Detailed Description

OctreeInternalNode class, containing OctreeNode children.

Children node ordering conventions are as follows.

For illustration, assume,

• root_node: origin == (0, 0, 0), size == 2

Then,

• children_[0]: origin == (0, 0, 0), size == 1
• children_[1]: origin == (1, 0, 0), size == 1, along X-axis next to child 0
• children_[2]: origin == (0, 1, 0), size == 1, along Y-axis next to child 0
• children_[3]: origin == (1, 1, 0), size == 1, in X-Y plane
• children_[4]: origin == (0, 0, 1), size == 1, along Z-axis next to child 0
• children_[5]: origin == (1, 0, 1), size == 1, in X-Z plane
• children_[6]: origin == (0, 1, 1), size == 1, in Y-Z plane
• children_[7]: origin == (1, 1, 1), size == 1, furthest from child 0

Constructor & Destructor Documentation

OctreeInternalNode()

open3d::geometry::OctreeInternalNode::OctreeInternalNode ( )

inline

Default Constructor.

Member Function Documentation

ConvertFromJsonValue()

bool open3d::geometry::OctreeInternalNode::ConvertFromJsonValue ( const Json::Value &  value )

overridevirtual

Implements open3d::utility::IJsonConvertible.

Reimplemented in open3d::geometry::OctreeInternalPointNode.

ConvertToJsonValue()

bool open3d::geometry::OctreeInternalNode::ConvertToJsonValue ( Json::Value &  value ) const

overridevirtual

Implements open3d::utility::IJsonConvertible.

Reimplemented in open3d::geometry::OctreeInternalPointNode.

GetInitFunction()

std::function< std::shared_ptr< OctreeInternalNode >)> open3d::geometry::OctreeInternalNode::GetInitFunction ( )

static

Get lambda function for initializing OctreeInternalNode.

When the init function is called, an empty OctreeInternalNode is created.

GetInsertionNodeInfo()

std::shared_ptr< OctreeNodeInfo > open3d::geometry::OctreeInternalNode::GetInsertionNodeInfo ( const std::shared_ptr< OctreeNodeInfo > &  node_info, const Eigen::Vector3d &  point  )

static

GetUpdateFunction()

std::function< void(std::shared_ptr< OctreeInternalNode >)> open3d::geometry::OctreeInternalNode::GetUpdateFunction ( )

static

Get lambda function for updating OctreeInternalNode.

This update function does nothing.

std::vector<std::shared_ptr<OctreeNode> > open3d::geometry::OctreeInternalNode::children_

Use vector instead of C-array for Pybind11, otherwise, need to define more helper functions https://github.com/pybind/pybind11/issues/546#issuecomment-265707318 List of children Nodes.
