VkPartitionedAccelerationStructureInstanceFlagBitsNV

Bits which can be set in VkPartitionedAccelerationStructureWriteInstanceDataNV::instanceFlags, specifying flags for instances, are:

typedef enum VkPartitionedAccelerationStructureInstanceFlagBitsNV {
    VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_TRIANGLE_FACING_CULL_DISABLE_BIT_NV = 0x00000001,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_TRIANGLE_FLIP_FACING_BIT_NV = 0x00000002,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_FORCE_OPAQUE_BIT_NV = 0x00000004,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_FORCE_NO_OPAQUE_BIT_NV = 0x00000008,
    VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_ENABLE_EXPLICIT_BOUNDING_BOX_NV = 0x00000010,
} VkPartitionedAccelerationStructureInstanceFlagBitsNV;

• VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_TRIANGLE_FACING_CULL_DISABLE_BIT_NV disables face culling for this instance.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_TRIANGLE_FLIP_FACING_BIT_NV indicates that the facing determination for geometry in this instance is inverted.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_FORCE_OPAQUE_BIT_NV causes this instance to act as though VK_GEOMETRY_OPAQUE_BIT_KHR were specified on all geometries referenced by this instance.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_FORCE_NO_OPAQUE_BIT_NV causes this instance to act as though VK_GEOMETRY_OPAQUE_BIT_KHR were not specified on all geometries referenced by this instance.
• VK_PARTITIONED_ACCELERATION_STRUCTURE_INSTANCE_FLAG_ENABLE_EXPLICIT_BOUNDING_BOX_NV enables use of an explicit bounding box for this instance.
