Btec u 34 bitmap vs vector
- 1. Digital 2-d Animation Techniques Unit 34 • Learning outcome: • 1.Understand the techniques of 2D animation. • (P1, M1, D1) • Starter: Using the handout provided, in pairs; Identify the areas of your ‘comfort zone’
- 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. Some of you will be able to use Photoshop to design your own bitmap graphic character.
- 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 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 and are often reduces to compress the size of them.
- 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.

- 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.
