  2. Hello all, My Mac, unbeknownst to me was on Auto-update and I'm unwillingly on Mac OS Big Sur..Most apps work. RTI Builder comes up as 'damaged. I tried the usual fix, to open apps from "anywhere" but that hasn't worked as of yet. Has anyone else run into this? If so, is there a fix? Many Thanks to all,
  3. I'm having a similar problem with MacOS. I'm running MacOS Big Sur 11.1 and now I can't open RTI Viewer at all. When I try, I get an error that says: "RTIViewer.app" cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware." The manager now only gives me the option of moving the app to the trash or canceling my attempt to open it. As a follow up, I did enough looking around that I know I can control-click to open the app, select open, then I get an option to open the application. I still thought I might report the problem here.
  4. Interesting open-access article on ways to extract features from photogrammetry models: https://www.cambridge.org/core/journals/antiquity/article/3d-contour-detection-a-nonphotorealistic-rendering-method-for-the-analysis-of-egyptian-reliefs/3DF1102C5016098C8D14D203D9D41C7C
  5. It has taken me a long time to try out the beta DLN-CC and DLN-Inspector, but they look to be really promising tools to help organize projects and manage metadata. Some initial observations: The RTI Image Set Details tab titled "General" is currently set up for Highlight-RTIs. It would be helpful to have some fields in the "RTI Properties" section (or on the "Setup" tab, below) for dome-based RTI parameters, such as the radius of the dome (I used string length as a substitute, but it's not exactly the same geometry), the number of lights, etc. The "Setup" tab allows a single photo of the setup to be added, but this might include another section to place parameters for the geometry of the capture setup (which is currently in the "General" tab for "RTI Properties"). For our RTI dome geometry, such measurements could include the height of the stage on which objects are placed, the vertical distance between the stage and the plane of the equator of the dome, the distance between the camera sensor and the plane of the equator of the dome, the number and type of lights; etc. For dome-RTI capture setups, a way to point to LP files and other calibration files (e.g., flat-fields, color checker profiles) that are used for processing multiple image sets would be helpful. An easier way to define custom directory structures for image sets without manually entering details into JSON files would be useful, especially for legacy projects with existing directory structures that don't fit the examples in the user guides. These are just some suggestions that I'd find useful. I realize there's a balance between tracking all the details and keeping the DLN tools simple and easy to use for the majority of people using RTI and photogrammetry. Thanks for all your hard work on these DLN tools! Best wishes, Taylor
  6. Hi Carla, I've set up a project, image set group, and a single RTI image set for initial testing using the DLN-CC tool. I then tried to inspect the image set using the DLN-Inspector tool, after updating the DLN database according to instructions in Appendix A1 of the User Guide DLN Inspector. When I opened the DLN Inspector, it shows me the Project Name in the first drop-down selection box, but it doesn't show any Image Groups in the second drop-down selection box. I've tried quitting and opening both the DLN-CC tool and the DLN-Inspector tools, but this doesn't make a difference. I've tried checking all my entries in the DLN-CC tool, but I can't find anything wrong. Do you have any suggestions for what else I should be checking? Other items: I found a couple of typos in the Appendix A.1.1 of the User Guide, DLN Inspector. In step 7, it states, This appears to refer to Step 3 rather than Step 2, and there isn't a scripts subfolder in the directory (Step 4 also refers to the scripts subfolder, which doesn't exist). Using DLN-CC, when I use the button "Save RDF" in the Image Sets Overview window, I get a series of java errors that says the following: However, I checked the directory for the image set and it does contain a new file named "dln-cptset.xml" that appears to contain all the relevant information for the image set. Best wishes, Taylor
  7. RTI's only “deliverable” is what end- users can see with the naked eye. RTI consistently presents more surface detail than conventional And I know it is very hard to predict the future of this but I am very thankful to you for if you guide me better
  8. Dag-Øyvind, I can't help directly, but a couple of suggestions, as it looks like it might be a graphics driver related issue: 1) It might help if you gave some details of your laptop make/model, operating system, and what graphics card it has. 2) Is the problem / that screenshot from the laptop's internal screen, or when using an external monitor? 3) If you haven't done so already, might be worth trying with an external monitor 4) It sometimes can be illuminating to temporarily try putting your laptop (internal screen and/or external monitor) into a different lower resolution 5) It would be worth checking for updates for your graphics card - from the operating system, and from both the laptop manufacturer and the graphics card manufacturer. 6) You say this is all projects, do you have a project which you can view OK on one PC but when you copy the files (or access over network) they give this faulty display? MVH Dave
  9. Hello! Since I got a new laptop, all my RTI projects is displayed with green lines across the surface when I open them in RTIViewer. I have tried to reinstall the software repeatedly, but with no success. Are you familiar with this problem and know how to solve it?
  10. Hi - yes - there are basic backup and restore capabilities in the Beta - and more sophisticated tools coming in the next release. Sorry it's been so long, but we are working hard on a new release now, with a lot of new functionality. So stay tuned. Carla
  11. MBennett, I don't know if there is any way you can synchronise or import chunks, but one possibility is if you have network connectivity, it might be possible to have various clients accessing one PostgreSQL database. Dave
  12. For those who have two separate dedicated capture setups, one in a Mac OS shop and one in a Win, can the db from one DLN setup from one OS be imported into another DLN instance on the other OS? I have two goals in mind: to enter project-independent parameterization data once, and to eventually consolidate and maintain a master DLN instance on one or the other OS that contains records of all of the photogrammetry projects conducted through both capture setups. Thanks.
  13. Ale, Particularly with PTM models, there are a range of visualisation aids, such as specularity, built in to the viewer already. Re "Metallic" - not sure what you're meaning exactly. RTI cannot perform any analysis of the subject's elemental composition by itself - you may get some clues from the photograph visual wavelength spectra, but you will get more - for bulk composition especially - using, say, XRF (X-Ray Fluorescence) - and hand-held XRF is becoming more common. Re "Roughness", there is work aplenty on machine vision assessment of 'roughness' as a production quality tool, using direct and scattered light and sometimes fractal analysis, but that is usually associated with prior reference data acquired with a similar part of known RA and RZ. I think it would be good if you could maybe explain your target / sample type / size / what you're trying to investigate. Dave
  14. Ale, I've posted an answer in the RTI dome acquisition section of the forum, suggest you might delete this duplicate question. Dave
  15. Ale, The idea of using addressable LEDs is definitely attractive; but I think it would harder than you think, and not very successful, to use those strips. 1) Those LEDs are not bright - you need a reasonably power light source to cast the shadows for the RTI process - or you need very long exposure times and noisy high ISO. 2) If you use such a strip, you will only be using a fraction of the LEDs 3) You can't just use, say, a sequential controller, you will need some form of programmable control - be it Arduino or PC or AVR or even TTL logic - to switch on the appropriate LED, let it settle, then fire the camera, and then repeat. Or, if your off-the-shelf controller allows you to specify switch on LED 74 at R=..G=..B=.. then you could do that manually, fire the camera, switch off LED 74 and then switch on, say, LED 81. 4) If you use such a strip, you will struggle to get the LEDs in the optimum position unless you cut the tape and solder fragments together (not actually difficult at all) and that is an attractive possibility (subject to note 1 above though) I have actually tried using strips similar to this as donors for a mini-dome, chopping into individual LEDS, placed appropriately around a dome and chaining them with soldered jumpers (light for data in/out, slightly heavier for power and ground, with extra power tapped-in periodically). However, results were not great due to low light output from individual LEDs. Dave
  16. Hello RT community, is it possible to get other optical data such as Metallic, Roughness with RTI dome? Thanks!
  17. Hello CHI community,First of all, thanks everyone for sharing such great knowledge here! : )I am planning to build a dome, but I am not familiar with welding and Arduino, so I taught of using a LED light strip such as the one bellow:https://neonica.eu/neonica-rgb-ic-sk-6812-led-strip-180-led.htmlThis strip has 5V led and can control led lights individually on a sequence (led1/led2, etc) with a small controller sold separately.My plan is to "glue" this strip inside a dome. Would that kind of setup work?Appreciate any inputs! : )Cheers

  19. Sometimes some of your apps don't work, your Mac gets slow, you get a spinning. ... Activity Monitor will ask if you are sure you want to quit this process. ... Instead, focus on the information displayed at the bottom right, at Data
  20. It looks like this a known problem with MACOS Catalina: https://forums.macrumors.com/threads/java-6-runtime-legacy-version-for-macos-catalina.2195954/ I am going to use this troubleshooting with students, but I wanted to the CHI folks to be aware that this might be an ongoing issue.
  21. Jackie, Regret I can't help directly (my last Apple PC was Apple-II on which I used UCSD Pascal for my PhD research!) but when you say you have removed the newest version of Java, I just wonder have you been able to remove all versions of Java. Certainly on Windows and some -ix operating systems, you can have multiple Java versions installed, so it is possible that although you removed one (the newest), there might be another slightly older, but still too new, version installed. One other thought if you can't resolve the MacOS installation is could you maybe run a virtual PC and clean-install windows thereon to give an environment to host required version of Java and then install RTI software in that virtual machine? Dave
  22. Hi! I am working with a student who has downloaded RTI builder on her computer and continues to get an error message: "To open "RTibuilder-v2.0.2" you need to install the legacy Java SE 6 runtime." She can click 'ok' or 'more info.' Clicking 'more info' leads us to the Java website but when she tries to download the selected Java she can't install as it says "Java for macOS 2017-001 can't be installed on this disk because a newer version of this package is already installed." We tried completely uninstalling and reinstalling the newest version of Java and completely uninstalling and reinstalling RTI builder. We got the same errors. RTI viewer downloads and runs fine. She has an early 2015 macbook running OS 10.15.17. Any help greatly appreciated! Thank you! Jackie
  23. Luke, This rings a bell for some years ago - I have a faint recollection someone found a case-sensitivity. 1) Suggest you rename your files ".jpg" and try again. If that fails, 2) Have you ever been able to make a PTM before? if so can you try that image set again? 3) If this is the first time you're trying to make a PTM, suggest you download the Fish Fossil image set from the CHI website and try them, as they are known to work OK with both HSH and PTM fitters. Dave
  24. Dear all, When attempting to create an RTI using PTM, an unknown error box pops up once I select execute. The PTMfitter output information states "Unknown File type: .JPG". I have had no issue creating a hsh rti with the same image set and it has only become an issue when attempting to create a ptm file instead. I am running this on a custom-made PC, Windows 10, 64-bit OS, 16GB RAM, AMD Ryzen 7 2700x 8-core at 3.70GHz. Any advice would be greatly appreciated - and any further information required, please ask. Many thanks, Luke
  25. Hi Fionn, A couple of thoughts / questions. 1) Generally, it is a good idea to give a little info as to operating system and version and 32/64 bits etc. 2) Can you grab a screenshot of the box on the RTI builder screen where you specify the location of the PTMFitter, like the attached please? 3) On this laptop (Windows 7-32 bit) my location is "C:\RTIbuilder_v2_0_2\Fitters\PTMfitter\PTMfitter.exe". One thing that I wonder is your error message just ends "... /PTMFitter" but on my Windows machine the ".exe" is recorded and shown in the path. Dave (from Fionn mac Cumhaill's rock in the Irish Sea!)
