Abstract
This report describes the production of three graphics models of the Hercules CC130 aircraft processed from laser scan data for both the aircraft exterior and cockpit interior. These Polygon and Non- Uniform Rational B-Spline (NURBS) surface models are scalable, and logically arranged in groups and/or layers. They also represent graphically the range of motions in the cockpit of the seats and pedals. An external mean accuracy of less than 3 millimetres (mm), and standard error of 6-9 mm for modelled areas of interest were verified with respect to the original data. An interior mean accuracy of less than 1 mm and standard error of 2-3 mm for modelled areas of interest were similarly verified. This accuracy is consistent and compatible with the accuracy of the laser scanners and their data.
