Falling sand simulation made for testing capabilities of Apus - 2d rendering engine(repo: https://github.com/CodeForBeauty/Apus)
All of the calculations and sand rendering work on CPU using OMP parallelism for speeding up loops.
To only test out program you can get it here: https://github.com/CodeForBeauty/FallingSand/releases/tag/Testing
On launch program expects user to input width and height of a canvas. After inputing width and height app window unfreezes and is free to use or resize.
Pressing left mouse button spawns sand in a circle around cursor. That circle can be resized by pressing [-]/[=] on the keyboard.
Screenshot of a current state of a canvas can be taken by pressing [R] on the keyboard. Screenshot is saved in folder "testing" as "Render.png". Resolution of a taken screenshot is dependent on window size.
ApusCore has become very powerful rendering engine. And is being worked on. More of the similar projects will come in the near future.
