Parameters:

pointsnp.ndarray, optional

3D point coordinates.

quaternionsnp.ndarray, optional

Orientation quaternions for each point (scalar first w,x,y,z).

colortuple, optional

Base RGB color values, by default (0.7, 0.7, 0.7).

sampling_ratenp.ndarray, optional

Sampling rates along each axis.

metadict, optional

Metadata dictionary.

vtk_actorvtk.vtkActor, optional

Custom VTK actor object.

vertex_propertiesVertexPropertyContainer, optional

Additional vertex properties.

**kwargs

Additional keyword arguments including normals.

__init__(points=None, quaternions=None, color=(0.7, 0.7, 0.7), sampling_rate=None, meta=None, vtk_actor=None, vertex_properties=None, **kwargs)

Methods

__init__([points, quaternions, color, ...])
change_representation([representation])	Change the visual representation mode of the geometry.
color_points(point_ids, color)	Color specific points in the geometry using set_scalars backend.
compute_distance(query_points[, k])
get_number_of_points()	Get total number of points in the geometry.
merge(geometries)	Merge multiple geometry objects into a single geometry.
set_appearance([size, opacity, ...])	Set visual appearance properties of the geometry.
set_color([color])	Set uniform color for all points in the geometry.
set_scalars(scalars, color_lut[, ...])	Set scalar data for coloring points.
set_visibility([visibility])	Set geometry visibility in the scene.
swap_data(points[, normals, faces, ...])	Replace geometry data with new point cloud or mesh data.
