Abstract
Today's three-dimensional (3D) virtual environments
(VEs) are usually based on textured polygonal 3D
models, which represent the appearance and geometry
of the virtual world. However, some application
domains require other graphical paradigms, which are
currently not adequately addressed by 3D user
interfaces. We introduce a novel approach for a
technical human-robot telepresence setup that allows
a human observer to explore a VE, which is a 3D
reconstruction of the real world based on point
clouds. Such point cloud virtual environments
(PCVEs) represent the external environment, and are
usually acquired by 3D scanners. We present an
application scenario, in which a mobile robot
captures 3D scans of a terrestrial environment,
which are automatically registered to a coherent
PCVE. This virtual 3D reconstruction is displayed in
an immersive virtual environment (IVE) in which a
user can explore the PCVE. We explain and describe
the technical setup, which opens up new vistas of
presenting a VE as points rather than a polygonal
representation.
