With advanced technologies, experiments and data analyses are often performed on a computer interface. When accidents or natural disasters occur, engineers analyze the damage to prevent future failure. In a similar fashion when engineers perform experiments they may deal with complex components or environments. What both of these situations have in common is they contain objects or environments too complex to reproduce in a computer-aided design (CAD) model. With a 3D scanner the surveyor is able to scan the desired object or location and export the data into a workable format. The Riegl 3D scanner operates by emitting a laser beam while it rotates a specified amount of degrees. Once the laser beam hits an object it bounces back to the scanner. The scanner then calculates the distance of the object by the time it takes for the laser beam to return to the scanner. The scanner sends all data to the accompanying computer program which outputs a point cloud image which can be exported into many different formats. This STAR research project focuses on the data retrieved form the sensor. With this data multiple plots where generating showing a virtual image of the surrounding environment. 98
