....measure, for example. This is very inefficient and time consuming because there may be inaccessible features, and the user must switch from indoors to outdoors at each iteration to modify the model and then verify its accuracy. Faster methods such as laser scanning and synthetic aperture radar [19], or multiple cameras [4] can be used to recover models, but tend to have large quantities (sometimes millions) of wasteful facets, and suffer from some features not being captured by the scans, causing shadows . We propose our novel CSG primitive based approach as a way of interactively ....

....of two handed interaction techniques. The system tends to focus on working on a direct ratio, rather than action at a distance techniques. Other automated capture techniques In the construction and surveying domain, a number of techniques are used to capture the geometry of outdoor objects [16]. In many cases, CAD drawings of buildings are already available, however for use in AR applications there may be a number of problems with these: Drawings may only be 2D floor plans, and immersive rendering requires full 3D models, preferably solid graphical models and not simple wire frames. ....
