    Hi Tom, Let me address a few things about the RTI software. First - both the RTIBuilder (with HSHFitter) and RTIViewer software are open source available upon request from us and under a GNU General Public License v3. This is noted in the software and the download page - and you only need to send email to info@c-h-i.org to receive it. We get 10-20 requests for the source code per year. Next - we are aware of the issues with the latest MacOS - Catalina and the requirement for 64bit software. We had some volunteer efforts underway to address this, which were set back with the insanity that 2020 has become. Just this week I received a test version of the HSHFitter that is 64 bit. If you want to test it, let me know. We'll release it once we've tried it out a bit. The PTMFitter is a bit trickier, because it's proprietary from HP, and none of the original folks who worked on it are there any more. We are working on a solution there, but it will take a bit longer. There is also a test version of 64bit RTIViewer for Mac - and it works fine for me (though I'm not running Catalina) and the person who tried it on Catalina couldn't get it to run. If you want to try that, again, let me know. Bottom line is that we do care about this software and know there are issues, but haven't had funding for software updates. We've put a small budget in a recent grant proposal that, if funded, should at least be able to get all the current software updated and running on the latest OS's and repackaged to get rid of the virus warning. We won't know until December if we will receive that funding. In the meantime, we hope to release these smaller pieces. There are a number of research labs working in this space. I don't know about the specific art scanner you link to, though Szymon Rusnkiewicz and team at Princeton have been doing similar things with modified flatbed scanners since 2007 - and have published some papers in this area such as this one: "A System for High-Volume Acquisition and Matching of Fresco Fragments: Reassembling Theran Wall Paintings" (with Benedict Brown, Corey Toler-Franklin, Diego Nehab, Michael Burns, David Dobkin, Andreas Vlachopoulos, Christos Doumas, and Tim Weyrich), ACM Transactions on Graphics (Proc. SIGGRAPH), 2008. We are interested in working to incorporate some of the most recent research in this area into usable tools for this community - and would like to do a proposal later this year to see if we can get it funded. We'll keep you posted if that happens. Thanks for your interest! Carla

    David, Those modes are available if you generate via PTM rather than HSH. Dave (IOMNHAS)

    I managed to find an old Mac running macOS 10.13 High Sierra and get a working RTI setup. It wasn't trouble-free to get it working, so I posted instructions on how to get everything working on an old system here: Hope this helps some people in the interim.

    I'm having to rebuild my RTI/PTM workflow on account of reinstalls etc. I know that none of the apps work on a macOS 64 bit system like 10.15 Mojave but I was lucky enough to find an old MacBook Air running macOS 10.13 High Sierra. Some of the links above are broken now, so here's a summary of what I did to get working RTI/PTM software in macOS 10.13 if you are lucky enough to have an old Mac hanging around. There are risks in allowing apps from being installed from anywhere, so bear this in mind if you are installing software from other places. Download RTIbuilder and add to the Applications folder as usual. It will not run, and macOS will report the app as broken. Disable Gatekeeper (this is what prevents the app from running) by opening a terminal and typing (or copy/paste) sudo spctl --master-disable Verify that this has worked by going into System Preferences > Security & Privacy and in the General tab check that there are now three options for installing software under "Allow downloaded apps from:" and that "Anywhere" is selected. Now you should be able to run RTIBuilder. If you're concerned about security, after you have finished building and viewing HSH RTIs, set the option in Security & Privacy back to another option such as "App Store and identified developers". If you want to create PTM files too: Right-click on RTIBuilder and select "Show Package Contents" then navigate into Contents > Resources > Java > Fitters > PTMfitter The folder will be empty. Keep it open and open a new Finder window/tab. Download the PTMfitter software from Carla's Dropbox link: https://www.dropbox.com/sh/jfsy0lhxu6zv4i4/AADJpq6E_GJmNw_s5C8r94CVa?dl=0 Extract the zip file and copy the file PTMfitter file (there's no file extension and this doesn't matter) into the PTMfitter directory that you still have open. Open a terminal and (assuming RTIBuilder is in your Applications folder) type/copy/paste cd /Applications/RTIbuilder-v2.0.2.app/Contents/Resources/Java/Fitters/PTMfitter Next, you need to make the PTMfitter file executable by typing chmod 755 PTMfitter Now you can close your Finder windows and launch RTIBuilder. It should now launch and be able to create both HSH/RTI and PTM files. I hope this helps some people at least. Thanks, Tom Curatorial Research Centre https://curatorialresearch.com (These instructions worked on macOS 10.13 High Sierra in February 2020)
