claudeWorking on 'et' (my escape-time <a href="https://post.lurk.org/tags/fractal" class="mention hashtag" rel="nofollow noopener" target="_blank">#fractal</a> program) this morning.I added <a href="https://post.lurk.org/tags/supersampling" class="mention hashtag" rel="nofollow noopener" target="_blank">#supersampling</a> presets from 1x1 through 8x8, selectable by keypress. It already did supersampling but you had to enter 3 numbers in a modal dialog.The calculations of the array used for progressive image rendering were annoyingly slow, so I'm now caching them on disk using the xdg-basedir and vector-mmap packages (et is written in <a href="https://post.lurk.org/tags/haskell" class="mention hashtag" rel="nofollow noopener" target="_blank">#Haskell</a>). I also need the directory and filepath packages for this part.The arrays get quite big, almost 700MB total for all supersampling sizes with a base resolution of 1024x576 pixels (it takes up 6 bytes per pixel). Changing the base resolution size means recalculating and storing another set of arrays. Cache will bloat!So I'm thinking there might be a better procedural way to do what the arrays do, which is <a href="https://post.lurk.org/tags/adam7" class="mention hashtag" rel="nofollow noopener" target="_blank">#Adam7</a> style interlacing (coarse pixels getting gradually finer in a multipass rendering) with the pixels in each pass ordered so that the center gets rendered first and it spreads out towards the edges.So in short I need a cheap function from (ImageWidth, ImageHeight, PixelIndex) to (PixelX, PixelY, PixelWidth, PixelHeight), because using anything other than <a href="https://post.lurk.org/tags/atomics" class="mention hashtag" rel="nofollow noopener" target="_blank">#atomics</a> to increment PixelIndex is much too slow in <a href="https://post.lurk.org/tags/concurrent" class="mention hashtag" rel="nofollow noopener" target="_blank">#concurrent</a> <a href="https://post.lurk.org/tags/multicore" class="mention hashtag" rel="nofollow noopener" target="_blank">#multicore</a> Haskell.
