VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV(3)

Name

VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV - Parameters describing build operation for a bottom level cluster acceleration structure

C Specification

The VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV structure is defined as:

// Provided by VK_NV_cluster_acceleration_structure
typedef struct VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV {
    uint32_t           clusterReferencesCount;
    uint32_t           clusterReferencesStride;
    VkDeviceAddress    clusterReferences;
} VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV;

Members

  • clusterReferencesCount is the number of clusters this bottom level acceleration structure will be built from.

  • clusterReferencesStride is the stride in clusterReferences.

  • clusterReferences is the device memory containing the address of the clusters.

Description

Valid Usage

  • VUID-VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV-clusterReferences-10484
    All cluster references in clusterReferences must be unique

  • VUID-VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV-clusterReferences-10485
    clusterReferences must have at least clusterReferencesCount values

  • VUID-VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV-clusterReferencesStride-10486
    clusterReferencesStride must be greater than or equal to 8

Valid Usage (Implicit)

  • VUID-VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV-clusterReferences-parameter
    clusterReferences must be a valid VkDeviceAddress value
