# VkBuildAccelerationStructureModeKHR(3) Manual Page

## Name

VkBuildAccelerationStructureModeKHR - Enum specifying the type of build operation to perform

## C Specification

The VkBuildAccelerationStructureModeKHR enumeration is defined as:

    // Provided by VK_KHR_acceleration_structure
    typedef enum VkBuildAccelerationStructureModeKHR {
        VK_BUILD_ACCELERATION_STRUCTURE_MODE_BUILD_KHR = 0,
        VK_BUILD_ACCELERATION_STRUCTURE_MODE_UPDATE_KHR = 1,
    } VkBuildAccelerationStructureModeKHR;

## Description

- VK_BUILD_ACCELERATION_STRUCTURE_MODE_BUILD_KHR specifies that the destination acceleration structure will be built using the specified geometries.

- VK_BUILD_ACCELERATION_STRUCTURE_MODE_UPDATE_KHR specifies that the destination acceleration structure will be built using data in a source acceleration structure, updated by the specified geometries.
