◆ 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.
