}
(Hint: it’s not an error, but it is a warning.)

In this article I’m going to present a technique that trades lower image quality for faster rendering time: interpolation.
Instead of ray-tracing every single pixel, we instead start by tracing pixels in an evenly-spaced grid, say every two or four pixels. (So if we have an interpolation step of two, we trace one out of every [...]
