Idea originally from here. Oh – and please, please, please – don’t even think about using this as an [...]
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 [...]
