Member Function Documentation

◆ Clear()

PointCloudPicker & open3d::visualization::PointCloudPicker::Clear ( )

overridevirtual

Clear all elements in the geometry.

Implements open3d::geometry::Geometry3D.

◆ GetAxisAlignedBoundingBox()

geometry::AxisAlignedBoundingBox open3d::visualization::PointCloudPicker::GetAxisAlignedBoundingBox ( ) const

finalvirtual

If point cloud does not exist, creates an axis-aligned bounding box form its default constructor. If point cloud exists, creates the axis-aligned bounding box around it. Further details in AxisAlignedBoundingBox::CreateFromPoints()

Implements open3d::geometry::Geometry3D.

◆ GetCenter()

Eigen::Vector3d open3d::visualization::PointCloudPicker::GetCenter ( ) const

finalvirtual

Returns the center of the geometry coordinates.

Implements open3d::geometry::Geometry3D.

◆ GetMaxBound()

Eigen::Vector3d open3d::visualization::PointCloudPicker::GetMaxBound ( ) const

finalvirtual

Returns max bounds for geometry coordinates.

Implements open3d::geometry::Geometry3D.

◆ GetMinBound()

Eigen::Vector3d open3d::visualization::PointCloudPicker::GetMinBound ( ) const

finalvirtual

Returns min bounds for geometry coordinates.

Implements open3d::geometry::Geometry3D.

◆ GetMinimalOrientedBoundingBox()

geometry::OrientedBoundingBox open3d::visualization::PointCloudPicker::GetMinimalOrientedBoundingBox ( bool robust = false ) const

finalvirtual

If point cloud does not exist, creates an oriented bounding box form its default constructor. If point cloud exists, creates the minimal oriented bounding box around it. Further details in OrientedBoundingBox::CreateFromPointsMinimal()

Parameters

robust If set to true uses a more robust method which works in degenerate cases but introduces noise to the points coordinates.

Implements open3d::geometry::Geometry3D.

◆ GetOrientedBoundingBox()

geometry::OrientedBoundingBox open3d::visualization::PointCloudPicker::GetOrientedBoundingBox ( bool robust = false ) const

finalvirtual

If point cloud does not exist, creates an oriented bounding box form its default constructor. If point cloud exists, creates the oriented bounding box around it. Further details in OrientedBoundingBox::CreateFromPoints()

Parameters

robust If set to true uses a more robust method which works in degenerate cases but introduces noise to the points coordinates.

Implements open3d::geometry::Geometry3D.

◆ IsEmpty()

bool open3d::visualization::PointCloudPicker::IsEmpty ( ) const

overridevirtual

Returns true iff the geometry is empty.

Implements open3d::geometry::Geometry3D.

◆ Rotate()

PointCloudPicker & open3d::visualization::PointCloudPicker::Rotate	(	const Eigen::Matrix3d &	R,
		const Eigen::Vector3d &	center
	)

overridevirtual

Apply rotation to the geometry coordinates and normals. Given a rotation matrix \(R\), and center \(c\), a given point \(p\) is transformed according to \(R (p - c) + c\).

Parameters

R	A 3x3 rotation matrix
center	Rotation center that is used for the rotation.

Implements open3d::geometry::Geometry3D.

◆ Scale()

PointCloudPicker & open3d::visualization::PointCloudPicker::Scale	(	const double	scale,
		const Eigen::Vector3d &	center
	)

overridevirtual

Apply scaling to the geometry coordinates. Given a scaling factor \(s\), and center \(c\), a given point \(p\) is transformed according to \(s (p - c) + c\).

Parameters

scale	The scale parameter that is multiplied to the points/vertices of the geometry.
center	Scale center that is used to resize the geometry.

Implements open3d::geometry::Geometry3D.

◆ SetPointCloud()

bool open3d::visualization::PointCloudPicker::SetPointCloud ( std::shared_ptr< const geometry::Geometry > ptr )

◆ Transform()

PointCloudPicker & open3d::visualization::PointCloudPicker::Transform ( const Eigen::Matrix4d & transformation )

overridevirtual

Apply transformation (4x4 matrix) to the geometry coordinates.

Implements open3d::geometry::Geometry3D.

◆ Translate()

PointCloudPicker & open3d::visualization::PointCloudPicker::Translate	(	const Eigen::Vector3d &	translation,
		bool	relative = `true`
	)

overridevirtual

Apply translation to the geometry coordinates.

Parameters

translation	A 3D vector to transform the geometry.
relative	If `true`, the `translation` is directly applied to the geometry. Otherwise, the geometry center is moved to the `translation`.

Implements open3d::geometry::Geometry3D.
