VkAccelerationStructureGeometryInstancesDataKHR(3)

Name

VkAccelerationStructureGeometryInstancesDataKHR - Structure specifying a geometry consisting of instances of other acceleration structures

C Specification

The VkAccelerationStructureGeometryInstancesDataKHR structure is defined as:

// Provided by VK_KHR_acceleration_structure
typedef struct VkAccelerationStructureGeometryInstancesDataKHR {
    VkStructureType                  sType;
    const void*                      pNext;
    VkBool32                         arrayOfPointers;
    VkDeviceOrHostAddressConstKHR    data;
} VkAccelerationStructureGeometryInstancesDataKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
arrayOfPointers specifies whether data is used as an array of addresses or just an array.
data is either the address of an array of device or host addresses referencing individual VkAccelerationStructureInstanceKHR structures or packed motion instance information as described in motion instances if arrayOfPointers is VK_TRUE, or the address of an array of VkAccelerationStructureInstanceKHR or VkAccelerationStructureMotionInstanceNV structures. Addresses and VkAccelerationStructureInstanceKHR structures are tightly packed. VkAccelerationStructureMotionInstanceNV structures have a stride of 160 bytes.

Description

Valid Usage (Implicit)

VUID-VkAccelerationStructureGeometryInstancesDataKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_ACCELERATION_STRUCTURE_GEOMETRY_INSTANCES_DATA_KHR
VUID-VkAccelerationStructureGeometryInstancesDataKHR-pNext-pNext
pNext must be NULL
