Description

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

This extension may be useful to restrict a ImageView 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.

Synopsis

data PhysicalDeviceImageViewMinLodFeaturesEXT Source #

VkPhysicalDeviceImageViewMinLodFeaturesEXT - Structure describing whether clamping the min lod of a image view is supported by the implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceImageViewMinLodFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceImageViewMinLodFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

VkImageViewMinLodCreateInfoEXT - Structure describing the minimum lod of an image view

Description

If the pNext chain includes a ImageViewMinLodCreateInfoEXT structure, then that structure includes a parameter specifying a value to clamp the minimum LOD value during Image Level(s) Selection, Texel Gathering and Integer Texel Coordinate Operations.

If the image view contains ImageViewMinLodCreateInfoEXT and it is used as part of a sampling operation:

minLodFloatimageView = minLod

otherwise:

minLodFloatimageView = 0.0

An integer variant of this parameter is also defined for sampling operations which access integer mipmap levels:

minLodIntegerimageView = ⌊minLodFloatimageView⌋

Valid Usage

  • If the minLod feature is not enabled, minLod must be 0.0
  • minLod must be less or equal to the index of the last mipmap level accessible to the view

Valid Usage (Implicit)
