Detailed Description

Dense point cloud object.

A dense point cloud is an ordered set of 3D points, placed on a grid with a given width and height. The advantage of dense clouds is to have immediate neighbor information. The disadvantage is, that you cannot have arbitrary clouds (e.g.an affine transformation breaks the lattice view). Also each x-y-position can have only one corresponding z-height.

A dense point cloud has grid / neighbor information available and has a larger memory than a sparse point cloud (due to NaN values / holes).

Each dense point cloud can be converted to a sparse point cloud.
