C Specification

If the pNext chain of VkSubpassDescription2 or VkRenderingInfo includes a VkMultisampledRenderToSingleSampledInfoEXT structure, then that structure describes how multisampled rendering is performed on single sampled attachments in that subpass.

The VkMultisampledRenderToSingleSampledInfoEXT structure is defined as:

// Provided by VK_EXT_multisampled_render_to_single_sampled
typedef struct VkMultisampledRenderToSingleSampledInfoEXT {
    VkStructureType          sType;
    const void*              pNext;
    VkBool32                 multisampledRenderToSingleSampledEnable;
    VkSampleCountFlagBits    rasterizationSamples;
} VkMultisampledRenderToSingleSampledInfoEXT;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • multisampledRenderToSingleSampledEnable controls whether multisampled rendering to single-sampled attachments is performed as described below.

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

Description

Valid Usage
  • VUID-VkMultisampledRenderToSingleSampledInfoEXT-rasterizationSamples-06878
    The value of rasterizationSamples must not be VK_SAMPLE_COUNT_1_BIT

  • VUID-VkMultisampledRenderToSingleSampledInfoEXT-pNext-06879
    If added to the pNext chain of VkSubpassDescription2, each render pass attachment in VkRenderPassCreateInfo2::pAttachments that is referenced by this subpass must have a format that supports the sample count specified in rasterizationSamples

  • VUID-VkMultisampledRenderToSingleSampledInfoEXT-pNext-06880
    If added to the pNext chain of VkRenderingInfo, each imageView member of any element of VkRenderingInfo::pColorAttachments, VkRenderingInfo::pDepthAttachment, or VkRenderingInfo::pStencilAttachment that is not VK_NULL_HANDLE must have a format that supports the sample count specified in rasterizationSamples

Valid Usage (Implicit)
  • VUID-VkMultisampledRenderToSingleSampledInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_MULTISAMPLED_RENDER_TO_SINGLE_SAMPLED_INFO_EXT

  • VUID-VkMultisampledRenderToSingleSampledInfoEXT-rasterizationSamples-parameter
    rasterizationSamples must be a valid VkSampleCountFlagBits value
