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 – the code
// needs class Vector and saveImage code // for details see Iterative method for the AmmannBeenker tiling using “Vector” Vector a,b,c; float f; void setup(){ size(600,600); f=1./(1.+sqrt(2.)); strokeWeight(2); smooth(); } void draw(){ noLoop(); a=new Vector(10,10); b=new … 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 code
// a class for twodimensional vectors, similarly as PVector //———————————————————— // // some important values float vectorSmall=0.0001,vectorSqrt05=sqrt(0.5); float vectorDiameter=8; color vectorColor=color(255); //rgb mode, for green // and here’s the class class Vector{ float x,y; // create a … 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
Saving images – example
// this shows how to use the code of the last post “Saving images – the code” // for a discussion see the post “Saving images” void setup(){ size(400,400); } void draw(){ noLoop(); rect(50,50,30,300); saveImage(); }
Saving images – the code
// this is for processing2 // use: “saveImage();” to save the screen image void saveImage(){ selectOutput(” where do you want to save the image ?”,”saveImageCallback”); } void saveImageCallback(File selection) { if (selection!=null) { String filePath=selection.getAbsolutePath(); … Continue reading
Saving images
I am using processing that you can download from processing.org. It is free but your donation is welcome. Processing is built on Java. With processing you can easily create interesting images with small programs. Once you have an image you … Continue reading
