We present an online method for filling holes in point clouds by exploiting the regularity of urban areas. Sweeping a plane across the scene we compute periodicity, major planes, and occlusions. Extending rays from the laser that have been occluded gives a planar approximation for holes in facades. The periodicity of the architecture is used to vastly improve this approximation yielding facades that seem complete and natural. Both abstract and high resolution mesh data is constructed from the
