Glitches on Mobile #3
Comments
Woah, this runs on mobile?!? Firstly I'm amazed and curious what you're running it on and how you got it on there? I wrote this for desktop and developed it on Windows 7/8.1 with Visual Studio so not really surprised it's not running. Are you using the master branch as a base? It needs texture lookup in the vertex shader to do the displacement. According a post on StackOverflow that might be a problem as your hardware may not have it implemented. Let me know, maybe we can work around it. |
Hmm, that does look like a precision problem. The noise library I use is, with only a few additions or changes, just the one from Ashima so you might have better luck there or by asking on StackOverflow if that's the only part you're using. |
When running on an ES 2.0 mobile device there are visual artifacts that are not present on the desktop version. I thought this could be a precision problem, but changing to 'highp' didn't seem to work. Could this be the actual math operations on the GPUs? Or the compiler maybe? Completely stumped.
