EigenMatrixToTensor()

template<class T , int M, int N, int A>

core::Tensor open3d::core::eigen_converter::EigenMatrixToTensor

(

const Eigen::Matrix< T, M, N, A > &

matrix

)

Converts a Eigen matrix of shape (M, N) with alignment A and type T to a Tensor.

Parameters

matrix

A templated Eigen matrix.

Returns

A tensor converted from the eigen matrix.

EigenVector3dVectorToTensor()

core::Tensor open3d::core::eigen_converter::EigenVector3dVectorToTensor	(	const std::vector< Eigen::Vector3d > &	values,
		core::Dtype	dtype,
		const core::Device &	device
	)

Converts a vector of Eigen::Vector3d to a (N, 3) tensor. This function also takes care of dtype conversion and device transfer if necessary.

Parameters

values	A vector of Eigen::Vector3d values, e.g. a list of 3D points.
dtype	Dtype of the output tensor.
device	Device of the output tensor.

Returns

A tensor of shape (N, 3) with the specified dtype and device.

EigenVector3iVectorToTensor()

core::Tensor open3d::core::eigen_converter::EigenVector3iVectorToTensor	(	const std::vector< Eigen::Vector3i > &	values,
		core::Dtype	dtype,
		const core::Device &	device
	)

Converts a vector of Eigen::Vector3i to a (N, 3) tensor. This function also takes care of dtype conversion and device transfer if necessary.

Parameters

values	A vector of Eigen::Vector3i values, e.g. a list of 3D points.
dtype	Dtype of the output tensor.
device	Device of the output tensor.

Returns

A tensor of shape (N, 3) with the specified dtype and device.

TensorToEigenVector3dVector()

std::vector< Eigen::Vector3d > open3d::core::eigen_converter::TensorToEigenVector3dVector

(

const core::Tensor &

tensor

)

Converts a tensor of shape (N, 3) to std::vector<Eigen::Vector3d>. An exception will be thrown if the tensor shape is not (N, 3). Regardless of the tensor dtype, the output will be converted to to double.

Parameters

tensor

A tensor of shape (N, 3).

Returns

A vector of N Eigen::Vector3d values.

TensorToEigenVector3iVector()

std::vector< Eigen::Vector3i > open3d::core::eigen_converter::TensorToEigenVector3iVector

(

const core::Tensor &

tensor

)

Converts a tensor of shape (N, 3) to std::vector<Eigen::Vector3i>. An exception will be thrown if the tensor shape is not (N, 3). Regardless of the tensor dtype, the output will be converted to to double.

Parameters

tensor

A tensor of shape (N, 3).

Returns

A vector of N Eigen::Vector3i values.
