Derivatives will be computed via differencing -- over a 2x2 group of shader invocations. The @DerivativeGroupQuadsNV@ -- execution mode assembles shader invocations into 2x2 groups, where each -- group has x and y coordinates of the local invocation ID of the form -- (2m+{0,1}, 2n+{0,1}). The @DerivativeGroupLinearNV@ execution mode -- assembles shader invocations into 2x2 groups, where each group has local -- invocation index values of the form 4m+{0,1,2,3}. -- -- == New Structures -- -- - Extending -- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2', -- 'Vulkan.Core10.Device.DeviceCreateInfo': -- -- - 'PhysicalDeviceComputeShaderDerivativesFeaturesNV' -- -- == New Enum Constants -- -- - 'NV_COMPUTE_SHADER_DERIVATIVES_EXTENSION_NAME' -- -- - 'NV_COMPUTE_SHADER_DERIVATIVES_SPEC_VERSION' -- -- - Extending 'Vulkan.Core10.Enums.StructureType.StructureType': -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_COMPUTE_SHADER_DERIVATIVES_FEATURES_NV' -- -- == New SPIR-V Capability -- -- - -- -- - -- -- == Issues -- -- (1) Should we specify that the groups of four shader invocations used -- for derivatives in a compute shader are the same groups of four -- invocations that form a “quad” in shader subgroups? -- -- __RESOLVED__: Yes. -- -- == Examples -- -- None. -- -- == Version History -- -- - Revision 1, 2018-07-19 (Pat Brown) -- -- - Initial draft -- -- == See Also -- -- 'PhysicalDeviceComputeShaderDerivativesFeaturesNV' -- -- == Document Notes -- -- For more information, see the -- -- -- This page is a generated document.
