is_empty(self)¶

Returns True iff the geometry is empty.

Returns: bool

rotate(self, rotation, center=True, type=RotationType.XYZ)¶

Apply rotation to the geometry coordinates and normals.

Parameters

rotation (numpy.ndarray[float64[3, 1]]) – A 3D vector that either defines the three angles for Euler rotation, or in the axis-angle representation the normalized vector defines the axis of rotation and the norm the angle around this axis.
center (bool, optional, default=True) – If true, then the rotation is applied to the centered geometry
type (open3d.geometry.RotationType, optional, default=RotationType.XYZ) – Type of rotation, i.e., an Euler format, or axis-angle.

Returns

open3d.geometry.Geometry3D

scale(self, scale, center=True)¶

Apply scaling to the geometry coordinates.

Parameters

scale (float) – The scale parameter that is multiplied to the points/vertices of the geometry
center (bool, optional, default=True) – If true, then the scale is applied to the centered geometry

Returns

open3d.geometry.Geometry3D

transform(self, arg0)¶

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

Parameters: arg0 (numpy.ndarray[float64[4, 4]]) –

translate(self, translation, relative=True)¶

Apply translation to the geometry coordinates.

Parameters

translation (numpy.ndarray[float64[3, 1]]) – A 3D vector to transform the geometry
relative (bool, optional, default=True) – If true, the translation vector is directly added to the geometry coordinates. Otherwise, the center is moved to the translation vector.
