# VkPhysicalDeviceComputeShaderDerivativesFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceComputeShaderDerivativesFeaturesNV - Structure describing compute shader derivative features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceComputeShaderDerivativesFeaturesNV` structure is defined as:

    // Provided by VK_NV_compute_shader_derivatives
    typedef struct VkPhysicalDeviceComputeShaderDerivativesFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           computeDerivativeGroupQuads;
        VkBool32           computeDerivativeGroupLinear;
    } VkPhysicalDeviceComputeShaderDerivativesFeaturesNV;

## Members

This structure describes the following features:

## Description

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `computeDerivativeGroupQuads` indicates that the implementation supports the `ComputeDerivativeGroupQuadsNV` SPIR-V capability.

- `computeDerivativeGroupLinear` indicates that the implementation supports the `ComputeDerivativeGroupLinearNV` SPIR-V capability.

See Quad shader scope for more information.

If the `VkPhysicalDeviceComputeShaderDerivativesFeaturesNVfeatures`. structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceComputeShaderDerivativesFeaturesNVfeatures`. can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceComputeShaderDerivativesFeaturesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COMPUTE_SHADER_DERIVATIVES_FEATURES_NV`
