  1. Hi Fien - We have done some work to clean up the code a bit, so hopefully it will be more clear in the next version. The first one is a UUID for a label - I'm not sure of the context here. We do use UUID's throughout the system, and if you have them for certain things, like people and subjects, you can supply the ones you have, or the system will mint one for you. The second one I'm not sure, but it might be embedded binary for something like an image or a document (I mean an image of a setup - not the actual images that are part of your project). We have decided to handle this as separate files - so we will export them from the database and include them in the archive package that we will be producing - rather than having the binary inside the RDF. This was the behavior for the Beta though. Thanks for trying out the tools, and for your feedback! Carla
  2. hmm - I just downloaded and opened it just fine. It won't open when you click the link - but it should download. I'm using Acrobat and also tested it in preview on the Mac. Carla
  3. Tony - if you click on the tool/ configuration icon and click the button for "full size" that usually solves this particular problem. Sorry, I've been away from the forum a lot this summer - we'll just chalk it up to 2020 and leave it at that. Carla
  4. Wow - I think my notifications were somehow turned off - because I didn't get email about this message. And I so apologize for leaving you hanging. This is not a bug - and we are making this much simpler with the next version (I was just testing new software today) Essentially the issue is that in the Beta version you can only produce RDF for a group of image sets for Photogrammetry and for a single image set for RTI. We know this is confusing, so this is how we are fixing it: The idea is that you want to create RDF and Submission Information Packages (SIPs - new in the next version) for all of the images needed to produce a digital representation. So we are getting rid of the "groups" and instead introducing the concept of "Image Bundles." An Image bundle can be single set or multi set, depending on the technology. RTI is single set and photogrammetry is multi-set. Note that you can have a single image set in a photogrammetry image bundle - though you are allowed to have more. In RTI you can only have a single image set. It's at this image bundle level that it makes sense to do archiving and to export the metadata. We will also be providing reports for the Image bundle Bottom line is that in the Beta you have to export RDF from the group level for photogrammetry and from the image set level for RTI. This will be much cleaner in the new version, and we've integrated Inspector into the tools as well. We have massively redesigned the interface, and we are making it easier to add new "things" like people, stakeholders, etc - right when you want to use them. And lots of other updates too. It's a very active project right now. I think you will like the new tools. We will have scripts to update your database to support the new tools, since the data model has been changed to support the new features. So stay tuned - we hope to do a second Beta this fall. Carla
  5. Whoops - sorry for the delayed response. This summer has been a bit nutty - enough said. Do you get an error message, or does it just fail to detect the highlights? What platform (Mac or windows) you can also look in the .xml project log file that is created. That sometimes contains additional information about how far the process got and what might have failed. Carla
  6. Sorry, I'm a bit late to the party here - just catching up on posts, and I missed this before. In addition to the above suggestions, If you can see the whole surface you want to measure in one orthographic view - then you can make an orthomosaic and measure that. That is measuring along the surface, rather than point to point in a straight line. It doesn't work for everything, but for some situations it's a simple easy solution. Carla
  7. 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
  8. Hmm - I have it working on Windows 10 - just a regular install from our download in winter 2019. I haven't tried it recently. So sorry about all the problems. Carla
  9. Thanks Hembo! Turns out that RTiViewer won't run on Catalina either. Gianpaolo Palma from the Visual Computing Lab in Pisa is looking into recompiling it for 64 bit. He thinks it will be straight forward if we lose the functionality for the network viewing. That was really just an experiment in the current version, and I think there are better options for folks now - so losing that feature to get 64 bit seems like something we can live with. 2 different people are looking into 64 bit PTMFitter and HSHFitter. PTMFitter isn't open source, and we don't have the code. We do have the code for HSHFitter. Are the fitters the problem - or can you not run the RTiBuilder application? Please post any specific error messages you receive. Thanks - and I've just pinged the folks that were working on all these things to try to get an update. I'll let you know if there is a way for you to get involved. I appreciate the offer. Carla
  10. The first question is what platform are you on? If you are on Mac make sure that you install RTIBuilder somewhere on your system (i.e. drag it from the disk image (.dmg file) onto your hard drive) Most folks put it in Applications. If you run it from the disk image you can have problems like this. If this isn't the problem for you, then give a bit more info about your setup to help us figure it out. Carla
  11. HSHfitter was compiled as a 32 bit app on the Mac - and those aren't supported in Catalina. Someone is working on trying to solve this for the PTMFitter. The PTMFitter is turning out to be more work than initially thought, due to dependencies in the code. Note that it is NOT open source, and CHI does not have the code for it. I've asked someone to do this for HSHFitter - and I'll post when I have an answer as to whether they can do it, and when. We do have the code for HSHFitter and it is available under the GNU General Public License v3. Sorry for all the issues with this old software. Carla
  12. Thanks for jumping in Dave - I just checked it also - and it is downloading fine for me. I think your idea about it being quarantined by virus software makes the most sense. Carla
  13. I understand that PTMFitter is 32 bit, and therefore will not run in Catalina until we can create a 64bit version. We have had some discussions about that with various folks, because (as noted above) the PTMFitter is not open source code, and we at CHI do not have the code. We think we may have a solution - but I don't want to say for sure until we are sure. I just want to let you know that we have contacted folks who may be able to solve it. However, I'm not sure why RTIBuilder - which is a Java Application would not run, nor why HSHFitter wouldn't run. I just used the Go64 app and it says that the HSHFitter is also 32 bit. We do have the code for that one, so it should be easier to fix. I didn't get any warnings about RTIViewer. I have an older Mac and not running the latest OS. If anyone has tried ay of the tools on Catalina - please post what you have found about RTiViewer and RTiBuilder - other than the fitters, which we know are a problem. Carla
  14. Thanks for posting the RTI-dome.com - We're not familiar with them. It appears to be a small dome for insects and other very small subjects. Carla
  15. There are a lot of 32bit apps stil in use out there. Here's a quote from an article in Time magazine this week about how to check to see what 32bit apps you have on your system: "... if you’re dependent on a particular 32-bit app, it won’t work in macOS Catalina, as many Twitter users discovered after upgrading. Meanwhile, some popular apps, like Adobe Photoshop, appear to be suffering from temporary compatibility issues with Catalina, so it’s best to hold off on upgrading until a software patch resolves those problems. Want to see which of your apps are still 32-bit? On your Mac, hit the Apple menu, select About This Mac, and click System Report. In System Report, scroll down to Legacy Software, and take a look at all your 32-bit apps." Here's the full article: https://time.com/5696302/macos-catalina-upgrade/ I know this doesn't resolve the problem if RTI software no longer running - but I did want to point out that folks might want to be cautious about upgrading until they see the full impact - not just RTI software.
