jsWire

Javascript wireworld engine, designed to run primes.wi as fast as possible. primes.wi downloaded from http://www.quinapalus.com/wires11.html

In principle it should run or be extensible to run any .wi file.

Description

Loading a File

The engine should be pointed at a file, and it will be loaded, displayed and run automatically.

Generation Engine

I did some experiments with asm.js and it did work but is currently disabled. Generations are stored in two 1 MByte areas in a 3 MByte heap allocated by the main program.

Wire world values are stored in the heap as unsigned 8 bit values.

Rendering

Currently there's three renderers:

1. wwRender

   This renderer simply copies a generation to a Javascript canvas. Rect by painful rect.

2. wwRenderChanged

   Renders only changed cells. This doesn't buy that much speed.

3. tjRender

   This is the incomplete as yet three js renderer. It works very very fast, but just renders bare luminance values directly from the byte heap.

Current Things to Work On

1. Fixing up the Three.js Renderer

   This needs to use a fragment shader that translates the Wire world values into colors passed as uniforms.

2. Generation Counter

   Need to add a generation counter and logic to estimate how many generations can be calculated between 60 fps updates.

3. Texture-based Simulation

   It should be simple to ping-pong generations between two textures for really fast performance.
