Fun and informative, a great combination!
prox on HNThis is really awesome!
chrisbennet on HNLooks very cool!
Karmic_Clash on HNDiego, this is really amazing. The one gif where you throw a block into a stack reminds of some interesting property of the laws of classical mechanics: they are reversible. That…

Does not compile without Qt pre-installed; missing libs or headers
From 1 comment
Does the Visual Studio project require QT be pre-installed? I don't see libs or headers in the dependencies, and I don't have QT on my dev system. So the project does not compile.

Application to UI scrolling behavior via headless simulation
From 1 comment
There might be a really useful related application here. If I could set up a 2D scene to be simulated headlessly, apply forces programmatically, and then receive the x position…

Can the simulation be deterministically reversible?

Diego, this is really amazing. The one gif where you throw a block into a stack reminds of some interesting property of the laws of classical mechanics: they are reversible. That…

Is extrapolation with a fixed timestep possible?
From 1 comment
This is great! One very naive (I'm trying to learn) question: You have a fixed timestep for good reason, which works great if you're displaying by doing interpolation (your…

Pyslvs-UI and pyslvs (SolveSpace-based solver)
From 1 comment
Nice. FTR, Also Pyslvs-UI may be useful for 2D kinematics analyze and you also could use its core ("pyslvs"; and based on SolveSpace[2] solver) module written in Python. [0]…
