C Specification

Values which can be set in VkAccelerationStructureInfoNV::type, specifying the type of acceleration structure, are:

typedef enum VkAccelerationStructureTypeNV {
    VK_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL_NV = 0,
    VK_ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL_NV = 1,
    VK_ACCELERATION_STRUCTURE_TYPE_MAX_ENUM_NV = 0x7FFFFFFF
} VkAccelerationStructureTypeNV;

Description

  • VK_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL_NV is a top-level acceleration structure containing instance data referring to bottom-level level acceleration structures.

  • VK_ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL_NV is a bottom-level acceleration structure containing the AABBs or geometry to be intersected.
