1. Vec & Bit

   • Vector
     • Raster Images
     • Pixels in a grid
     • contains specific colour information
     • single image made up of thousands of pixels
     • Pixel only clear when magnified
   • Bitmap
     • Individual scalable objects
     • Mathematical Equations
     • Allows them to render at the highest quality
     • Lines, cureves and shapes with editable attributes eg. colour and full
     • can be transformed using nodes
   • vectors > bitmap
     • vectors can be scaled and skewed without losing quality
     • but a bitmap will loose its map of bits

2. Lighting

   • Distance
     • Emits uniform parallel rays of light in one direction
     • Intensity does Not deminish over distance
     • Direction more important than location
     • Even objects 'behind' are lit
     • Stimulating sunlight
   • Spot
     • Emits light in a directional cone
     • direction and size can be specified
     • Intensity deminishes over distance
     • Hotspot and falloff angles
       • Specify how light deminishes along the edge of a cone
     • Maximum illumiation surrounded by lesser intensity
   • Point
     • Radiates light from all directions
     • Intensity deminishes over distance
     • Useful for simulating a lightbulb

3. Printing

   • Lithography
     • Advantages
       • Most cost efficient and fastest method
       • able to cope with more than normal 4 colours
       • Cheapest method for producing high quality printing
       • Concistent high quality image
     • Disadvantages
       • Small quality jobs not cost affective
       • plates must be properly cared for
   • Flexography
     • Advantages
       • Prints on wide verity of subtrates
       • Millions of impressions can be made
       • can print more than 10 colours if multiple stations are used
     • Disadvantages
       • Not cost affective for smaller prints
       • Not suitable for outdoor use
       • inks fade in UV light
       • halftones and small text tend to not print well as ink tends to spread

4. Imposition

   • orderering pages so that they will read correctly when trimmed and bound

5. Text

   • Serif
     • small decorative pieces of the letters
       • eg. Times New Roman
   • Sans Serif
     • typeface with no serifs
       • Helvetica

6. 3D Modelling

   • Boolean Intersection
     • Allows user to create composite solid from common volume of two overlappong solids
   • surface revolutions
     • A line or series of lines revolved about an axis leaving only a surface shape to the 3D item
   • Solid primative
     • Any standard 3D shape
   • Ruled surface
     • Constructs a polygon mesh representing the ruled surface between two curves
   • Union
     • Union allows the user to combine the total volume of two or more solids into a composite object
