Detailed Description

template<typename PointT, typename LeafContainerT = OctreePointCloudAdjacencyContainer<PointT>, typename BranchContainerT = OctreeContainerEmpty>
class pcl::octree::OctreePointCloudAdjacency< PointT, LeafContainerT, BranchContainerT >

Octree pointcloud voxel class which maintains adjacency information for its voxels.

This pointcloud octree class generates an octree from a point cloud (zero-copy). The octree pointcloud is initialized with its voxel resolution. Its bounding box is automatically adjusted or can be predefined.

The OctreePointCloudAdjacencyContainer class can be used to store data in leaf nodes.

An optional transform function can be provided which changes how the voxel grid is computed - this can be used to, for example, make voxel bins larger as they increase in distance from the origin (camera).

Note
See SupervoxelClustering for an example of how to provide a transform function.
