Күн бұрын

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.

@meowjustme6865 Ай бұрын

How do you feel now that you understand the math?

bro sethblings return has fed my need for these videos

@Cuestrupaster Ай бұрын

If you want more videos that are kinda like this I recommend WhiteStoneJazz specially his video about why mobs tend to go up and the pattern series.

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

@codinghuman9954 Ай бұрын

I have and this is the best explanation ive seen

@DonnaPinciot Ай бұрын

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

@Nsta1 Ай бұрын

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

How cool that the math just works out like that

@zackbuildit88 Ай бұрын

That's what makes it math :]

@boltstrikes429 Ай бұрын

You're encouraged to dig into it and find out *why* it works out like that :D

Ikr. Man this guy is singlehandedly responsible for me getting into IT

@cubeoi Ай бұрын

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

@NeunEinser Ай бұрын

"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 😊

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

@henryfleischer404 Ай бұрын

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.

Wow this was surprisingly easy to understand and really clear. Well done!! Physics engines are incredibly fascinating.

@yeldarb300 Ай бұрын

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.

Neat! I've only ever learned about aligned axis cuboids, general squares, and fully general 3D (convex but you can stitch multiple together for concave) shapes (via GJK - Gilbert-Johnson-Keerthi algorithm)

@adlsfreund Ай бұрын

Really well explained. I was surprised that the 15 axes can also give the smallest possible movement to separate the cubes.

For those curious, this theorem generalizes to any n-dimensional euclidean space, where if two convex subsets are disjoint, there exists an (n-1)-dimensional hyperplane separating them

@nielsbishere Ай бұрын

wow I had no idea it was that easy once you lay it out like that. Just 2x 3x2 plane projections for the face -> corners and 2x 3x3 for the edge collisions. The dot is then the distance.
