History (CG)
• They made Computer
Graphics affordable
• Before PCs, graphics
workstations cost hundreds
of thousands
– Evans&Sutherland
– Apollo
– Silicon Graphics (SGI)
• Today, fast graphics cards
allow real time parallel
processing
• Rendering is done on
rendering farms: networked
PCs

• In the 60s and early 70s, light reflection properties
were modeled for their use in computers
– Shading algorithms
• Flat shading
• Phong shading

• Complex modeling programs
were developed in the 80s
• Allowing more and more
realistic renderings
– Raytracing
– Radiosity

History (CG)
• Nowadays there is a whole set
of options for doing graphics on
computers
• All one needs:
– A fast PC
– For complex renderings a
cluster of PCs
…and of course some good
software
• Every designer knows:
– 3D Max
– Maya
– … all possible variations of
software
– Most of them very expensive
• We don’t have much money,so
we will use Open Software:
– Blender
