public final class EXTFragmentShaderInterlock extends java.lang.Object
This extension adds support for theFragmentShaderPixelInterlockEXT
,FragmentShaderSampleInterlockEXT
, andFragmentShaderShadingRateInterlockEXT
capabilities from theSPV_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.
