Detailed Description

template<class T = double>
class rw::math::EAA< T >

A class for representing an equivalent angle-axis rotation.

This class defines an equivalent-axis-angle orientation vector also known as an \( \thetak \) vector or "axis+angle" vector

The equivalent-axis-angle vector is the product of a unit vector \( \hat{\mathbf{k}} \) and an angle of rotation around that axis \( \theta \)

Note: given two EAA vectors \( \theta_1\mathbf{\hat{k}}_1 \) and \( \theta_2\mathbf{\hat{k}}_2 \) it is generally not possible to subtract or add these vectors, except for the special case when \( \mathbf{\hat{k}}_1 == \mathbf{\hat{k}}_2 \) this is why this class does not have any subtraction or addition operators

lhs	[in] first Vector
rhs	[in] second vector.

Returns: True if a equals b, false otherwise.

◆ read() [1/2]

void read	(	rw::math::EAA< double > &	sobject,
		rw::common::InputArchive &	iarchive,
		const std::string &	id
	)

Parameters

sobject	[out] the object in which the data should be streamed into
iarchive	[in] the InputArchive from which to read data.
id	[in] The id of the serialized sobject.

Note: the id can be empty in which case the overloaded method should provide a default identifier. E.g. the Vector3D class defined "Vector3D" as its default id.

◆ read() [2/2]

void read	(	rw::math::EAA< float > &	sobject,
		rw::common::InputArchive &	iarchive,
		const std::string &	id
	)

Parameters

sobject	[out] the object in which the data should be streamed into
iarchive	[in] the InputArchive from which to read data.
id	[in] The id of the serialized sobject.

Note: the id can be empty in which case the overloaded method should provide a default identifier. E.g. the Vector3D class defined "Vector3D" as its default id.

◆ write() [1/2]

void write	(	const rw::math::EAA< double > &	sobject,
		rw::common::OutputArchive &	oarchive,
		const std::string &	id
	)

Parameters

sobject	[in] the object from which the data should be streamed.
oarchive	[out] the OutputArchive in which data should be written.
id	[in] The id of the serialized sobject.

Note: the id can be empty in which case the overloaded method should provide a default identifier. E.g. the Vector3D class defined "Vector3D" as its default id.

◆ write() [2/2]

void write	(	const rw::math::EAA< float > &	sobject,
		rw::common::OutputArchive &	oarchive,
		const std::string &	id
	)

Parameters

sobject	[in] the object from which the data should be streamed.
oarchive	[out] the OutputArchive in which data should be written.
id	[in] The id of the serialized sobject.

Note: the id can be empty in which case the overloaded method should provide a default identifier. E.g. the Vector3D class defined "Vector3D" as its default id.
