Visualization of 3D-laser-radar data has special challenges beyond those for conventional computer graphics for 3D scanners. Such challenges include sampling limitations, very large data sets, obscuring material, increased noise, and the need for rapid identification of interesting features. The course provides an introduction to 3D-laser-radar characteristics relevant to visualization. Several key 3D processing and visualization methods (e.g., jitter noise reduction, data classification, surface generation, point-cloud display-enhancement, selectable transparency, and rapid display of large data sets) will be discussed.
