Typedef Documentation

◆ FeatureIdAccessorType

typedef std::variant< AccessorView<int8_t>, AccessorView<uint8_t>, AccessorView<int16_t>, AccessorView<uint16_t>, AccessorView<uint32_t>, AccessorView<float> > CesiumGltf::FeatureIdAccessorType

Type definition for all kinds of feature ID attribute accessors.

Definition at line 75 of file AccessorUtility.h.

◆ IndexAccessorType

typedef std::variant< std::monostate, AccessorView<uint8_t>, AccessorView<uint16_t>, AccessorView<uint32_t> > CesiumGltf::IndexAccessorType

Type definition for all kinds of index accessors. std::monostate indicates a nonexistent accessor, which can happen (and is valid) if the primitive vertices are defined without an index buffer.

Definition at line 134 of file AccessorUtility.h.

◆ NormalAccessorType

typedef AccessorView<AccessorTypes::VEC3<float> > CesiumGltf::NormalAccessorType

Type definition for normal accessor.

Definition at line 55 of file AccessorUtility.h.

◆ PositionAccessorType

typedef AccessorView<AccessorTypes::VEC3<float> > CesiumGltf::PositionAccessorType

Type definition for position accessor.

Definition at line 42 of file AccessorUtility.h.

◆ PropertyValueViewToCopy

template<typename T >

using CesiumGltf::PropertyValueViewToCopy = typedef std::conditional_t< IsMetadataNumericArray<T>::value, PropertyArrayCopy<typename MetadataArrayType<T>::type>, T>

Transforms a property value type from a view to an equivalent type that owns the data it is viewing. For most property types this is an identity transformation, because most property types are held by value. However, it transforms numeric PropertyArrayView<T> to PropertyArrayCopy<T> because a PropertyArrayView<T> only has a pointer to the value it is viewing.

Template Parameters

T	The type of the property value view.

Definition at line 388 of file PropertyTypeTraits.h.

◆ QuaternionAccessorType

typedef std::variant< AccessorView<AccessorTypes::VEC4<uint8_t> >, AccessorView<AccessorTypes::VEC4<int8_t> >, AccessorView<AccessorTypes::VEC4<uint16_t> >, AccessorView<AccessorTypes::VEC4<int16_t> >, AccessorView<AccessorTypes::VEC4<float> > > CesiumGltf::QuaternionAccessorType

Type definition for quaternion accessors, as used in ExtMeshGpuInstancing rotations and animation samplers.

Definition at line 332 of file AccessorUtility.h.

◆ TexCoordAccessorType

typedef std::variant< AccessorView<AccessorTypes::VEC2<uint8_t> >, AccessorView<AccessorTypes::VEC2<uint16_t> >, AccessorView<AccessorTypes::VEC2<float> > > CesiumGltf::TexCoordAccessorType

Type definition for all kinds of texture coordinate (TEXCOORD_n) accessors.

Definition at line 273 of file AccessorUtility.h.

Enumeration Type Documentation

◆ AccessorViewStatus

enum CesiumGltf::AccessorViewStatus

strong

Indicates the status of an accessor view.

The AccessorView constructor always completes successfully. However, it may not always reflect the actual content of the Accessor, but instead indicate that its AccessorView::size is 0. This enumeration provides the reason.

Enumerator
Valid	This accessor is valid and ready to use.
InvalidAccessorIndex	The accessor index does not refer to a valid accessor.
InvalidBufferViewIndex	The accessor's bufferView index does not refer to a valid bufferView.
InvalidBufferIndex	The accessor's bufferView's buffer index does not refer to a valid buffer.
BufferViewTooSmall	The accessor is too large to fit in its bufferView.
BufferTooSmall	The accessor's bufferView is too large to fit in its buffer.
WrongSizeT	The `sizeof(T)` does not match the accessor's Accessor::computeBytesPerVertex.
InvalidType	The Accessor:type is invalid.
InvalidComponentType	The Accessor::componentType is invalid.

Definition at line 18 of file AccessorView.h.

◆ FeatureIdTextureViewStatus

enum CesiumGltf::FeatureIdTextureViewStatus

strong

The status of a feature ID texture view.

The FeatureIdTextureView constructor always completes successfully, but it may not always reflect the actual content of the FeatureIdTexture. This enumeration provides the reason.

Enumerator
Valid	This view is valid and ready to use.
ErrorUninitialized	This view has not yet been initialized.
ErrorInvalidTexture	This feature ID texture has a texture index that doesn't exist in the glTF.
ErrorInvalidImage	This feature ID texture has an image index that doesn't exist in the glTF.
ErrorInvalidSampler	This feature ID texture has a sampler index that doesn't exist in the glTF.
ErrorEmptyImage	This feature ID texture has an empty image.
ErrorInvalidImageBytesPerChannel	The image for this feature ID texture has channels that take up more than a byte. Only single-byte channels are supported.
ErrorInvalidChannels	The channels of this feature ID texture property are invalid. Channels must be in the range 0-3, with a minimum of one channel. Although more than four channels can be defined for specialized texture formats, this view only supports a maximum of four channels.

Definition at line 19 of file FeatureIdTextureView.h.

◆ KhrTextureTransformStatus

enum CesiumGltf::KhrTextureTransformStatus

strong

The status of a parsed KHR_texture_transform.

Definition at line 15 of file KhrTextureTransform.h.

◆ PropertyAttributeViewStatus

enum CesiumGltf::PropertyAttributeViewStatus

strong

Indicates the status of a property attribute view.

The PropertyAttributeView constructor always completes successfully. However it may not always reflect the actual content of the PropertyAttribute. This enumeration provides the reason.

Enumerator
Valid	This property attribute view is valid and ready to use.
ErrorMissingMetadataExtension	The glTF is missing the EXT_structural_metadata extension.
ErrorMissingSchema	The glTF EXT_structural_metadata extension doesn't contain a schema.
ErrorClassNotFound	The property attribute's specified class could not be found in the extension.

Definition at line 18 of file PropertyAttributeView.h.

◆ PropertyTableViewStatus

enum CesiumGltf::PropertyTableViewStatus

strong

Indicates the status of a property table view.

The PropertyTableView constructor always completes successfully. However, it may not always reflect the actual content of the PropertyTable, but instead indicate that its PropertyTableView::size is 0. This enumeration provides the reason.

Enumerator
Valid	This property table view is valid and ready to use.
ErrorMissingMetadataExtension	The property table view's model does not contain an EXT_structural_metadata extension.
ErrorMissingSchema	The property table view's model does not have a schema in its EXT_structural_metadata extension.
ErrorClassNotFound	The property table's specified class could not be found in the extension.

Definition at line 22 of file PropertyTableView.h.

◆ PropertyTextureViewStatus

enum CesiumGltf::PropertyTextureViewStatus

strong

Indicates the status of a property texture view.

The PropertyTextureView constructor always completes successfully. However it may not always reflect the actual content of the PropertyTexture. This enumeration provides the reason.
