LifeViewer supports:

Depending on the rule family it supports Moore, hexagonal, von Neumann, triangular, Circular and Margolus neighbourhoods and also bounded grids.

Native support for BSFKL, Extended Generations and deficient rules is also planned.[1][2][3]

LifeViewer features:

  • Smooth non-integer zoom with anti-aliasing and rotation.
  • Colour themes with cell history and longevity.
  • Square, hexagonal and triangular grid displays.
  • Pseudo 3D layers and stars.
  • Multiple ways to automatically track patterns with the camera as they evolve.
  • Script language that allows many features to be customized including Waypoint animations.
  • Support for multiple embedded LifeViewers and/or a single popup LifeViewer.
  • Ability to step back to earlier generations for all patterns and reverse playback for reversible Margolus and PCA patterns.
  • Random pattern and rule generation.
  • Pattern annotation with Labels, Arrows, Lines and Polygons.
  • Programatically pasting cells onto the grid at defined intervals (for example: glider injection).
  • Identification of oscillator and spaceship periods.
  • Automatic scaling for high DPI displays including smartphones and tablets.
  • Editor with unlimitied undo/redo and multiple clipboards.
