  I see two errors in the console. The first: ReferenceError: genDataFromText is not defined This is because genDataFromText is defined inline in the main page after shaderoo.js loads. Edit: now that I think about it, just because shaderoo.js is loaded first, doesn't mean getDataFromText will by called immediately. I don't have the time to debug or even just read someone else's code right now, so I'll just leave it at that. The second: NotAllowedError: The play method is not allowed by the user agent or the platform in the current context, possibly because the user denied permission. Alas Firefox is failing to tell me where exactly in the code the error is coming from. I also see this warning: Loading failed for the <script> with source “http://127.0.0.1:8081/socket.io/socket.io.js?_=1585039727308”. That's true, I'm not hosting anything on http://127.0.0.1:8081 http://127.0.0.1:8081 :eyeroll:

    oh, thanks for the comprising debug info... yes, the first error might not be crucial... i think i tracked down the reason, its due to some new code-inline-image feature i'm currently testing. some lines too long in the shader code - firefox doesn't seem to like that... i'm on it... and the socket stuff is for remote osc-connections (you'd have to start a small server-script locally to use that - see shaderoo help-page)

    ok, the page should load now on firefox. (but my new inline-images still not working there ...i'll dive into it)

  #metoo other examples seem to work e.g.: https://www.shaderoo.org/?shader=A3X0e7 https://www.shaderoo.org/?shader=A3X0e7

This is something I've started trying to implement w marching cubes, but looking at what you're doing, tetras makes a lot more sense! Curious why there are tetrahedral artifacts? I'd have thought marching tetras should yield roughly the same tessellation as mcubes? Also, I couldn't find the Geom->.OBJ button! Super cool stuff!!

problems with hanging on firefox should be fixed now. tell me if you still have trouble on other platforms/OS/etc.

Why is it trying to load a script from 127.0.0.1 ?
- flockaroo 7y ago
  its trying to communicate to an (optionally started) osc-bridge-script. (you can download this at shaderoo.org (see help section) and start it manually on your localhost to be able to communicate to an OSC-device to adjust parameters - e.g for VJ'ing)
