Image Resolution For Highest Quality

Nitroman

Hi!
I'm creating some large (approximately 24,000 x 12,000 pixel) equirectangular 360º images for a KRPano virtual tour project.

From what i can see, the auto generated image tiles are normally 512 x 512 pixels.

Is there an optimum original photo resolution that is needed so the KRPano image tiles perfectly divide into these large images and give best quality?

For instance, should the original image be resized and sharpened to 23,040 x 11,520 pixels - so the 512 x 512 tiles divide perfectly into it by 45?

Any thoughts would be much appreciated as i'm hoping users will zoom in to view details.

Thanks in advance.

Hi,

note that depending on the used config setting there can be also a conversion to cube involved.

About 'perfectly divide to tilesize' - that's not necessary, also partial tiles are possible.

But there are some automatic functions here (enabled by default) that tries to find level-sizes that are 'better' dividable, e.g. to avoid tiles that are only a few pixels wide or high and to make them better for GPU/mipmapping rendering:

If you want to get your source pixels as unmodified as possible: disable the cube-conversion and the both settings from above.

Best regards,
Klaus
