C Specification
The VkAccelerationStructureBuildSizesInfoKHR structure describes the
required build sizes for an acceleration structure and scratch buffers and
is defined as:
// Provided by VK_KHR_acceleration_structure
typedef struct VkAccelerationStructureBuildSizesInfoKHR {
VkStructureType sType;
const void* pNext;
VkDeviceSize accelerationStructureSize;
VkDeviceSize updateScratchSize;
VkDeviceSize buildScratchSize;
} VkAccelerationStructureBuildSizesInfoKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
accelerationStructureSizeis the size in bytes required in a VkAccelerationStructureKHR for a build or update operation. -
updateScratchSizeis the size in bytes required in a scratch buffer for an update operation. -
buildScratchSizeis the size in bytes required in a scratch buffer for a build operation.
