public final class EXTShaderDemoteToHelperInvocation extends java.lang.Object
This extension adds Vulkan support for theSPV_EXT_demote_to_helper_invocation
SPIR-V extension. That SPIR-V extension provides a new instructionOpDemoteToHelperInvocationEXT
allowing shaders to "demote" a fragment shader invocation to behave like a helper invocation for its duration. The demoted invocation will have no further side effects and will not output to the framebuffer, but remains active and can participate in computing derivatives and in subgroup operations. This is a better match for the "discard" instruction in HLSL.Examples
None.
