vkCmdBuildAccelerationStructuresKHR

To build acceleration structures call:

void vkCmdBuildAccelerationStructuresKHR(
    VkCommandBuffer                                    commandBuffer,
    uint32_t infoCount,
    const VkAccelerationStructureBuildGeometryInfoKHR* pInfos,
    const VkAccelerationStructureBuildRangeInfoKHR* const* ppBuildRangeInfos);

commandBuffer is the command buffer into which the command will be recorded.
infoCount is the number of acceleration structures to build. It specifies the number of the pInfos structures and ppBuildRangeInfos pointers that must be provided.
pInfos is a pointer to an array of infoCount
VkAccelerationStructureBuildGeometryInfoKHR structures defining the geometry used to build each acceleration structure.
ppBuildRangeInfos is a pointer to an array of infoCount pointers to arrays of VkAccelerationStructureBuildRangeInfoKHR structures. Each ppBuildRangeInfos[i] is a pointer to an array of pInfos[i].geometryCount
VkAccelerationStructureBuildRangeInfoKHR structures defining dynamic offsets to the addresses where geometry data is stored, as defined by pInfos[i].

The vkCmdBuildAccelerationStructuresKHR command provides the ability to initiate multiple acceleration structures builds, however there is no ordering or synchronization implied between any of the individual acceleration structure builds.

This means that an application cannot build a top-level acceleration structure in the same vkCmdBuildAccelerationStructuresKHR call as the associated bottom-level or instance acceleration structures are being built. There also cannot be any memory aliasing between any acceleration structure memories or scratch memories being used by any of the builds.

Accesses to the acceleration structure scratch buffers as identified by the VkAccelerationStructureBuildGeometryInfoKHR::scratchData buffer device addresses 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 VkAccelerationStructureBuildGeometryInfoKHR::srcAccelerationStructure and VkAccelerationStructureBuildGeometryInfoKHR::dstAccelerationStructuremust 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 or VK_ACCESS_ACCELERATION_STRUCTURE_WRITE_BIT_KHR, as appropriate.

Accesses to other input buffers as identified by any used values of VkAccelerationStructureGeometryMotionTrianglesDataNV::vertexData, VkAccelerationStructureGeometryTrianglesDataKHR::vertexData, VkAccelerationStructureGeometryTrianglesDataKHR::indexData, VkAccelerationStructureGeometryTrianglesDataKHR::transformData, VkAccelerationStructureGeometryAabbsDataKHR::data, and VkAccelerationStructureGeometryInstancesDataKHR::data must be synchronized with the VK_PIPELINE_STAGE_ACCELERATION_STRUCTURE_BUILD_BIT_KHR

pipeline stage and an access type of VK_ACCESS_SHADER_READ_BIT.
