## Name

VkClusterAccelerationStructureOpTypeNV - Enum providing the type of operation

Loading… please wait.

## C Specification

Values which can be set in `VkClusterAccelerationStructureOpTypeNV` are:

    // Provided by VK_NV_cluster_acceleration_structure
    typedef enum VkClusterAccelerationStructureOpTypeNV {
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_MOVE_OBJECTS_NV = 0,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_CLUSTERS_BOTTOM_LEVEL_NV = 1,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_NV = 2,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_TEMPLATE_NV = 3,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_INSTANTIATE_TRIANGLE_CLUSTER_NV = 4,
        VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_GET_CLUSTER_TEMPLATE_INDICES_NV = 5,
    } VkClusterAccelerationStructureOpTypeNV;

## Description

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_MOVE_OBJECTS_NV` specifies that a cluster acceleration structure, cluster acceleration structure template or a bottom level acceleration structure built from cluster acceleration structures will be moved. If a cluster acceleration structure is moved, the bottom level cluster acceleration structures containing it will have to be re-built. If used with `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV`, it returns the size of existing cluster acceleration structures.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_CLUSTERS_BOTTOM_LEVEL_NV` specifies that bottom level cluster acceleration structures will be built.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_NV` specifies that cluster acceleration structures will be built.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_TEMPLATE_NV` specifies that a template for cluster acceleration structure will be built.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_INSTANTIATE_TRIANGLE_CLUSTER_NV` specifies that a template for a cluster acceleration structure will be instantiated, resulting in a built cluster acceleration structure.

- `VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_GET_CLUSTER_TEMPLATE_INDICES_NV` specifies that the vertex indices of the cluster template acceleration structure will be fetched.
