C Specification

The VkMicromapVersionInfoEXT structure is defined as:

// Provided by VK_EXT_opacity_micromap
typedef struct VkMicromapVersionInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    const uint8_t*     pVersionData;
} VkMicromapVersionInfoEXT;


  • sType is the type of this structure.

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

  • pVersionData is a pointer to the version header of a micromap as defined in vkCmdCopyMicromapToMemoryEXT



pVersionData is a pointer to an array of 2×VK_UUID_SIZE uint8_t values instead of two VK_UUID_SIZE arrays as the expected use case for this member is to be pointed at the header of a previously serialized micromap (via vkCmdCopyMicromapToMemoryEXT or vkCopyMicromapToMemoryEXT) that is loaded in memory. Using arrays would necessitate extra memory copies of the UUIDs.

Valid Usage (Implicit)
  • VUID-VkMicromapVersionInfoEXT-sType-sType

  • VUID-VkMicromapVersionInfoEXT-pNext-pNext
    pNext must be NULL

  • VUID-VkMicromapVersionInfoEXT-pVersionData-parameter
    pVersionData must be a valid pointer to an array of uint8_t values
