New Features in the 1.1 Release
- Numeric parameter values
All parameters, including the rendering parameter values and the values for an RTI view’s pan position and lighting angle, are now displayed with specific numeric controls as well as sliders, so that you can describe, share, and reproduce specific views accurately.
- Snapshot data record
When you create a snapshot image of the current view, the specific numeric parameter values that were applied to the original RTI file to create the snapshot image are saved to a sidecar XML file; that is, an XML file with the same base name as the RTI file.
The entire set of parameters that describes a view, including the pan position, lighting angle, and all rendering values, can now be saved as a named view called a bookmark. You can create multiple bookmarks for a single RTI file, and you can associate any number of notes with a bookmark. You can reload a saved bookmark to recreate a specific view. You can edit a new or saved view. If you edit a bookmarked view, you can re-save the bookmark with the new values, or save the edited view as a new bookmark to create variations of a given view. See “Bookmarking views” in the RTIViewer User Guide 1.1 for more information.
- Normals visualization viewing mode
The Normals Visualization viewing mode creates a false-color view of the subject of an RTI that makes it possible to visualize the normals information that describes the surface contours and orientation. See “Normals Visualization mode” in the RTIViewer User Guide 1.1 for an example.
Note: Please see the RTIViewer User Guide for more complete acknowledgments.
This tool, designed for cultural heritage and natural science application, was primarily developed by the Italian National Research Council's (CNR) Institute for Information Science and Technology's (ISTI) Visual Computing Laboratory (http://vcg.isti.cnr.it). The work was financed by Cultural Heritage Imaging with majority funding from the US Institute of Museum and Library Services' (IMLS) and National Leadership Grant Program (award number LG-25-06-010706). RTIViewer also contains significant software and design contributions from the University of California at Santa Cruz; the Universities do Minho in Portugal; Tom Malzbender, formerly of HP Labs; and Cultural Heritage Imaging.
The updated 1.1 version of the RTIViewer software and User Guide was partially funded by a 21st Century Museum Professionals grant from the IMLS, along with volunter efforts and private contributions. The Bookmarks feature added in the 1.1 release is based on work done by Leif Isaksen of the University of Southampton, UK. We would especially like to acknowledge the work of Ronald Bourret and Gianpaolo Palma for the development work for this release.
