Show HN: WebGL-powered oscilloscope emulator
- jkleiser 11y agoI like it, but I would prefer a plain oscilloscope function, and being able to connect it to a Web Audio source of mine.
- m1el 11y agoMaybe I'll try doing that this weekend.

- Udo 11y agoAre you on Firefox by chance? I discovered this week that Firefox doesn't do ES6 on included <script> files unless you specify an explicit content type enabling it (which in turn breaks things on all other browsers).
- virgil_disgr4ce 11y agoNice, I assume this is XY-mode by stereo channel. I did a little writeup here: http://cookingwithsound.com/an-xy-mode-oscilloscope-in-your-browser/ http://cookingwithsound.com/an-xy-mode-oscilloscope-in-your-... If you want to get in touch, I'd love to add more detail about how the code works :)
- m1el 11y agoI am planning to do a writeup on the core algorithm myself. But in a few words: linear algebra and integrals. *Edit
- hughes 11y agoThat was one of the highest-fidelity visual experiences I've had on the web. I know there's no more information being displayed than what's in the audio channel, but I feel like this sort of experience just wouldn't translate well to any current video encoding, even at enormous file sizes. Thanks for building this and for sharing!
- m1el 11y agoYou're very welcome.
- leetbulb 11y agokhrậng. amazing.
- phkahler 11y agoThat could be an awesome previewer for .ild files (Laser Show stuff). The OpenLase and VectorBoy projects might like to hear from you. It would may also be really nice for rendering the old vector games in MAME - I have a Cinematronics emulator that can run about 13 vector games too, mostly black and white.
