Open3Dのvisualizationで点数を減らして処理を軽くする

実際のところ

import open3d as o3d

pcds = []
pcds.append(o3d.io.read_point_cloud('/root/open3d_data/extract/LivingRoomPointClouds/cloud_bin_1.ply'))

downpcd = pcds[0].voxel_down_sample(voxel_size=0.05)

o3d.visualization.draw_plotly(
  [downpcd],
  width=400,
  height=400
)
