Examples

Simple 2D points

"""Log some very simple points.""" import rerun as rr import rerun.blueprint as rrb rr.init("rerun_example_points2d", spawn=True) rr.log("points", rr.Points2D([[0, 0], [1, 1]])) # Set view bounds: rr.send_blueprint(rrb.Spatial2DView(visual_bounds=rrb.VisualBounds2D(x_range=[-1, 2], y_range=[-1, 2])))

Randomly distributed 2D points with varying color and radius

"""Log some random points with color and radii.""" import rerun as rr import rerun.blueprint as rrb from numpy.random import default_rng rr.init("rerun_example_points2d_random", spawn=True) rng = default_rng(12345) positions = rng.uniform(-3, 3, size=[10, 2]) colors = rng.uniform(0, 255, size=[10, 4]) radii = rng.uniform(0, 1, size=[10]) rr.log("random", rr.Points2D(positions, colors=colors, radii=radii)) # Set view bounds: rr.send_blueprint(rrb.Spatial2DView(visual_bounds=rrb.VisualBounds2D(x_range=[-4, 4], y_range=[-4, 4])))
