C Specification

Possible values of type in VkAccelerationStructureMemoryRequirementsInfoNV are:,

// Provided by VK_NV_ray_tracing
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,
} 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.
