
Supports 3D object Animation.

27. DISADVANTAGES
Raster files are much Larger
Biggest Problem is of Scaling leads to
Multiplication of Each pixel which generates a
Blocky pixelated image.
Costly Hardware Devices are Required to Render.
