Author here. Engineers use clothoids as the primary geometry for high-speed roads by offsetting a centerline clothoid. However, the offset of a clothoid is not itself a clothoid, s…

Nope. But I mean aren't functions of circles essentially some kind of SDFs in 2d? Or at least those of disks.

I will definitely explore this in the future as architecture is probably my next passion after roads :D

This is amazing. Some objective would be great

Author here: i agree the article oversimplified here and in practice vehicle tracks can sometimes be non concentric. But it has nothing to do with differentials. Differentials just…

Will share more soon. I have some more recordings of it on x https://x.com/SandboxSpirit if you're interested.

Thanks for references! I initially considered bevy for this but I was a bit scared it was not mature enough. How do you find it now?

Haha. I myself tried to play CS like that. Start with a historical core. The thing is the way the game is implemented buildings only have rectangular footprints while in reality bu…

True. I mostly meant not personal vehicles, so jut buses, trams etc. I supposed emergency services will use those dedicated lanes. or maybe civilization is so advanced those will b…

Yep, good point. I am myself a huge fan of livable oriented infrastructure (bike lanes, pedestrian paths, public transportation) but the hard truth is that roads were initially des…

I am a huge fan of satisfactory as well (probably no surprise for anyone)

I mean they are not a math nightmare per se if you’re comfortable with the theory. What I meant is that they become comparatively complex to integrate into a system like this. Thin…

Wow, that’s a really detailed deep dive, saved it for a read later. I didn’t even realize clothoids are also tricky to connect. I never really dared to jump into actually implement…

Yes, I don't even know how I didn't know about this at the time of wiring the article. But a must read for sure!

Glad you mentioned it. Cubic parabolas were actually used by eraly railway engineers as good approximations of clothoids back when numerically solving a true euler spiral was a dau…

Very happy reading this because I was always thinking exactly the same about historical games. One of my turn offs for any historical city building is when they are grid based. I a…

For sure I will. Thanks a lot for your interest. To anybody's disappointment, I didn't even know Hacker News was a thing until I saw a ton of traffic coming from it. But I guess I'…

Hello, I am the creator of this road system. The thing is that I myself don't even know what I want to do with it. lol. Maybe an asset or a game (a bit scared to jump in a full fle…
