## Name

VkPipelineRepresentativeFragmentTestStateCreateInfoNV - Structure specifying representative fragment test

Loading… please wait.

## C Specification

If the `pNext` chain of VkGraphicsPipelineCreateInfo includes a `VkPipelineRepresentativeFragmentTestStateCreateInfoNV` structure, then that structure includes parameters controlling the representative fragment test.

The `VkPipelineRepresentativeFragmentTestStateCreateInfoNV` structure is defined as:

    // Provided by VK_NV_representative_fragment_test
    typedef struct VkPipelineRepresentativeFragmentTestStateCreateInfoNV {
        VkStructureType    sType;
        const void*        pNext;
        VkBool32           representativeFragmentTestEnable;
    } VkPipelineRepresentativeFragmentTestStateCreateInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

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

- `representativeFragmentTestEnable` controls whether the representative fragment test is enabled.

## Description

If this structure is not included in the `pNext` chain, `representativeFragmentTestEnable` is considered to be `VK_FALSE`, and the representative fragment test is disabled.

If the active fragment shader does not specify the `EarlyFragmentTests` execution mode, the representative fragment shader test has no effect, even if enabled.

Valid Usage (Implicit)

- VUID-VkPipelineRepresentativeFragmentTestStateCreateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_REPRESENTATIVE_FRAGMENT_TEST_STATE_CREATE_INFO_NV`
