  3. Dear all I'm trying to create a 3th order HSH (16 variables) with RTIBuilder on my Mac. But every time when I execute the program I get a RTI file from the second order (9 variables) or even from the first order (4 variables), although the order is set on "3". Does anyone have an idea how I can solve this? Thanks in advance!
  4. Hi, I made an RTI file with RTI builder using the Highlight based fitter, but I cannot see it in the RTI Viewer. I used 35 images of 5472x3672p each. I've already tried with both rti file examples available at Ch site and the viewer opens them without any problem. I'm running both programs on a windows 10 pro, intel core i5 64 bit cpu machine. Please I ask if somebody can help me because I ran out of ideas how to fix this. I leave the file attached, just in case anyone want to try to open it. aaaa_5472.rti
  5. I was wondering if anyone here had any experience with how to use RTI's to make a to scale drawing of an object, particular drawings of artifacts that can be used in publications. Any advice or tips would be greatly appreciated!
  6. Sorry, i find that and all is OK!!. But, when i try to process my image I obtain the same error. What do you do in my case?
  7. 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
  8. I can´t find this C:\RTI\Fish_1000\Fish_test.xmlC:\RTI\Fish_1000\finished-files\ Fish_test_1000.rti
  9. Hello all I'm trying to get to understand the exported output (xml/rdf) from DLN Capture Context. There are some parts with messy code. <rdfs:label>urn:uuid:af85af98-9c77-4812-8c40-352f9e08e51c</rdfs:label> and <crm:P03_has_range_literal>/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRof Hh0aHBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/2wBDAQkJCQwLDBgNDRgyIRwh MjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjL/wAAR CABLADgDASIAAhEBAxE ... Does anyone have an idea how I can interpret these lines? Thanks in advance! Fien
  10. SpeiVerta, OK, I think may best not to try to climb Everest as first mountain! CHI have provided a sample set of images - which definitely work. If there is any problem, still doing this, there is no point going on to your relatively-massive pictures. Please forgive me if these duplicate what you know or have tried, but this is the simplest set of steps, could you try these as they definitely work. Please try these and let us know if you successfully make and view a basic HSH RTI as below. Dave On your PC, if you don’t already have one, make a folder RTI at the top level on your C: drive, and within that, make a folder Fish_1000 so you end up with C:\RTI\Fish_1000 Download the Fish_1000 set of example files from http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/ And then – somewhere else on your PC - expand the fish_fossil-data-set_1000.zip file. In the zip file, down one level, you will see a folder jpeg-exports Copy that folder and its contents into C:\RTI\Fish_1000 so you end up with C:\RTI\Fish_1000\jpeg-exports which will contain 36 photographs named fish_fossil_01.jpg through fish_fossil_36.jpg Start RTI Builder In the Project Name box, type Fish_test In the Operation Sequence block, click on the first option – Highlight based (HSH Fitter) Then click the [Start new project] button On the Image selection screen which opens with an initial blank list, click the [Open folder] button at the right-hand edge of the screen In the Windows selection box which pops-up, it usually seems to default browsing to ‘My Documents’. Click on the ‘Computer’ icon (fourth one down) in the left-hand bar Double-click on C: Double-click on the RTI folder Double-click on the Fish_1000 folder Then click [Open] (N.B. please don’t click on the ‘jpeg-exports’ folder) You should then see a pop-up ‘Loading images’ with a progress bar When all the images have loaded, you should then see 36 images in the selection pane after which you should be able to proceed with RTI processing; and as you proceed with building your RTI model, you should see an xml and other folders appear in the project folder, so eventually, if you just proceed (using default options and not cropping) you will have: C:\RTI\Fish_1000\assembly-files C:\RTI\Fish_1000\finished-files C:\RTI\Fish_1000\jpeg-exports C:\RTI\Fish_1000\Fish_test.xml and your finished RTI will be C:\RTI\Fish_1000\finished-files\ Fish_test_1000.rti You will then have an HSH RTI which you should try to open with the viewer C:\RTI\Fish_1000\finished-files\ Fish_test_1000.rti
  11. Thank you for your fast answer 1) Did this work before for these exact images and just stop now? No, since i try to do the RTI i find error 2) Is this the first time you tried to build an HSH RTI? Yes 3) Have you successfully made an HSH RTI for other images of your own? No 4) IF you made one OK before, if you go back to that set, does it still work? No, always I find the same error 5) Have you tried making an HSH RTI with the sample set of fish-fossil images you can download from the CHI website? I am trying to do RTI for a warrior stela 6) If you can make the fish-fossil OK, it may be your images or the memory demand are too big. How many images are you using? / what is their size in MB? I am using 61 images in JPEG (712 MB) 7) If you only process, say, eight of your images, does the same happen? Yes, and ''not detected Highlight'' 8) If you - just for testing - make a copy of your images with smaller resolution, say 1/4 size, does that work? No, i get ''Improper call....'' 9) Also, It is always useful to also report what operating system/version you are running?; also the source of your images? Windows 10. My images comes from Nikon (in .NEF)
  12. SpeiVerta, Apologies that I can only reply in English. I can see there is definitely a problem, the size - as read by the HSHfitter - is enormous. The height and width used by the HSH fitter should, with no re-size, be the same as the 'Actual size' (see attached screenshot). It may well be that your images are too big for that HSH fitter, there are other options if that is the case but some questions/suggestions that may help identify the problem: 1) Did this work before for these exact images and just stop now? 2) Is this the first time you tried to build an HSH RTI? 3) Have you successfully made an HSH RTI for other images of your own? 4) IF you made one OK before, if you go back to that set, does it still work? 5) Have you tried making an HSH RTI with the sample set of fish-fossil images you can download from the CHI website? 6) If you can make the fish-fossil OK, it may be your images or the memory demand are too big. How many images are you using? / what is their size in MB? 7) If you only process, say, eight of your images, does the same happen? 8) If you - just for testing - make a copy of your images with smaller resolution, say 1/4 size, does that work? 9) Also, It is always useful to also report what operating system/version you are running?; also the source of your images?

  13. Hello, I am new here. When I use RTIBuilder and put the images, then i get ''Highlight Denitions Not detected'', when I pass the last phase I have this error ''Improper call to JPEG library in state 200''. I have all my photos in JPG and i can't get the model to put this in RTIViewer. I checked all my photos and there are not have spaces in the names or folder. Is so important this job for my thesis. Sorry for my english, I speak spanish Thank you so much!
  14. 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
  15. 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
  16. 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
  17. 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
  18. 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
  19. 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
  20. I recently came across some interesting relief models being shown on Reddit. The results looked a lot like RTI/PTM to me, and the poster claimed to offer a commercial scanner that produces similar results to our domes. It's called ArtScanner: https://www.paflab.art/en/activity/artscanner/432 I thought that forum members might be interested to know about this development. This leads me to wonder what the future of RTI might be, and if there are any new developments underway? Us Mac users can't build RTI files any more, and there doesn't seem to be any source code on the CHI website or on GitHub. Perhaps a public repository could help to generate new interest in this amazing technology?
  21. Yes: MSII (Multi-Scale Integral Invariants) provides four different curvature measures i.e. how bent the surface is. This shown in our latest video for the more prominent curvatre: https://youtu.be/W9U6hT96l5E .... this one is related to Gaussian curvature. The other three measures you can compute on the commandline with "gigamesh-featurevectors" and "gigamesh-featurevectors-sl", which has only the radius as a parameter. Furthermore you can compute distances to spheres, cones and cylinders, which are used in GigaMesh to compute unwrappings/rollouts.
  22. Using RTIBuilder, all the jpegs adjusted and imported, HSH Fitter option chosen, detect spheres done, but highlight detection fails, any ideas why?
  23. Thank you Dave, I did wonder. Now for another try. David
  24. David, Those modes are available if you generate via PTM rather than HSH. Dave (IOMNHAS)
  25. The Rendering Mode options offered for my project are Default, Specular Enhancement and Normals Visualization. The RTIViewer Guide says that only those modes that can be applied to the current image are offered. My images were generated as RTI files as per the Guide, via HSHfitter. What are the requirements for images to enable the other Rendering Modes, in particular Multilight Enhancement?
  26. Take a look at Gigamesh. https://gigamesh.eu/?page=home
  27. Mike, Just some more info to back your report up and maybe shed a little light for the developers: I've just tried this on my installation - with both CHI supplied test data and my own data. I had never tried for a PG set before, I get exactly the same as you. BUT if I highlight an RTI image set, it will allow me to export an RDF. Dave
