a Ppt for level 3 btec creative media students. bitmaps and vectors

1. Digital 2-d Animation Techniques
Unit 34
• Learning outcome:
• 1.Understand the techniques of 2D animation.
• (P1, M1, D1)
• Starter:
• Recap on previous learning animation techniques

2. Traditional 2-d Animation Production Techniques
Unit 34
• What are we going to do today?
All of you will be able to define bitmap graphics and vector
graphics.
Most of you will be able to research and explain bitmap
graphics and vector graphics.

3. Traditional 2-d Animation Production Techniques
Unit 34
• Animation Techniques
• Illustrated Magazine Article: Thursday 15th November 2018
• For the first task you need to produce two separate articles, 1000 words
each.
• The first one needs to look at 2D animation, its techniques, history and
development to gain and show an understanding to help your decisions
when creating your own 2D animation production. To complete this task you
are required to produce an illustrated magazine article that explores the
history and techniques of 2D Animation.

4. Traditional 2-d Animation Production Techniques
Unit 34
• When you take a
photograph using a digital
camera or scan an image
from a magazine, you are
creating a bitmap
graphic. A bitmap
graphic is composed of
many tiny parts, called
pixels, which are often
many different colours. It
is possible to edit each
individual pixel.

5. Traditional 2-d Animation Production Techniques
Unit 34
• Bitmap images are pixel based this means that
an image is made up of a series of dots (pixels)
in a grid. When a bitmap image is enlarged it
looks ‘pixelated’ this is because each image
contains information about the colour to be
displayed.
• They have a fixed resolution and are unable to
be resized without losing quality. Common
bitmap formats are .jpg .gif .bmp .png The file
sizes of bitmap images tends to be a lot larger
than vector graphics.

6. Traditional 2-d Animation Production Techniques
Unit 34
• Vector graphics is the
creation of
digital images through a
sequence of commands
or mathematical
statements that place
lines and shapes in a
given two-dimensional or
three-dimensional space.
In physics, a vector is a
representation of both a
quantity and a direction at
the same time.

7. Traditional 2-d Animation Production Techniques
Unit 34
• Vector graphics are
created from
mathematical
formulas used to
define lines, shapes
and curves. Edited in
draw programs
Shapes can be edited
by moving points
called nodes (drawing
points)

8. Traditional 2-d Animation Production Techniques
Unit 34
• Vector graphics are created in graphics
packages and consist of shapes called objects.
• It is possible to edit each object separately, for
example, change the shape, colour, size and
position.
• Even if an object in a vector graphic is quite
large, it doesn't need a lot of computer memory.
Therefore the file size of a vector graphic is
often very small.
• Vector graphics are scalable - ie when you
resize them, they do not lose quality.

9. 2-d Animation Production Techniques
Unit 34
• Take this quiz
• Bitmap vs Vector quiz

10. 2-d Animation Production Techniques
Unit 34
• Bitmap or vector graphic?
• When deciding whether an image should be a
bitmap or vector graphic, you should ask
yourself the following questions:
• Does the image need to be resized?
• Does the image need to be drawn to scale?
• Do you need the image to look real?
• Do you have any restrictions on the file size?

11. Traditional 2-d Animation Production Techniques
Unit 34
• Task: Research bitmap graphics and
vector graphics for your 2d animation
article.
• Define each and state the differences.
• Write what the advantages and
disadvantages are of each.
• Research bitmap graphics and vector
graphics games characters.
