Aims• To develop a 3D model of the Mont Terri anticline• To describe the necessary steps in a “cook-book”• To present the 3D model as movie & VRML-scene• Side-effect
• To check the consistency of 2D profiles
Methodology• Using maps, measurements etc. as input data• Deriving a “simplified model” of the tectonic setting• Iterative refinement of the model
Introduction – The Mont Terri model
