[MacbookPro M1] Crash on 16k displacement map

[ommaury]

Hi Thomas,

On a 14" Macbook Pro M1, I get a crash viewing a 16k map. You can find a map like this here for example:
00_displacement_micro.exr in the following archive:
https://vgl.ict.usc.edu/Data/DigitalEmily2/Data/2.1/Emily_2_1_Textures.zip

The stack trace does highlight a metal texture size limitation (in nanogui):

Hi Olivier, this seems to be a fundamental limitation w.r.t. texture size -- not much to be done by tev / nanogui other than detecting such cases and breaking the rendering down into multiple tiled textures.

This is unlikely to happen soon (if at all), but I'm going to keep the issue open as a "TODO" bullet.

Cheers!

Thanks Thomas for the quick response, makes sense, that's what the native Preview app does it looks like (break the image into 4 tiles).
