This script converts hexagonal isotropic (possibly non-totalistic) CA rules[1]
into the equivalent MAP rules[2].  It runs under both Python 2 and Python 3, and
can be used either as a stand-along script (with the rules given as command line
arguments) or as a Golly plug-in.

About YUV formats

First of all: YUV pixel formats and Recommended 8-Bit YUV Formats for Video Rendering. Chromium's source code contains good documentation about those formats too: chromium/src/media/base/video_types.h and chromium/src/media/base/video_frame.cc (search for RequiresEvenSizeAllocation(), NumPlanes() and those kinds of functions).

YUV?

You can think of an image as a superposition of several planes (or layers in a more natural language). YUV formats have three planes: Y, U, and V.

Y is the luma plane, and can be seen as the image as grayscale. U and V are reffered to as the chroma planes, which are basically the colours. All the YUV formats have these three planes, and differ by the different orderings of them.

(* Conway's life rules *)
rule = {224, {2, {{2, 2, 2}, {2, 1, 2}, {2, 2, 2}}}, {1, 1}};

(* hashlife algorithm *)
lastId = 1;
h[x_] := (lastId = lastId + 1; h[x] = lastId; q[lastId] = x; lastId);
q2[i_] := ArrayFlatten[Map[q, q[i], {2}]];
step[i_, d_] := step[i, d] = Block[{
    i2 = q2[i],
    half = Map[step[h[#], d - 1] &, Partition[#, {2, 2}, 1], {2}] &},

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git
