The Leading Edge: Seeing our 3D World in Points and Lines
The world of 3D visualization is more than just action movies. It allows the machines around us to create 3-dimensional representations of their surroundings. Machines are using the points and lines of geometry in car factories, gymnastics stadiums, rocket testing, and elsewhere to accurately recognize the shapes and positions of objects. In this episode, we'll look at the technologies and geometries that allow machines to see in 3D. And we'll meet a man who's created some of the sharpest blades imaginable.
