wanted to test one thing quickly but no

rustinlee commented 9 years ago

Which iOS? Which device?

makc commented 9 years ago

ipad3 with ios8

mrdoob commented 9 years ago

Any errors?

makc commented 9 years ago

I did not have it connected to mac at the time, so I would not know.

makc commented 9 years ago

By "does not work" I mean it would show me black screen after clicking the thumbnail.

Works on iOS iPads but not on mobile Other WebGL examples from other sites work so it's not WebGL

It displays a black screen.

It probably has something to do with how each example filter is loaded within the same screen (I don't have it connected in debug at the moment)

ncacace commented 6 years ago

Each example's resolution progressively degrades on iPad within minutes. Most probably due to an accumulated error with decimal approximation.

I haven't experienced this with the desktop system

I'm not sure if this is caused by WebGL or just with the glsl-sandbox implimentation http://glslsandbox.com/e#44178.0

mrdoob,

I'm sorry but this was a while ago and there is no reference of the example that wasn't working...

There is no reference to the example that you are generating the screen shot with. Could you include a link to the actual page so that I can check it on my iPad? ...also I'm not even sure that what you are looking at was what I was looking at when I posted my message - so it may not even be Apples and apples.

I've updated my second post with a link and a screenshots but I can't remember which wasn't working - sorry)

mrdoob commented 6 years ago

I've updated my post with a link.

mrdoob commented 6 years ago

Oh, I see your screenshots now. These are probably precision issues with the iPad's GPU. Unfortunately there is nothing we can do about it.

mrdoob commented 6 years ago

Closing this.
