VkAccelerationStructureBuildSizesInfoKHR

The VkAccelerationStructureBuildSizesInfoKHR structure describes the required build sizes for an acceleration structure and scratch buffers and is defined as:

typedef struct VkAccelerationStructureBuildSizesInfoKHR {
    VkStructureType sType;
    void* pNext;
    VkDeviceSize accelerationStructureSize;
    VkDeviceSize updateScratchSize;
    VkDeviceSize buildScratchSize;
} VkAccelerationStructureBuildSizesInfoKHR;

pub struct AccelerationStructureBuildSizesInfoKHR {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    acceleration_structure_size: vk::DeviceSize,
    update_scratch_size: vk::DeviceSize,
    build_scratch_size: vk::DeviceSize,
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• accelerationStructureSize is the size in bytes required in a VkAccelerationStructureKHR for a build or update operation.
• updateScratchSize is the size in bytes required in a scratch buffer for an update operation.
• buildScratchSize is the size in bytes required in a scratch buffer for a build operation.
