This is a quick experiment in using expressions in Maya to make a 3 dimensional cellular automata (live/die) system similar to Conway’s Game of Life.
Here are the source files: cell.zip The files contain a maya file with one cell and the attached expression. The other is a MEL script to create a three dimensional grid of the cell. Simply select the cell and run the script. the cell also has a number of custom attributes. To get everything started select one of the newly created cells and set its Timer attribute to 1 then play the timeline. To reset everything set all of the new cells Timer attribute to a negative number. Start off simple with a 6x6x6 volume. The file gets heavy pretty quick!
