 # C++ Particle Sim
+
+This is still very much a work not really in progress!
+
+## TODO
+- [x] Particle collisions with the walls
+- [] Particle gravities
+- [] Particle collision with other particles
+- [] Maybe add a 3rd dimension?
+
+## Building and Running
+
+You're on your own with figuring out how to install cuda...but in theory once that's installed it should be pretty straight forward:
+```
+cmake -S ./ -B build/
+cmake --build build/
+cd build/
+./src/particle_sim_exe
+```
+
+Current system runs 10,000 particles at 50fps. The gif below only appears to be moving slow because the time steps between renders is much lower then in the python example. The frame is actually higher here then it was in python.

 This script will generate 100 particles to be used in the simulation and renders at about 20fps.
