## Name

VkPhysicalDeviceShaderDrawParametersFeatures - Structure describing shader draw parameter features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderDrawParametersFeatures` structure is defined as:

    // Provided by VK_VERSION_1_1
    typedef struct VkPhysicalDeviceShaderDrawParametersFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderDrawParameters;
    } VkPhysicalDeviceShaderDrawParametersFeatures;

    // Provided by VK_VERSION_1_1
    typedef VkPhysicalDeviceShaderDrawParametersFeatures VkPhysicalDeviceShaderDrawParameterFeatures;

## Members

This structure describes the following feature:

## Description

- `sType` is the type of this structure.

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

- `shaderDrawParameters` specifies whether the implementation supports the SPIR-V `DrawParameters` capability. When this feature is not enabled, shader modules must not declare the `SPV_KHR_shader_draw_parameters` extension or the `DrawParameters` capability.

If the `VkPhysicalDeviceShaderDrawParametersFeatures` 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. `VkPhysicalDeviceShaderDrawParametersFeatures` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderDrawParametersFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETERS_FEATURES`
