SFML and CMake need to be installed.
Create a build directory
mkdir build
cd buildConfigure and build the project
cmake ..
cmake --build .On Windows it will build in debug by default. To build in release you need to use this command
cmake --build . --config ReleaseYou will also need to add the res directory and the SFML dlls in the Release or Debug directory for the executable to run.
If he could display the image I specified, it would be very cool.
Been working on something similar and noticed that circles tend to stay in collision if not interesting sufficiently many times. I saw that in your implementation, you only iterate two times, not until convergence, correct?
However, the results seem to show pretty much perfect collision resolution, which doesn't make any sense to me. Is there any intuitive explanation?

and

I'm assuming the breakable bricks in the intro to your video are just multiple circle particles attached to eachother? Can you share some insight as to how you implemented this?
I was wondering if it would be possible to start the simulation with a given starting condition.
For instance, I want to see if I can simulate a galaxy colliding with another with this engine.
Is this possible with this repository?
I get these build errors.

Any ideas? I'm pretty sure I'm building correctly. I make a build folder in the main directory and then enter it. Then I do
cmake .. and cmake --build .. Thanks!
Edit: I'm on Fedora Linux. I have installed SFML and SFML-devel. Also CMake is installed.
Looking at this line in physics_object.hpp:
const Vec2 new_position = position + last_update_move + (acceleration - last_update_move * 40.0f) * (dt * dt);How would I have the particles display an image as shown in the video?
So, this lags pretty badly on my computer when you make the world size much larger than 300x300, no matter how many particles there are. I think this is just because of the sheer number of cells it needs to loop through.
So i'm wondering, is there any reason you loop through every single cell? Seems super unnecessary, why not just loop through all the cells with particles in them? The way I would implement this is by having a vector in the PhysicsSolver class, to store all the cells with particles in them. This vector would get cleared at the beginning of each loop, and then in the method to add the particles to the grid, you could just push the index of the current particle in the grid to the back of this vector.
I guess there may be some issues with threading, but my approach is to 'pad' the vector of active cells until it's a multiple of the thread count.
So, is there any issue with doing this?
