NORSAR-3D 5.5 (May 11, 2012)
Version 5.5 introduces new tools for survey planning and illumination studies based on Illumination Ray (IRAY) concept. In addition a new fully integrated 3D viewer with the ability to plot all data objects in a NORSAR project is introduced. The viewer is the first step to bring NORSAR-3D into the new NORSAR Seismic Modelling platform. This framework is already used for SeisRoX. Included in the release are also major improvements in the Model Builder: The ability to make a 3D model from a set of 2D lines, and a more robust handling of interface intersection. Other modules are also improved, see below.
