Stereographic projection

[Tipen]

I’m really late, but this is just so simple but so elegant. Also it looks awesome, and I can actually see there being decent application for it

[iamayin]

can't wait for this to get recommended to everybody

[elmostos]

This is cool, illustrates one reason why flat maps distort the globe; shapes that on the sculpture are obviously different sizes appear as equal squares when projected

[McArRuIzO]

Fun theory (not fact lol): Some scientists believe in physics similar to this that prove the entire universe itself is a sphere, like planets are. Most physicists consider the "fabric of space" to be a plane. But they feel its planar nature is a projection of sorts, one similar to this. It's far too complex to really explain in a comment, and I can't say I know all the theoretical physics behind it anyway.

This is really cool! What software/instruments did you use to make the sculptures?

[Kram]

neat! How about a version which actually has space for a single LED in the exact right position?

New thing: Stereographic projection. Using light rays to map from the sphere to the plane.

This could also be an excellent model to demonstrate Mercator projection in mapmaking. The two lines that are tangent to the plane would be analogous to the equator and prime meridian.

Properly explaining something like this in 1 minute is a talent! Well done 👏

Hey Henry, loving your 3D prints and your designs... and this vid is 9 years old! How I wish I'd found your channel earlier 🥲

[xanderlewis]

I love how I can open up my computer, type in 'stereographic projection', and immediately get back something like this that illustrates it beautifully (in two dimensions, anyway).

[serse]

As a topology tutor, I want a 3d printer so bad.
This would make for a cool demonstration

[rqndxm]

Here before this blows up in everyone's recommended videos!

[zzzzs]

these would be cool to use as lights in public places like car parks and stuff like that

[AdamStallard]

Thank you. That helped me visualize SPs in my noggin much better.

[Canale]

See you in 5 years when the algorithm recommends this to everyone

[LunaMapping_KR]

Simple yet elegant, very cool, to the point

[CRlMZlN]

You've been blessed by the algorithm.

[shonenbag]

I thought that was CG for a second! That's awesome!
