root_node

root_node是open3d.geometry.Octree类的一个成员函数。它返回最上层的八叉树结点。

语法

root = octree.root_node

参数

无

返回值

返回值是一个open3d.geometry.OctreeInternalNode

异常

无异常抛出。

示例

import open3d as o3d
import numpy as np

points = np.random.rand(10000, 3)
octree = o3d.geometry.Octree(max_depth=5, leaf_size=10)
octree.convert_from_point_cloud(o3d.geometry.PointCloud(points))

root = octree.root_node

print(root)

输出：

OctreeInternalNode[Children=[OctreeInternalNode[Children=[OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]], OctreeInternalNode[Children=[OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]], OctreeInternalNode[Children=[OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]], OctreeInternalNode[Children=[OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]], OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeInternalNode[Children=[OctreeNode], OctreeNode, OctreeNode, OctreeNode]]]]]

备注

root_node是open3d库中用于构建八叉树的基础方法，它返回整个八叉树的最高级结点。我们可以通过遍历结点来获取八叉树中的所有结点，并实现一些高效的数据查询和分析操作。
