VkClusterAccelerationStructureOpTypeNV

Enum providing the type of operation

Values which can be set in VkClusterAccelerationStructureOpTypeNV are:

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,
} VkClusterAccelerationStructureOpTypeNV;
  • 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 indicates that bottom level cluster acceleration structures will be built.
  • VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_NV indicates that cluster acceleration structures will be built.
  • VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_TEMPLATE_NV indicates that a template for cluster acceleration structure will be built.
  • VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_INSTANTIATE_TRIANGLE_CLUSTER_NV indicates that a template for a cluster acceleration structure will be instantiated, resulting in a built cluster acceleration structure.
