Data is owned by the instance, meaning it stays in scope for as long as the instance. If neither DataFlag::Owned, DataFlag::ExternallyOwned nor DataFlag::Global is set, the data is considered to be just a temporary allocation and no assumptions about its lifetime can be made.

Data has an owner external to the instance, for example a memory-mapped file or a constant memory. In general the data lifetime exceeds lifetime of the instance wrapping it. If neither DataFlag::Owned, DataFlag::ExternallyOwned nor DataFlag::Global is set, the data is considered to be just a temporary allocation and no assumptions about its lifetime can be made.

Data is global, for example stored in static memory, so guaranteed to never go out of scope. Usually such data are not DataFlag::Mutable. If neither DataFlag::Owned, DataFlag::ExternallyOwned nor DataFlag::Global is set, the data is considered to be just a temporary allocation and no assumptions about its lifetime can be made.

Data is mutable. If this flag is not set, the instance might be for example referencing a readonly memory-mapped file or a constant memory.

Ambient light, without any position, direction or attenuation. Meant to be added to ambient color in Phong workflows, has no use in physically based workflows.

Light at a position that is infinitely far away, emitted in a direction of negative Z axis. The rotation is inherited from absolute object transformation; scale and position don't affect the light in any way. Because the light is at infinite distance, it's not attenuated in any way.

Directional light.

Point light, emitting light in all directions. The position is inherited from absolute object transformation; scale and rotation don't affect the light in any way. Brightness attenuates depending on the LightData::range() value.

Spot light, emitting light in a cone in direction of local negative Z axis. The position and rotation is inherited from absolute object transformation; scale doesn't affect the light in any way. The angle and falloff of the cone is defined using LightData::innerConeAngle() and LightData::outerConeAngle() and brightness attenuates depending on the LightData::range() value.

UnsignedShort

UnsignedInt

UnsignedLong

Parent object. Type is usually SceneFieldType::Int, but can be also any of Byte, Short or a Long. A value of -1 means there's no parent. An object should have only one parent, altough this isn't enforced in any way, and which of the duplicate fields gets used is not defined.

Type is usually SceneFieldType::Matrix3x3 for 2D and SceneFieldType::Matrix4x4 for 3D, but can be also any of Matrix3x3d, Matrix3x2 or Matrix3x2d (with the bottom row implicitly assumed to be ), DualComplex or DualComplexd for 2D and Matrix4x4d, Matrix4x3 or Matrix4x3d (with the bottom row implicitly assumed to be ), DualQuaternion or DualQuaterniond for 3D. An object should have only one transformation, altough this isn't enforced in any way, and which of the duplicate fields gets used is not defined.

The transformation can be also represented by separate SceneField::Translation, SceneField::Rotation and SceneField::Scaling fields. All present transformation-related fields are expected to have the same dimensionality — either all 2D or all 3D. If both SceneField::Transformation and TRS fields are specified, it's expected that all objects that have TRS fields have a combined transformation field as well, and SceneData::transformations2DAsArray() / SceneData::transformations3DAsArray() then takes into account only the combined transformation field. TRS fields can however be specified only for a subset of transformed objects, useful for example when only certain objects have these properties animated.

Translation. Type is usually SceneFieldType::Vector2 for 2D and SceneFieldType::Vector3 for 3D, but can be also any of Vector2d for 2D and Vector3d for 3D. An object should have only one translation, altough this isn't enforced in any way, and which of the duplicate fields gets used is not defined.

Scaling. Type is usually SceneFieldType::Vector2 for 2D and SceneFieldType::Vector3 for 3D, but can be also any of Vector2d for 2D and Vector3d for 3D. An object should have only one scaling, altough this isn't enforced in any way, and which of the duplicate fields gets used is not defined.

The scaling field usually is (but doesn't have to be) complemented by a SceneField::Translation and SceneField::Rotation, which, if present, are expected to all share the same object mapping view and have the same dimensionality, either all 2D or all 3D. The TRS components can either completely replace SceneField::Transformation or be provided just for a subset of it — see its documentation for details.

ID of a mesh associated with this object, corresponding to the ID passed to AbstractImporter::mesh(). Type is usually SceneFieldType::UnsignedInt, but can be also any of UnsignedByte or UnsignedShort. An object can have multiple meshes associated.

Usually complemented with a SceneField::MeshMaterial, although not required. If present, both should share the same object mapping view. Objects with multiple meshes then have the Nth mesh associated with the Nth material.

ID of a camera associated with this object, corresponding to the ID passed to AbstractImporter::camera(). Type is usually SceneFieldType::UnsignedInt, but can be also any of UnsignedByte or UnsignedShort. An object can have multiple cameras associated.

ID of a skin associated with this object, corresponding to the ID passed to AbstractImporter::skin2D() or AbstractImporter::skin3D(), depending on whether the scene has a 2D or 3D transformation. Type is usually SceneFieldType::UnsignedInt, but can be also any of UnsignedByte or UnsignedShort. An object can have multiple skins associated.

Importer state for given object, per-object counterpart to scene-specific SceneData::importerState(). Type is usually SceneFieldType::Pointer but can be also SceneFieldType::MutablePointer. An object should have only one importer state, altough this isn't enforced in any way, and which of the duplicate fields gets used is not defined.

32-bit string offsets with implicit sizes. Use SceneData::fieldStrings() for convenient access.

Internally, the first string starts at SceneData::fieldStringData(), second string starts at fieldStringData() plus field<UnsignedInt>()[0], etc. String sizes are implicitly the distance between two successive offsets or field<UnsignedInt>()[0] in case of the first string; if SceneFieldFlag::NullTerminatedString is set the distance includes the null terminator.

The StringOffset* types are useful mainly for cases where each string is unique, for strings with many duplicates SceneFieldType::StringRange* or StringRangeNullTerminated32* may be a more space-efficient option.

8-bit string offsets with implicit sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringOffset32 except that UnsignedByte is used as the type, see its documentation for more information.

16-bit string offsets with implicit sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringOffset32 except that UnsignedShort is used as the type, see its documentation for more information.

64-bit string offsets with implicit sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringOffset32 except that UnsignedLong is used as the type, see its documentation for more information.

Containers::Pair of 32-bit string offsets and sizes. Use SceneData::fieldStrings() for convenient access.

Internally, string i starts at SceneData::fieldStringData() plus field<Containers::Pair<UnsignedInt, UnsignedInt>>()[i].first() and has a size of field<Containers::Pair<UnsignedInt, UnsignedInt>>()[i].second().

The main use case for StringRange* types is to be able to reference the same string from multiple field entries without having to duplicate it. For strings without duplicates SceneFieldType::StringOffset* may be a more space-efficient option, as the size is implicit. Alternatively, StringRangeNullTerminated32* has the same space requirements as StringOffset* with SceneFieldFlag::NullTerminatedString set and allows deduplication, however at the cost of a std::strlen() call on every access.

Containers::Pair of 8-bit string offsets and sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringRange32 except that UnsignedByte is used for the pair types, see its documentation for more information.

Containers::Pair of 16-bit string offsets and sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringRange32 except that UnsignedShort is used for the pair types, see its documentation for more information.

Containers::Pair of 64-bit string offsets and sizes. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringRange32 except that UnsignedLong is used for the pair types, see its documentation for more information.

32-bit offsets to null-terminated strings. Use SceneData::fieldStrings() for convenient access.

Compared to SceneFieldType::StringRange32 stores just the offset, the size is calculated on-the-fly with std::strlen().

Internally, string i starts at SceneData::fieldStringData() plus field<UnsignedInt>()[i], size is implicitly until the first '\0' byte. See SceneFieldType::StringRange32 for use case recommendations.

8-bit offsets to null-terminated strings. Use SceneData::fieldStrings() for convenient access.

The internal layout is similar to SceneFieldType::StringRangeNullTerminated32 except that UnsignedByte is used as the type, see its documentation for more information.

The field is offset-only, i.e. doesn't contain the data views directly but referes to unspecified external data. Set implicitly by the SceneFieldData::SceneFieldData(SceneField, std::size_t, SceneMappingType, std::size_t, std::ptrdiff_t, SceneFieldType, std::size_t, std::ptrdiff_t, UnsignedShort, SceneFieldFlags) constructor, can't be used for any other constructor.

The field has an ordered object mapping, i.e. a monotonically increasing sequence. Object IDs in fields marked with this flag can be looked up with an complexity, gaps and duplicates are possible.

Note that validity of the object mapping data isn't checked in any way and if the data doesn't correspond to rules of the flag, queries such as SceneData::findFieldObjectOffset() may return a wrong value.

If a field has neither this nor the SceneFieldFlag::ImplicitMapping flag, it's assumed to be unordered, with an lookup complexity.

The field has an implicit object mapping, i.e. a contiguous sequence from 0 up to size of the field. A superset of SceneFieldFlag::OrderedMapping. Object IDs in fields marked with this flag can be looked up with an complexity, but the field is restricted to exactly one value for each object.

Note that validity of the object mapping data isn't checked in any way and if the data doesn't correspond to rules of the flag, queries such as SceneData::findFieldObjectOffset() may return a wrong value.

If a field has neither this nor the SceneFieldFlag::OrderedMapping flag, it's assumed to be unordered, with an lookup complexity.

The string field is null-terminated, i.e. string views returned from SceneData::fieldStrings() will always have Containers::StringViewFlag::NullTerminated set. Internally it means that the distance between successive SceneFieldType::StringOffset* entries includes the null terminator; SceneFieldType::StringRange* size is excluding the null terminator but assumes it's present right after; for SceneFieldType,StringRangeNullTerminated* it's set implicitly as that's the default behavior.

Can only be set for string SceneFieldType.
