Engineering Principles Involved Geomatics Engineering Acquisition, processing, analysis, display and management of spatial information. Software Engineering Modularity (“Divide & conquer”) Generality
Design Progress What has been done Data collection: ILRIS-3D Interpolation: Plane fitting
Design Progress Difficulties Encountered Surface Interpolation Long run-time Long run-time Unreliable results Unreliable results
Software Development Code being developed in 3 programming languages: C, C++, C# Using Dynamic Link Libraries to integrate them all
Graphical User Interface Specification changed from OpenGL development to Managed DirectX Faster, more powerful, less restrictions Difficulties with active event registration, viewport technologies GUI developed in C#
