Hi,

the reason therefore is 'mip-mapping'.

With mip-mapping WebGL will automatically use down-scaled versions of the image for smaller renderings. This avoids aliasing. But there is a limitation - only images (tiles) that have a 'power-of-two' size like 512(=2^9), 1024(=2^10), 2048(=2^11) can be mip-mapped.

In IE11 there is no visual change because the IE11 WebGL implementation doesn't fully support mip-mapping.

See also here:
http://krpano.com/docu/xml/#display.mipmapping

In krpano version 1.17.pr2 currently only the mipmapping settings 'auto' and 'none' are implemented. The setting 'force', which will internally enlarge the tile image to fit into the next available 'power-of-two' size, will come with future versions.

To have an uniform rendering you could disable mip-mapping at all - e.g. with:


Here your example with that settings:

Hi,

yes, if you want to take advantage of the mip-mapping, try to size the levels to be dividable into power-of-two tile-sizes (e.g. partials tiles like 128x512 or 64x512 are also working).

Btw - I'm already planing also an option for letting the krpano tools do that automatically.

Best regards,
Klaus
