Description

This extension adds more expressive alignment requirements for uniform and storage texel buffers. Some implementations have single texel alignment requirements that cannot be expressed via PhysicalDeviceLimits::minTexelBufferOffsetAlignment.

New Structures

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDeviceTexelBufferAlignmentFeaturesEXT

Extending PhysicalDeviceProperties2:
- PhysicalDeviceTexelBufferAlignmentPropertiesEXT

New Enum Constants

EXT_TEXEL_BUFFER_ALIGNMENT_EXTENSION_NAME

Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the EXT suffix omitted. However, only the properties structure is promoted. The feature structure is not promoted and texelBufferAlignment is enabled if when using a Vulkan 1.3 instance. The original type name is still available as an alias of the core functionality.

VkPhysicalDeviceTexelBufferAlignmentFeaturesEXT - Structure describing the texel buffer alignment features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceTexelBufferAlignmentFeaturesEXT 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. PhysicalDeviceTexelBufferAlignmentFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

PhysicalDeviceTexelBufferAlignmentFeaturesEXT
Fields texelBufferAlignment :: Bool `texelBufferAlignment` indicates whether the implementation uses more specific alignment requirements advertised in `PhysicalDeviceTexelBufferAlignmentProperties` rather than `PhysicalDeviceLimits`::`minTexelBufferOffsetAlignment`.
