Description

This extension allows applications to clamp the minimum LOD value during Image Level(s) Selection and Integer Texel Coordinate Operations with a given VkImageView by VkImageViewMinLodCreateInfoEXT::minLod.

This extension may be useful to restrict a VkImageView to only mips which have been uploaded, and the use of fractional minLod can be useful for smoothly introducing new mip levels when using linear mipmap filtering.
