Description
This extension adds support for the FragmentShaderPixelInterlockEXT,
FragmentShaderSampleInterlockEXT, and
FragmentShaderShadingRateInterlockEXT capabilities from the
SPV_EXT_fragment_shader_interlock extension to Vulkan.
Enabling these capabilities provides a critical section for fragment shaders to avoid overlapping pixels being processed at the same time, and certain guarantees about the ordering of fragment shader invocations of fragments of overlapping pixels.
This extension can be useful for algorithms that need to access per-pixel data structures via shader loads and stores. Algorithms using this extension can access per-pixel data structures in critical sections without other invocations accessing the same per-pixel data. Additionally, the ordering guarantees are useful for cases where the API ordering of fragments is meaningful. For example, applications may be able to execute programmable blending operations in the fragment shader, where the destination buffer is read via image loads and the final value is written via image stores.

data PhysicalDeviceFragmentShaderInterlockFeaturesEXT Source #
VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT - Structure describing fragment shader interlock features that can be supported by an implementation
Members
This structure describes the following features:
Description
If the PhysicalDeviceFragmentShaderInterlockFeaturesEXT 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. If the application wishes to use a
Device with any features described by
PhysicalDeviceFragmentShaderInterlockFeaturesEXT, it must add an
instance of the structure, with the desired feature members set to
TRUE, to the pNext chain of
DeviceCreateInfo when creating the
Device.
