Description

This extension allows applications to clamp the minimum LOD value during Image Level(s) Selection 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.

New Structures

Extending ImageViewCreateInfo:
- ImageViewMinLodCreateInfoEXT

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDeviceImageViewMinLodFeaturesEXT

New Enum Constants

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 features:

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

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)

sType must be STRUCTURE_TYPE_IMAGE_VIEW_MIN_LOD_CREATE_INFO_EXT

PhysicalDeviceImageViewMinLodFeaturesEXT
Fields minLod :: Bool `minLod` indicates whether the implementation supports clamping the minimum LOD value during Image Level(s) Selection and Integer Texel Coordinate Operations with a given `ImageView` by `ImageViewMinLodCreateInfoEXT`::`minLod`.

ImageViewMinLodCreateInfoEXT
Fields minLod :: Float `minLod` is the value to clamp the minimum LOD accessible by this `ImageView`.
