Writing a Physics Engine from scratch - collision detection optimization

[erinkarp]

The fact that multi-threading made it not deterministic was really interesting

Your original verlet integration video is what got me more interested in C++ & physics simulation, so excited to see this new one come out!

I'll never regret subscribing.

Thanks for the new video! I've not done much related to programming, but collision optimization has been an interest of mine for quite a while. It's great to see such an easy explanation into spacial partitioning.

Great work as always. You're one of the few channels that actually excites me when a new upload appears in my feed.

That has got to be the coolest "thanks for watching" screen I have ever seen

Back when I was growing up, Black and White 2 by Lionsgate was my jam. In the screen before the main menu, a bunch of particles streamed into a box and made the Lionsgate logo.... but you could also mess around with them using your mouse and screw the whole thing up. But if you didn't, it always ended up perfectly. I used to wonder how on earth they managed to implement a physics engine that kept producing the same result over and over, and now almost a decade later you've answered that lingering question. Keep up the amazing work!

I love seeing the grains appear in the crystal lattices that appear. I'd love to see this applied with more physics rules to simulate microstructures to create visual aids for understanding alloys, solid state chemistry, etc.

Amazing video as always!! I love how you show a simple version of the code as a demonstration tool. Very similar to Sebastian Lague, I really hope I could get this good at video making at some point.

Wow. Your videos are so technically impressive! Great job

[thefunbunns]

You always outdo youself on the outro, love your work and knowledge! Thanks for sharing it with all of us!

This is one of your best videos so far man I can tell you spent a lot of time on this and it payed off well

The chicken is now a symbol of success

[glumpfi]

This is so satisfying :)
It would be interestig to see how the chicken picture changed if you re-run the simulation with the exact same settings, except slightly changing the settings of one single object. Like i depiction of the butterfly effect. The more complex the interaction is, the more warping of the chicken should be visible.

I LOVE YOUR VIDEOS!!! Your code is so elegant in so many ways, and your videography is perfect, plus your voice, just everything man, seriously awesome!

[TheBarretNL]

I keep coming back to these video's because they are such good learning subjects, thanks for making them Pezza! you are an absolute legend.

[NaviaryMusic]

Watching the objects construct the image is so satisfying!! I'm sure if you made videos dedicated to showcasing more images being filled, and even made shorts, they would be very successful!

I've been having problems trying to multithread my sim, that idea to use 2 passes is genius! Thank you so much

[weeblewonder]

The visualisations in this video are amazing. They communicate the problem space so effectively. Nice work!

[professionalnerd]

Your physics simulation videos are absolutely mesmerizing... and so educational! I've been following along implementing my own physics engine!
