Pointsampler

Reducing the number of data points

To be able to create a more sparse graph, we can use the PointSampler to spatially reduce the number of nodes.

from opendgm.meshtools.points.points_sampler import PointsSampler

# Sample points at min distance 5
point_ids = PointsSampler.select_regular_points(vertices, 5)

In this visualization, we see the orignal nodes (16426) in gray, with the reduced nodes (594) in red.
