You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Jekyll also offers powerful support for code snippets:

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

Weeds & Trees (in Three.js)

Recently I have been working with the great 3D javascript library for webGL, three.js. After progressing through the various tutorials available I started looking for something interesting to implement using the library that wasn’t just making boxes.

Humboldt-University have a great section of Complexity Explorables which they describe as

A collection of interactive explorable explanations of complex systems in biology, physics, mathematics, social sciences, epidemiology, ecology and other fields….

One of the examples I particularly liked was using a simple iterative method to generate trees and branching patterns using the d3 library.

Obviously, this is in 2d, so I thought it would be interesting to see if this algorithym could be generalised to 3D tree generation.

Initially I did a straight port of the algorithm in the source code to three.js:

Obviously, that’s just a flat structure, and if you rotate it 90 degrees, it gives the game away;

My initial attempts at rotating in 3D were not entirely successful. Though for the “Tim Burton Tree”, it’s not actually far off what you would expect

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.
