C Specification
The VkAccelerationStructureMemoryRequirementsInfoKHR
structure is
defined as:
// Provided by VK_KHR_ray_tracing
typedef struct VkAccelerationStructureMemoryRequirementsInfoKHR {
VkStructureType sType;
const void* pNext;
VkAccelerationStructureMemoryRequirementsTypeKHR type;
VkAccelerationStructureBuildTypeKHR buildType;
VkAccelerationStructureKHR accelerationStructure;
} VkAccelerationStructureMemoryRequirementsInfoKHR;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
buildType
selects the build types whose memory requirements are being queried. -
type
selects the type of memory requirement being queried.VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_KHR
returns the memory requirements for the object itself.VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_KHR
returns the memory requirements for the scratch memory when doing a build.VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_KHR
returns the memory requirements for the scratch memory when doing an update. -
accelerationStructure
is the acceleration structure to be queried for memory requirements.
