Description

This extension adds Vulkan support for the SPV_KHR_terminate_invocation SPIR-V extension. That SPIR-V extension provides a new instruction, OpTerminateInvocation, which causes a shader invocation to immediately terminate and sets the coverage of shaded samples to 0; only previously executed instructions will have observable effects. The OpTerminateInvocation instruction, along with the OpDemoteToHelperInvocation instruction from the VK_EXT_shader_demote_to_helper_invocation extension, together replace the OpKill instruction, which could behave like either of these instructions. OpTerminateInvocation provides the behavior required by the GLSL discard statement, and should be used when available by GLSL compilers and applications that need the GLSL discard behavior.

data PhysicalDeviceShaderTerminateInvocationFeaturesKHR Source #

VkPhysicalDeviceShaderTerminateInvocationFeaturesKHR - Structure describing support for the SPIR-V SPV_KHR_terminate_invocation extension

Members

The members of the PhysicalDeviceShaderTerminateInvocationFeaturesKHR structure describe the following feature:

Description

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