VkAccelerationStructureCreateInfoNV(3)

Name

VkAccelerationStructureCreateInfoNV - Structure specifying the parameters of a newly created acceleration structure object

C Specification

The VkAccelerationStructureCreateInfoNV structure is defined as:

// Provided by VK_NV_ray_tracing
typedef struct VkAccelerationStructureCreateInfoNV {
    VkStructureType                  sType;
    const void*                      pNext;
    VkDeviceSize                     compactedSize;
    VkAccelerationStructureInfoNV    info;
} VkAccelerationStructureCreateInfoNV;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
compactedSize is the size from the result of vkCmdWriteAccelerationStructuresPropertiesNV if this acceleration structure is going to be the target of a compacting copy.
info is the VkAccelerationStructureInfoNV structure specifying further parameters of the created acceleration structure.

Description

Valid Usage

VUID-VkAccelerationStructureCreateInfoNV-compactedSize-02421
If compactedSize is not 0 then both info.geometryCount and info.instanceCount must be 0

Valid Usage (Implicit)

VUID-VkAccelerationStructureCreateInfoNV-sType-sType
sType must be VK_STRUCTURE_TYPE_ACCELERATION_STRUCTURE_CREATE_INFO_NV
VUID-VkAccelerationStructureCreateInfoNV-pNext-pNext
pNext must be NULL or a pointer to a valid instance of VkOpaqueCaptureDescriptorDataCreateInfoEXT
VUID-VkAccelerationStructureCreateInfoNV-sType-unique
The sType value of each structure in the pNext chain must be unique
VUID-VkAccelerationStructureCreateInfoNV-info-parameter
info must be a valid VkAccelerationStructureInfoNV structure
