So fascinating! Thanks for indirectly leading me to this! I love thinking about all the various approaches available at the pixel/texel/etc level!
It's also another case where it's a very clever way of generating a type of SDF (Signed Distance Field) that is doing a lot of the heavy-lifting. Such a killer result here as well! Any-width-outline-you-like in linear time?!! Amazing when compared to the cost of the brute-force ones at huge widths!
I wholeheartedly endorse SDFs, whether they are 'vector' ones, function-based, like Inigo Quilez's amazing work, Or 'raster' ones like in the article, texel-or-voxel-based. Houdini supports raster-SDFs very well I think, has a solid, mature set of SDF-tools worth checking out (there's a free version if you don't have a lic)!
And of course there's all the many other places SDFs are used!! So useful! Definitely worth raising-awareness of I reckon!
