The 3D visualization of luminous intensity distributions using the Techno Team 3D Viewer allows an analysis of the total measured distribution at a glance. LIDs are visualized three-dimensionally from any observer perspective. Photometric instabilities or sporadic disorders of the distribution, which are difficult to identify in the classical polar representation, occur in the 3D representation shows clearly visible. A variety of visualization options allows variable and user customized display as well as a synchronous observer point to the current visual comparison of several LIDs.
