BTEC Level 3 Unit 11: Digital Graphics and Animation - Learning Aim A Complete

This full lesson covers the following topic areas;

Learning aim A: Investigate the purpose and principles of digital graphics and
animation

A1 Digital image representation
Characteristics, application and implications of using digital data to represent digital images.

• Raster images:

  • 2D arrays
  • dimensions
  • sampling
  • colour modes
  • bit depth
  • resolution
  • compression (lossy, lossless).

• Vector images:

  • geometrical primitives (points, lines, curves, polygons)
  • paths
  • nodes
  • voxel.

A2 3D image representation
Principles and application of representing 3D images in digital format.

• Coordinate systems:
  • left- and right-handed
  • local
  • 3D world
  • 3D viewport
  • camera
  • geometrical primitives (points, lines, voxel).

A3 Digital animation techniques
Characteristics, application and implications of using digital animation techniques to create and process 2D and 3D animated images.

• Key frames.
• Tweening.
• Motion capture.
• Wire framing.
• Coordinate systems (2D and 3D).
• Environmental physics.
• Behavioural animation.

A4 Uses and applications of digital graphics and animation
Uses and applications of digital graphics and animation and the effect on content, format and characteristics.

• Target audience.
• Purpose, e.g. education, entertainment, illustration.
• Target platform.
• Target medium, e.g. digital, print.
• Interactivity.
• Legal and ethical considerations applicable to the equivalent legislation in England, Wales and Northern Ireland, e.g. privacy, security, use of content created by others.
