vkCmdWriteMicromapsPropertiesEXT

To query micromap size parameters call:

void vkCmdWriteMicromapsPropertiesEXT(
    VkCommandBuffer commandBuffer,
    uint32_t micromapCount,
    const VkMicromapEXT* pMicromaps,
    VkQueryType queryType,
    VkQueryPool queryPool,
    uint32_t firstQuery);

• commandBuffer is the command buffer into which the command will be recorded.
• micromapCount is the count of micromaps for which to query the property.
• pMicromaps is a pointer to an array of existing previously built micromaps.
• queryType is a VkQueryType value specifying the type of queries managed by the pool.
• queryPool is the query pool that will manage the results of the query.
• firstQuery is the first query index within the query pool that will contain the micromapCount number of results.

Accesses to any of the micromaps listed in pMicromaps must be synchronized with the VK_PIPELINE_STAGE_2_MICROMAP_BUILD_BIT_EXT

pipeline stage and an access type of VK_ACCESS_2_MICROMAP_READ_BIT_EXT.

• If queryType is VK_QUERY_TYPE_MICROMAP_SERIALIZATION_SIZE_EXT, then the value written out is the number of bytes required by a serialized micromap.
• If queryType is VK_QUERY_TYPE_MICROMAP_COMPACTED_SIZE_EXT, then the value written out is the number of bytes required by a compacted micromap.
