To query micromap size parameters on the host, call:
// Provided by VK_EXT_opacity_micromap VkResult vkWriteMicromapsPropertiesEXT( VkDevice device, uint32_t micromapCount, const VkMicromapEXT* pMicromaps, VkQueryType queryType, size_t dataSize, void* pData, size_t stride);
deviceis the device which owns the micromaps in
micromapCountis the count of micromaps for which to query the property.
pMicromapsis a pointer to an array of existing previously built micromaps.
queryTypeis a VkQueryType value specifying the property to be queried.
dataSizeis the size in bytes of the buffer pointed to by
pDatais a pointer to a user-allocated buffer where the results will be written.
strideis the stride in bytes between results for individual queries within
This command fulfills the same task as vkCmdWriteMicromapsPropertiesEXT but is executed by the host.
