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 maths — but the results are hugely important. [Computerphile]
