A pure C implementation of Conway's Game of Life with OpenGL 3 for visuals
- Compact data storage format
- Threadsafe data structure
- Half-step visuals
- CMake 3.13+
- SDL2, SDL2_ttf
- OpenGL (3.3+ core profile), GLEW

Profile mode: Runs a 200x200 world for <i>*1000 iterations. Default
is 1000 iterations.
-i <iterations>
Iterations in profile mode. Multiplied by 1000 for total iterations.
Default is 1 (1000 iterations).
-t
Text mode. Don't start graphical version of world output, only
textual. Prints 5 iterations of the world to stdout. Used primarily
for debugging purposes.
-n <fill_type>
Fill type number. Avaliable options are:
0: Empty
1: Single cell (top left)
2: Even in row (vertical lines)
3: Checkerboard 1 (even)
4: Diagonal lines
5: Odd in row (vertical lines)
6: Checkerboard 2 (odd)
7: Horizontal lines (even)
8: Horizontal lines (odd)
9: Full fill
10: Random fill
This option is useful for initial setup without a pre-existing
world. This option is ignored if a file is specified and exists.
This option applies to profile mode as well as non-profile mode.
-w, -x <width>
Width (horizontal size; x limit) of the world. This option is
ignored if a file is specified and exists.
-h, -y <height>
Height (vertical size; y limit) of the world. This option is ignored
if a file is specified and exists.
-f <filename>
Filename to read world from, and save world to. If reading the file
fails, a default world is created. The world will be saved with this
filename even if initial reading failed.
In graphical mode, these mouse actions are available:
- Left click on cell: Invert cell value
- Mouse scroll: Zoom camera in/out
In graphical mode, these keys are available:
- Q, Esc: Quits the game, saving the world if filename was provided.
- 0-9: Fill with fill type. See CLI options for reference.
- R: Random fill.
- Tab: Show the overlay (basic information).
- V: Toggle vsync.
- N: Iterates the world while pressed.
- M: Iterate world by a single half-step.
- Space: Toggles iterating the world.
- H: Toggles half/full step mode. Half step shows the intermediate step between each full world iteration.
- C: Rotate through available color schemes.
- Shift+C: Reverse rotate through color schemes.
- Ctrl+C: Copy world to clipboard (base64-encoded).
- Ctrl+V: Paste world from clipboard (base64-encoded).
- O: Toggle orthographic vs perspective camera.
- U: Reset camera.
- P: Toggle cell padding (default on).
- X: Save world to filename provided by the
-fparameter. - W,A,S,D,arrow keys: Move camera position relative to world field.
Currently graphical mode is limited to a 1280x720 pixel window.
