Tips

  • Vertical resolution of 300 gives most realistic results
  • Larger horizontal resolutions allow stronger converging winds to develop, forming more realistic, longer lasting cells
  • Performance is mostly GPU dependent, GTX 1070 or better recommended for realtime gameplay
  • If you have a laptop with a dedicated GPU, make sure the browser is actually using it! It's often using the integrated graphics by default
  • Play in fullscreen mode (F11)
  • Controls

    Mouse

  • Middle mouse button to drag the simulation area around
  • Mouse wheel to zoom in and out, Or to change brush size while holding down B
  • Left mouse button to use selected tool. Hold down Ctrl (command on mac) to perform the inverted action
  • Touchscreen input is pretty basic for now, will add more controls in the future
