Visualizing Collision Detection -- Separating Axis Theorem Explained with a Minecraft Datapack

I describe and visualize the Separating Axis Theorem, and how to use it to detect and resolve collisions between oriented boxes.

What's crazy is that I started watching Sethbling when I was very young. Now I'm an engineering student and I can actually understand the math he's talking about now! How time flies.

bro sethblings return has fed my need for these videos

[DonnaPinciot]

Huh, rotated cuboid collision detection is exactly the sort of thing I've been trying to learn recently.
Maybe this will help!

[triq]

i have never encountered this subject in my life but now i feel like i understand it completely, this was very well explained

[Nsta]

Very nice visualization of projections and the Separating Axis Theorem. Well done!

[Poly_]

How cool that the math just works out like that

[josephgoldsborough]

I miss watching sethbling videos i barely comprehend, feels like old times

[NeunEinser]

"Hope you learned something new".

In fact, there was nothing in this video that I already knew, everything was new to me. And it was very nicely explained to, so while I definitely understand the basics of what was said.

Nice video 😊

[cubeoi]

interesting, there's barely any videos on youtube covering collision detection with this so thank you for making this

[Seedx]

Minecraft + physics + math + programming. Love it

[DiggoryJiggory]

Insane how you explained this in an actually understandable manner

[kaihang]

For those of us who began our engineering journey with Redstone, I acknowledge Sethbling as my first professor and Etho as my second.

This 5 minute video just taught me more about 3d physics and collision detection than any of my college game dev courses so far lmfao

SethBling can't be stopped

[henryfleischer]

Nice. I've been getting into game development in the Godot engine, and this has helped me understand why concave collisions don't work as well as convex ones.

[OliBomby]

This is the first time I understand the separating axis theorem. That's so useful!

[poisonshroom]

thank you for incidentally giving me the clearest, most concise definition of cross product i've ever heard

[yeldarb]

Sethbling using advanced calculus and differential equations in redstone. This man has ascended to new levels. From making computers in mc to full physics engines. If mumbo is redstone jesus, sethbling is the redstone god.

[johnsledge]

Wow this was surprisingly easy to understand and really clear.

Well done!! Physics engines are incredibly fascinating.

[gunnararc]

Nice video, good explanation! My master thesis dealt with this problem but for general concave shapes, which makes everything way harder.

This is amazing
I never thought i would see something this complicated in minecraft before today but here we are
