By the evolution of 3D scanning techniques, creating 3D
models of real world objects is getting much easier. Beyond the humansized
objects one can easily scan complete buildings, roads, squares, or
even towns and countries as well. The raw data that scanning technologies,
such that LIDARs or photogrammetry based applications can
provide are point clouds. The size of such a point cloud can be enormous,
with billions of points, and processing and converting it to another format
is very costly. Due to this it is important to efficiently visualise
large point clouds and make it possible to modify them. In this paper we
give a brief overview of point cloud visualisation techniques and describe
our system that provides tools to manipulate point clouds by selecting,
annotating, deleting, cleaning necessary parts of them.
