vkCmdBuildClusterAccelerationStructureIndirectNV

To build or move a cluster acceleration structure or a cluster acceleration structure template call:

void vkCmdBuildClusterAccelerationStructureIndirectNV(
    VkCommandBuffer                     commandBuffer,
    const VkClusterAccelerationStructureCommandsInfoNV*  pCommandInfos);

• commandBuffer is the command buffer into which the command is recorded.
• pCommandInfos is a pointer to a VkClusterAccelerationStructureCommandsInfoNV structure containing parameters required for building or moving the cluster acceleration structure.

Similar to vkCmdBuildAccelerationStructuresKHR, this command may initiate multiple acceleration structures builds and there is no ordering or synchronization implied between any of the individual acceleration structure builds. Accesses to the acceleration structure scratch memory as identified by the VkClusterAccelerationStructureCommandsInfoNV::scratchData must be synchronized with the VK_PIPELINE_STAGE_ACCELERATION_STRUCTURE_BUILD_BIT_KHR

pipeline stage and an access type of (VK_ACCESS_ACCELERATION_STRUCTURE_READ_BIT_KHR | VK_ACCESS_ACCELERATION_STRUCTURE_WRITE_BIT_KHR).

Accesses to each VkClusterAccelerationStructureCommandsInfoNV::dstImplicitData, VkClusterAccelerationStructureCommandsInfoNV::dstAddressesArray and VkClusterAccelerationStructureCommandsInfoNV::dstSizesArraymust be synchronized with the VK_PIPELINE_STAGE_ACCELERATION_STRUCTURE_BUILD_BIT_KHR

pipeline stage and an access type of VK_ACCESS_ACCELERATION_STRUCTURE_WRITE_BIT_KHR.

Accesses to memory with input data as identified by any used values of VkClusterAccelerationStructureCommandsInfoNV::srcInfosArray, VkClusterAccelerationStructureCommandsInfoNV::srcInfosCount and VkClusterAccelerationStructureCommandsInfoNV::addressResolutionFlagsmust be synchronized with the VK_PIPELINE_STAGE_ACCELERATION_STRUCTURE_BUILD_BIT_KHR

pipeline stage and an access type of VK_ACCESS_INDIRECT_COMMAND_READ_BIT.
