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 a VkStructureType value identifying 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.
