Point3D represents a singular point in three-dimensional space with optional color, radii, and label. Point3D entities will be drawn as part of the 3D Spatial SpaceView.

It is compatible with AnnotationContext. class_id can be used to provide colors and labels from the annotation context, and keypoint_id can be used to make connected edges between points. See examples in the AnnotationContext documentation.

Full Example

"""Log some random points with color and radii.""" import rerun as rr from numpy.random import default_rng rr.init("rerun_example_points", spawn=True) rng = default_rng(12345) positions = rng.uniform(-5, 5, size=[10, 3]) colors = rng.uniform(0, 255, size=[10, 3]) radii = rng.uniform(0, 1, size=[10]) rr.log_points("random", positions=positions, colors=colors, radii=radii)
