According to Einstein’s theory of special relativity, space and time are not absolute, and objects become shorter when moving at larger velocities. So what happens if you take a photo of an object moving at, say, 90% of the speed of light? To answer this question, I’ll start with a normal ray-tracer used to render 2D views of 3D scenes, discuss the consequences of special relativity for moving objects, and then modify the ray-tracer to be consistent with special relativity. Even if you already know about special relativity, the answer might still be surprising.
