Hello, it looks like aliasing by default. It will be better after zooming in. How can I deal with this?

There's no antialiasing, since WebGL 1 only supports mipmapping for power-of-two images.

Safari added support for WebGL 2 more than two years ago at this point, and was the last major browser to do so, so I should revisit switching to WebGL 2 and enabling mipmapping at some point.

How can I deal with this?

Aliasing is less of an issue if you use Pannellum's multires format, since its tiles are scaled less.

OK, thanks
