Detailed Description

Octree pointcloud point vector class

Note:
This pointcloud octree class generate an octrees from a point cloud (zero-copy). Every leaf node contains a list of point indices of the dataset given by setInputCloud.
The octree pointcloud is initialized with its voxel resolution. Its bounding box is automatically adjusted or can be predefined.
