Process: RTIBuilder Download
RTIBuilder is a software interface to a set of tools that process your captured image set to produce the final RTI files. The RTIBuilder download includes the Hemispherical Harmonics (HSH) fitter to create
Note: If you want to create Polynomial Texture Maps (PTMs), you must download the PTM Fitter software from the Hewlett Packard web site. In the RTIBuilder user guide, which you can download below, you will find installation instructions, including how to set up the PTM Fitter software. When you open the guide, see the section entitled “Download the PTM Fitter plug-in.”
RTIBuilder is written in the Java programming language, and it requires that you have Java version 6 or higher installed on your computer.

The work was funded by Cultural Heritage Imaging and the Universidade do Minho. Cultural Heritage Imaging also provided software requirements, design advice, testing, general feedback, and documentation.
The 2.0.2 release of RTIBuilder includes the Hemispherical Harmonics (HSH) fitter. The HSHfitter was developed at the University of California, Santa Cruz, Computer Science Department in collaboration with Cultural Heritage Imaging, which provided funding for this work from the US Institute of Museum and Library Services (IMLS) National Leadership Grant Program (Award Number LG-25-06-010706). Tom Malzbender, formerly of Hewlett Packard Labs, also collaborated.
The Highlight RTI methodology was developed at Cultural Heritage Imaging by Mark Mudge, Marlin Lum and Carla Schroer with technical guidance from Tom Malzbender, formerly of Hewlett Packard Labs. The idea for Highlight RTI and its original execution came from a collaboration between Tom Malzbender, Mark Mudge, Marlin Lum, and Carla Schroer. Many others commented, tweaked, gave ideas and were generally helpful in the development of the capture methodology (described in detail in the guide Reflectance Transformation Imaging: Guide To Highlight Image Capture. It is impossible to name everyone who contributed, but we would especially like to acknowledge our Portuguese collaborators at the University of Minho: Alberto Proença, Luis Paulo Santos, and João Barbosa, as well as Professor James Davis at UC Santa Cruz.
