VkAccelerationStructureVersionInfoKHR(3)

Name

VkAccelerationStructureVersionInfoKHR - Acceleration structure version information

C Specification

The VkAccelerationStructureVersionInfoKHR structure is defined as:

// Provided by VK_KHR_acceleration_structure
typedef struct VkAccelerationStructureVersionInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    const uint8_t*     pVersionData;
} VkAccelerationStructureVersionInfoKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
pVersionData is a pointer to the version header of an acceleration structure as defined in vkCmdCopyAccelerationStructureToMemoryKHR

Description

pVersionData is a pointer to an array of 2×VK_UUID_SIZE uint8_t values instead of two VK_UUID_SIZE arrays as the expected use case for this member is to be pointed at the header of a previously serialized acceleration structure (via vkCmdCopyAccelerationStructureToMemoryKHR or vkCopyAccelerationStructureToMemoryKHR) that is loaded in memory. Using arrays would necessitate extra memory copies of the UUIDs.

Valid Usage (Implicit)

VUID-VkAccelerationStructureVersionInfoKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_ACCELERATION_STRUCTURE_VERSION_INFO_KHR
VUID-VkAccelerationStructureVersionInfoKHR-pNext-pNext
pNext must be NULL
VUID-VkAccelerationStructureVersionInfoKHR-pVersionData-parameter
pVersionData must be a valid pointer to an array of uint8_t values
