• The goal
  • 2D geometry
  • Linear transformations
  • 2D affine transformations
  • Homogeneous coordinates
  • Wait a second, it is forbidden to divide by zero!
  • A composite transformation
  • Wait a minute, may I touch this magical bottom row of the 3x3 matrix?
  • Time to work in full 3D
  • Let us sum up: the main formula for today
