Geo Numeracy

Things numeric relating to geometry and computational geometry that I have discovered.

• Coordinates and shapes

  Planar/Euclidean space. Basic coordinate notation. Creating basic geometric shapes and patterns.

• Irregular shapes

  Real world shapes are rarely regular. This section introduces the concepts of object array geometry.

• Side

  In, out, on, neither, both, left of, right of. Questions, questions.

• Buffer mysteries

  Everyone loves a buffer. Are they arcs? circles? or n-gons?

• Densify geometry

  Add points between vertices of polygon or polyline geometry.

• Dissolve those boundaries

  Removing boundaries between polygon geometries.

• Crossings

  A brief introduction to segment crossing, the notation and basic equations.

  Crossings, crossroads (1) and intersections... the non-math stuff too.

• Clipping

  Clipping looks so easy... right?

  All you have to do is cut stuff out and keep other stuff.

  Oh.. and keep stuff in order while you are doing it.

  We will see how you mastered intersections as the first step to clipping and erasing and the like.

• Clipping complex shapes

  Just when you thought you were grasping intersections and simple clipping.

(1) Crossroad Blues : Robert Johnson, Eric Clapton or Ry Cooder versions are all just fine as study music.
