# VkClusterAccelerationStructureClustersBottomLevelInputNV(3) Manual Page

## Name

VkClusterAccelerationStructureClustersBottomLevelInputNV - Parameters describing bottom level acceleration structure

Loading… please wait.

## C Specification

The VkClusterAccelerationStructureClustersBottomLevelInputNV structure is defined as:

    // Provided by VK_NV_cluster_acceleration_structure
    typedef struct VkClusterAccelerationStructureClustersBottomLevelInputNV {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxTotalClusterCount;
        uint32_t           maxClusterCountPerAccelerationStructure;
    } VkClusterAccelerationStructureClustersBottomLevelInputNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `maxTotalClusterCount` is the total number of clusters acceleration structures that will be built or moved across all input arguments.

- `maxClusterCountPerAccelerationStructure` is the maximum number of clusters acceleration structures that will be built or moved per input argument.

## Description

Valid Usage (Implicit)

- VUID-VkClusterAccelerationStructureClustersBottomLevelInputNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_CLUSTER_ACCELERATION_STRUCTURE_CLUSTERS_BOTTOM_LEVEL_INPUT_NV`

- VUID-VkClusterAccelerationStructureClustersBottomLevelInputNV-pNext-pNext
  `pNext` must be `NULL`
