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.

Illumination Map
- IMAP setup
- Fixed problems setting registration direction type.
- Fixed error when selecting template IMG with no target horizons.
- Remember last used mapping domain when opening the setup dialog the second time.
- Warning if IMG setup will lead to high memory consumption in generation.
- IMAP generation
- Prevent crash of Illumination Map module if the generation process crashes.
- Fixed problems on S-velocity projection. Normalization of slowness vector.
- Improved stability and minor improvements.
FlowerPlot

NORSAR-3D 5.4.4 (March 25, 2011)
Version 5.4.4 contains important stability improvements for the Illumination Map Batch.
Model Builder
- Improved handling of very small interfaces when a model is stored.
- Using less memory in some cases when a model is loaded.

Model Builder
- New functionality to draw a polygon on an interface, and smooth the part that is inside.
- New functionality to draw a polygon on an interface, and remove the vertices that are inside/outside.
- During interactive block/horizon definition, a red marker indicates when cursor position can be used.
- During interactive block/horizon definition, lines are drawn between the interfaces that belong to the block/horizon that is currently defined.
- Interface intersection menus are put in a single menu for faster response if user cancels the process.

- Removed flip of the positive direction of the interface normal within an interface, which could appear in some rare cases.
Illumination Map
- Fixed issue that default color maps were not available in the function rendering dialog, and that color functions could not be found.
- Fixed issue that Trimesh IMGs could not be created in IMG setup.
- Fixed issue that if there are several ray codes in the selected event set, one is selected by default, which caused confusion. Now a dialog for selecting ray codes pops up.
Common Shot Wavefront Tracer
- Fixed issue that when "Event Attribute Storing Option" set to "Synthetic Seismogram" in Common Shot Wavefront Tracer, the "Ray Normal Vector at Receiver" wasn't stored, which is necessary if the "Chosen Direction" is selected by the Seismogram Generator.
Flower Plot
- Fixed issue that generation failed when another ray code than dirP or dirS was selected.
