Recreating Noita's Falling Sand Simulation | Game Engineering - EP01

https://www.youtube.com/watch?v=VLZjd_Y1gJ8

Inspired by Noita, this is a simple "falling sand" simulation to demonstrate the mechanics and ideas behind Cellular Automata.

Building

NOTE(john): Currently requires at least OpenGL v3.3 to run. This will be addressed in the future to allow for previous opengl versions.

• windows:
  • You'll need to have Visual Studio 2015 or greater.
  • From start menu, search for "x64 Native Tool Command Prompt for {Insert your Version Here}"
  • Navigate to where you have EP01_SandSim repo placed
  • run proc\win\compile_win_cl.bat
  • The executable will be placed in bin\
  • run bin\SandSim.exe
• mac:
  • You'll need gcc
  • From the terminal, cdinto the root directory for this project.
  • run bash ./proc/osx/compile_osx_gcc.sh
  • The exectuable will be placed in bin/
  • run ./bin/SandSim
• linux:
  • You'll need gcc
  • From the terminal, cd into the root directory for this project.
  • run bash ./proc/linux/compile_linux_gcc.sh
  • The exectuable will be placed in bin/
  • run ./bin/SandSim

Controls

• [: Decrease paint tool radius
• ]: Increase paint tool radius
• c: Clear canvas of all particles
• i: Enable/Disable all UI
• p: Pause simulation
• b: Enable/Disable post-processing
• esc: Quit application
• Left click mouse to paint particles into scene
• Right click mouse to erase particles from scene
• The user can drag & drop images into the program. Any .png, .jpeg/.jpg images will work.
