About NeighborSearchMethod

[piluohong]

Afternoon,athours. thanks your good works.
enum class NeighborSearchMethod { DIRECT27, DIRECT7, DIRECT1, /* supported on only VGICP_CUDA */ DIRECT_RADIUS };

Is it these searching methods mean the differences of distribution to distribution ?

It specifies the method to find voxels corresponding to a point. To compute registration errors, DIRECT1 uses only the voxel where a point fell while DIRECT27 uses 3x3x3 voxels around it.
