VkPipelineCoverageReductionStateCreateInfoNV

The VkPipelineCoverageReductionStateCreateInfoNV structure is defined as:

typedef struct VkPipelineCoverageReductionStateCreateInfoNV {
    VkStructureType sType;
    const void* pNext;
    VkPipelineCoverageReductionStateCreateFlagsNV flags;
    VkCoverageReductionModeNV coverageReductionMode;
} VkPipelineCoverageReductionStateCreateInfoNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• flags is reserved for future use.
• coverageReductionMode is a VkCoverageReductionModeNV value controlling how color sample coverage is generated from pixel coverage.

If this structure is not included in the pNext chain, or if the extension is not enabled, the default coverage reduction mode is inferred as follows:

• If the VK_NV_framebuffer_mixed_samples extension is enabled, then it is as if the coverageReductionMode is VK_COVERAGE_REDUCTION_MODE_MERGE_NV.
• If the VK_AMD_mixed_attachment_samples extension is enabled, then it is as if the coverageReductionMode is VK_COVERAGE_REDUCTION_MODE_TRUNCATE_NV.
• If both VK_NV_framebuffer_mixed_samples and VK_AMD_mixed_attachment_samples are enabled, then the default coverage reduction mode is implementation-dependent.
