VkAccelerationStructureMemoryRequirementsInfoNV

The VkAccelerationStructureMemoryRequirementsInfoNV structure is defined as:

typedef struct VkAccelerationStructureMemoryRequirementsInfoNV {
    VkStructureType sType;
    const void* pNext;
    VkAccelerationStructureMemoryRequirementsTypeNV type;
    VkAccelerationStructureNV accelerationStructure;
} VkAccelerationStructureMemoryRequirementsInfoNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• type selects the type of memory requirement being queried. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_NV returns the memory requirements for the object itself. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_NV returns the memory requirements for the scratch memory when doing a build. VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_NV returns the memory requirements for the scratch memory when doing an update.
• accelerationStructure is the acceleration structure to be queried for memory requirements.
