C Specification

The VkPipelineMultisampleStateCreateInfo structure is defined as:

typedef struct VkPipelineMultisampleStateCreateInfo {
    VkStructureType                          sType;
    const void*                              pNext;
    VkPipelineMultisampleStateCreateFlags    flags;
    VkSampleCountFlagBits                    rasterizationSamples;
    VkBool32                                 sampleShadingEnable;
    float                                    minSampleShading;
    const VkSampleMask*                      pSampleMask;
    VkBool32                                 alphaToCoverageEnable;
    VkBool32                                 alphaToOneEnable;
} VkPipelineMultisampleStateCreateInfo;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • flags is reserved for future use.

  • rasterizationSamples is a VkSampleCountFlagBits specifying the number of samples per pixel used in rasterization.

  • sampleShadingEnable can be used to enable Sample Shading.

  • minSampleShading specifies a minimum fraction of sample shading if sampleShadingEnable is set to VK_TRUE.

  • pSampleMask is a bitmask of static coverage information that is ANDed with the coverage information generated during rasterization, as described in Sample Mask.

  • alphaToCoverageEnable controls whether a temporary coverage value is generated based on the alpha component of the fragment’s first color output as specified in the Multisample Coverage section.

  • alphaToOneEnable controls whether the alpha component of the fragment’s first color output is replaced with one as described in Multisample Coverage.

Description

Valid Usage
  • If the sample rate shading feature is not enabled, sampleShadingEnable must be VK_FALSE

  • If the alpha to one feature is not enabled, alphaToOneEnable must be VK_FALSE

  • minSampleShading must be in the range [0,1]

  • If the subpass has any color attachments and rasterizationSamples is greater than the number of color samples, then sampleShadingEnable must be VK_FALSE

Valid Usage (Implicit)
