AHGC
- 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
- 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
- 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
- Imposition
- orderering pages so that they will read
correctly when trimmed and bound
- Text
- Serif
- small decorative pieces of the letters
- eg. Times New Roman
- Sans Serif
- typeface with no serifs
- Helvetica
- 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
