How do Computers Translate 3D Worlds Into Pixels?

By Jamie Condliffe on at

Computers love to think in triangles to create 3D representations of the real world—but how do you represent those intelligently constructed objects as flat 2D shapes on a screen? This video describes exactly how 3D models are turned into pixels.

It's not actually the most straightforward process, leaping from a simulated 3D world to a flat pixelated one. In fact, the solution requires some common sense and a dollop of math—but the results are hugely important. [Computerphile]
