triangulr v1.0.3

triangulr

JavaScript class to generate maps of triangles. Test it on http://maxwellito.github.io/triangulr

Available on NPM : npm install triangulr

What is that?

triangulr is a little JavaScript class to build triangles walls. Completely random. In SVG: ready for HTML or Illustrator use. It give you a bit of flexibility to generate what you need: dimension, triangle size, ratio of mess and color

How to use it?

This is pure JavaScript, no jQuery required or other libraries. Only the simple triangulr.js in your page and you're ready to go. Here is an example:

var mySVG = new Triangulr (600, 500, 60, 0);
document.getElementById('myDiv').appendChild(mySVG);

Triangulr constructor needs these attributes:

• width integer : width of the SVG to generate
• height integer : height of the SVG to generate
• triangleHeight integer : original triangle height
• pointArea integer : area to place random points
• color function (optional) : function to generate a color for each triangle an object will be passed as parameter with information about the current triangle counter triangle numbermark
  • x column index
  • y line index
  • lines number of lines in the SVG
  • cols number of columns in the SVG
  • points array of triangle points

How it works?

The engine is quite simple to understand, even if at the start, it looks confusing to build this random triangles. To begin, we use the value given to the constructor to create a regular pattern with proper equilateral triangles. To do that, the script start by generate lines of dots. Then a second pass use these points to generate triangles, and also the color function to generate the color code. Then the last pass use the data to render it in a SVG DOM object.
