probably requires a powerful machine rather than a phone (I've been testing on a desktop with AMD RX 580 GPU).
some nice settings in the neighbourhood of this one:
added an option for more isotropic mipmap generation - significantly slower but looks much better, so it's enabled by default
techy details: 14-tap separable gaussian blur, sigma 1 pixel, with dimension/2 reduction each direction.
added an option for higher quality texture lookup - significantly slower (again) but looks much better (again) with much less axis-alignment (i.e. still more isotropic (same in all directions))
techy details: does 4 bilinear texture lookups and combines them into a bicubic lookup, code adapted from https://stackoverflow.com/a/42179924 to add level-of-detail support.
made it so the state of the 3 recently added features are saved in the URL hash, so they can be bookmarked and shared properly
here's the settings for the previous toot's images
Response to changes feels similar wild to analog video feedback. It's fun to play with. And an interesting idea!
A friend of mine has loads of analog equipment and we'll be trying to combine his stuff with some shaders. We're a bit slow going, as we need to prep all this stuff and we hadn't much time to meet, but we'll get there eventually.
I'm not asking, just noticing that video in would be a blast for what we're doing.
Awesome! I'll keep you posted if we do something interesting!
fixed the statistics calculations, improved heurstic for randomizing "dead" parameters
improved webcam support
turned the "continuous" toggle into a slider that can vary from discrete at the left edge to continuous on the right edge (it's essentially a global feedback gain control with 1/x mapping)
