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.

Documentation
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.

data ImageViewMinLodCreateInfoEXT Source #
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,
minLodmust be0.0
Valid Usage (Implicit)
-
sTypemust beSTRUCTURE_TYPE_IMAGE_VIEW_MIN_LOD_CREATE_INFO_EXT
