Band-Limiting Procedural Textures
This is awesome! This reminds me of MinBLEP audio synthesis of discontinuous functions (<a href="https://www.cs.cmu.edu/~eli/papers/icmc01-hardsync.pdf" rel="nofollow">https://www.cs.cmu.edu/~eli/papers/icmc01-hardsync.pdf</a>). Instead of doing things at high sampling rate and explicitly filtering, generate the band-limited version directly.<p>In the article, talking about smoothstep approximation of sinc: "I'd argue the smoothstep version looks better" Why would this be? I would have thought the theoretically correct sinc version would look nicer.
