VkCopyMicromapModeEXT

Micromap copy mode

Possible values of mode specifying additional operations to perform during the copy, are:

typedef enum VkCopyMicromapModeEXT {
    VK_COPY_MICROMAP_MODE_CLONE_EXT = 0,
    VK_COPY_MICROMAP_MODE_SERIALIZE_EXT = 1,
    VK_COPY_MICROMAP_MODE_DESERIALIZE_EXT = 2,
    VK_COPY_MICROMAP_MODE_COMPACT_EXT = 3,
} VkCopyMicromapModeEXT;
  • VK_COPY_MICROMAP_MODE_CLONE_EXT creates a direct copy of the micromap specified in src into the one specified by dst. The dst micromap must have been created with the same parameters as src.
  • VK_COPY_MICROMAP_MODE_SERIALIZE_EXT serializes the micromap to a semi-opaque format which can be reloaded on a compatible implementation.
  • VK_COPY_MICROMAP_MODE_DESERIALIZE_EXT deserializes the semi-opaque serialization format in the buffer to the micromap.
  • VK_COPY_MICROMAP_MODE_COMPACT_EXT creates a more compact version of a micromap src into dst. The micromap dst must have been created with a size at least as large as that returned by vkCmdWriteMicromapsPropertiesEXT after the build of the micromap specified by src.
