C Specification

Possible values of buildType in vkGetAccelerationStructureBuildSizesKHR are:

// Provided by VK_KHR_acceleration_structure
typedef enum VkAccelerationStructureBuildTypeKHR {
    VK_ACCELERATION_STRUCTURE_BUILD_TYPE_HOST_KHR = 0,
    VK_ACCELERATION_STRUCTURE_BUILD_TYPE_DEVICE_KHR = 1,
    VK_ACCELERATION_STRUCTURE_BUILD_TYPE_HOST_OR_DEVICE_KHR = 2,
} VkAccelerationStructureBuildTypeKHR;

Description

  • VK_ACCELERATION_STRUCTURE_BUILD_TYPE_HOST_KHR requests the memory requirement for operations performed by the host.

  • VK_ACCELERATION_STRUCTURE_BUILD_TYPE_DEVICE_KHR requests the memory requirement for operations performed by the device.

  • VK_ACCELERATION_STRUCTURE_BUILD_TYPE_HOST_OR_DEVICE_KHR requests the memory requirement for operations performed by either the host, or the device.
