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

The members of the PhysicalDeviceFragmentShaderInterlockFeaturesEXT structure describe the following features:

Description

If the PhysicalDeviceFragmentShaderInterlockFeaturesEXT structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. PhysicalDeviceFragmentShaderInterlockFeaturesEXT can also be included in the pNext chain of DeviceCreateInfo to enable features.
