Projection method and corner points
Earlier I showed you how get the corner points of a quasiperiodic tiling. For the AmmannBeenker tiling see the posts “An easy way to quasiperiodic tilings” and “How to find these corner points of the tiles“. This is easy to … Continue reading

Setting up the coordinates
Computer technology determines the coordinates that processing uses. The distance between two pixels is the unit length and the origin lies at the upper left corner. This is not what we need in geometry and mathematics. Fortunately, processing has all … Continue reading

Iterative method for the AmmannBeenker tiling using “Vector”
In the earlier post “An efficient iterative method for the AmmannBeenker tiling” I briefly presented an iterative dissection of rhombs and triangles that gives the AmmannBeenker tiling. In the next post “Iterative method for the AmmannBeenker tiling – the code” I … Continue reading

class Vector
The basic element of geometry is a point or vector. We could use the PVector class of processing to work with vectors in 2 and 3dimensional space. However, this is not really efficient for 2dimensional vectors, because their zcomponent is … Continue reading
