I really enjoyed this. How it explains why you van turn a sphere inside out, but not a circle.

wouldn't you be able to turn a sphere inside out because it's 3D, and not a circle because it's 2D? seems like an easier explanation to me.

Mathematicians have far too much time on their hands.

That's not an explanation.

That chick has a hot voice.

Also, I just pulled a rubber band inside out wrongly to spite the video.

I wonder how much money was wasted on this.

There wasn't a rubber band in the video.

Finding simple methods to solve complex problems mathematically isn't a waste of money.

Quoting Speedfreak: There wasn't a rubber band in the video.



I know, it's all I had on-hand that was close to the circle they used in the video lol.

Shame there's no material in known existance that can pass through itself!




Posted by Speedfreak

There was no known applicable use for mathematically displaying 2D images with pixels, 3D models with polygons or various textured surface simulations with bump mapping at the time the theories for those techniques were devised. Yet decades later they're all used in real time for things as trivial as video games.

The point of this theory isn't in case we discover a material that passes through itself, it's for transforming curves according to certain rules. Those rules probably have something to do with how computers freak out when infinity is involved, such as in the infinitely sharp corners in the video. Did anyone actually listen to the video?

yea im not going to watch all 21 minutes of that, i got to where she said you cant turn a circle inside out then turned it off

It takes 21 minutes to turn a sphere inside out? THE MORE YOU KNOW

The animator must have had alot of fun making that.
