# VkAccelerationStructureMemoryRequirementsTypeNV(3) Manual Page

## Name

VkAccelerationStructureMemoryRequirementsTypeNV - Acceleration structure memory requirement type

## C Specification

Possible values of `type` in `VkAccelerationStructureMemoryRequirementsInfoNV` are:,

    typedef enum VkAccelerationStructureMemoryRequirementsTypeNV {
        VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_NV = 0,
        VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_NV = 1,
        VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_NV = 2,
        VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_MAX_ENUM_NV = 0x7FFFFFFF
    } VkAccelerationStructureMemoryRequirementsTypeNV;

## Description

- `VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_OBJECT_NV` requests the memory requirement for the `VkAccelerationStructureNV` backing store.

- `VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_BUILD_SCRATCH_NV` requests the memory requirement for scratch space during the initial build.

- `VK_ACCELERATION_STRUCTURE_MEMORY_REQUIREMENTS_TYPE_UPDATE_SCRATCH_NV` requests the memory requirement for scratch space during an update.
