Enumeration Type Documentation

AccessorViewStatus

enum class 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.

transformNormalizedVecNArray()

template<glm::length_t N, typename T>

PropertyArrayCopy< glm::vec< N, double > > CesiumGltf::transformNormalizedVecNArray	(	const PropertyArrayView< glm::vec< N, T > > &	value,
		const std::optional< PropertyArrayView< glm::vec< N, double > > > &	offset,
		const std::optional< PropertyArrayView< glm::vec< N, double > > > &	scale )

Normalizes each element of an array of vectors and transforms them by optional offset and scale factors. See transformNormalizedArray.

Parameters

value	The array whose elements will be transformed.
offset	The amount to offset each element by, or std::nullopt to apply no offset. The offset will be applied after normalization.
scale	The amount to scale each element by, or std::nullopt to apply no scale factor. The scale will be applied after normalization.

Returns

A normalized and transformed copy of the input array.

transformValue()

template<typename T>

T CesiumGltf::transformValue	(	const T &	value,
		const std::optional< T > &	offset,
		const std::optional< T > &	scale )

Transforms the value by optional offset and scale factors.

Parameters

value	The value to transform.
offset	The amount to offset the value by, or std::nullopt to apply no offset.
scale	The amount to scale the value by, or std::nullopt to apply no scale. See applyScale.

validateArrayPropertyType()

template<typename T>

PropertyViewStatusType CesiumGltf::validateArrayPropertyType	(	const ClassProperty &	classProperty,
		const CesiumGltf::Enum *	pEnumDefinition = nullptr )

Validates a ClassProperty representing an array of values, checking for any type mismatches.

Template Parameters

T	The array type of the PropertyView that was constructed for this ClassProperty.

Parameters

classProperty	The class property to validate.
pEnumDefinition	If the class property is an enum array, this should be the enum definition. If not, this should be nullptr.

Returns

A PropertyViewStatus value representing the error found while validating, or PropertyViewStatus::Valid if no errors were found.
