# VkClusterAccelerationStructureOpModeNV(3) Manual Page

## Name

VkClusterAccelerationStructureOpModeNV - Enum providing the mode of operation

Loading… please wait.

## C Specification

Values which can be set in `VkClusterAccelerationStructureOpModeNV` are:

    // Provided by VK_NV_cluster_acceleration_structure
    typedef enum VkClusterAccelerationStructureOpModeNV {
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV = 0,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV = 1,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV = 2,
    } VkClusterAccelerationStructureOpModeNV;

## Description

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV` specifies that the build or move operation will implicitly distribute built or compacted cluster acceleration structures starting at the address provided in VkClusterAccelerationStructureCommandsInfoNV::`dstImplicitData`. If a move operation is being performed, the acceleration structures will be tightly compacted.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV` specifies that the build or move operation will explicitly write built or compacted cluster acceleration structures in the array of addresses provided in VkClusterAccelerationStructureCommandsInfoNV::`dstAddressesArray`.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV` specifies that computed cluster acceleration structure sizes will be written to VkClusterAccelerationStructureCommandsInfoNV::`dstSizesArray`.
