Intro I extracted my mate’s (approximately 60×60 pixel) face from a Facebook picture, and overlaid it onto a depth-map for a similarly shaped face, then used a custom python script to create a 3d wavefront model of his face, and an accompanying .mtl file for the texture. I will create a post soon properly dissecting […]

Python Packing Streams of Arbitrary LengthWhen starting out with IO and learning to efficiently read and write binary structures to and from Python most people will confront the problem of packing a string or list into a structure. Variations of this question plague Stack Overflow, here are two quick examples:https://stackoverflow.com/questions/3753589/packing-and-unpacking-variable-length-array-string-using-the-struct-module-in-py, https://stackoverflow.com/questions/34117620/how-to-unpack-variable-length-data-in-python-struct I have a rather simple solution I decided to […]

Julia Blend (Animated Julia Sets)Draw Julia set animations by simply defining a 2d line though the complex plane. A Julia set is simply a recursive function or iterative process that takes the form z=z^2+cwhere the initial value of z is a complex number representing a point in 2d space, and c is any complex.The z argument is updated until […]

Drawing With GravitySimulation is a great way to learn new concepts. Whenever I’m confronted with some scary physics equation I can’t follow I usually try to find the equivalent concept in a syntax I know. In the following post I will covering a few loose simulations of Newtonian inspired gravity.It’s not true Newtonian gravity as I was […]

Extrema Compression (Part 2)Part 2 is on decompression, start with Part 1 Extrema Compression (Part 1)Decompression:Luckily for us the decompression phase is much simpler than the compression phase. It would have been simpler regardless but We create a new wave file for the output, we simply need to have a while loop read through the file five bytes […]

Python Model Sword MakerMake a variety of sword, knives, hammer/axes, polearms, and much more with only a few lines code. The code is split into 3 libraries:Mesh.py: Tools for processing triangle meshes. The triangle mesh is a list of triangles composed of 3 vertices, each with a corresponding colour (RGB from 0 to 1). Currently the library only […]

Human Readable Spectrum FilesXML based spectrum files and a Python class for reading, writing, and modifying them. I was hoping to put together a Javascript tool for visualising the Red-shift of different celestial phenomena over different distances.Sadly it didn’t take long to learn the dominant file format for spectra (.SPC) is binary encoded and pretty complex; as a […]

Extrema Compression (Part 1)ExtremaCompression is a low-loss compression method for audio.
Unlike MP3, OGG and other common standards the results still vary widely proptional to frequency.
Higher frequency oscillations will be encoded with minimal loss, but also minimal compression, while low frequencies will compress very small but the quality may deviate from the original product.

Python Particle Swarm OptimiserParticle Swarm Optimisers are ideal for fine-tuning the numerical variables of a given process/function/structure so long as you can define a way to measure how well it has performed.
