New release today improving #glTF export i.e. smaller files (no normal option) and vertex color support. Download: gigamesh.eu/downloads #FDM @nfdi4objects @nfdi4culture @NFDI_de
There is another non-heritage use case for GigaMesh to determine potholes in roads using low-cost #LiDAR sensors in the Journal of Location based Services by colleagues at @UniFAU & @TU_Muenchen: doi.org/10.1080/17489725.202…
For our German speaking colleagues - there is a Friday lunch time #webcast about #Datamanagement in #Archaeology. Wondering if #3D will be part of it as Martina is known to have worked with e.g. odeeg.acdh.oeaw.ac.at/ #FDM
Wir freuen uns, für den nächsten Webcast
"𝐃𝐚𝐭𝐞𝐧𝐦𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐭 𝐟𝐮̈𝐫 𝐀𝐫𝐜𝐡𝐚̈𝐨𝐥𝐨𝐠𝐞𝐧"

MSII filtering can be applied to #RTI/
#PTM datasets when converted to 3D. Great cooperation with LDA Sachsen-Anhalt and @Fraunhofer_IFF creating a curvature based 2D/3D benchmark dataset. 👇👇👇
🆕📢 New paper alert!

#NewRelease with #glTF export by @EStoetzner for Linux, which is not complete in terms of color support for #3D #meshes. @nfdi4culture @nfdi4objects There are also other smaller fixes and improvements (see gigamesh.eu/news/).
Currently experimenting with a glTF export function. Interestingly this format is not very efficient as files are three(!) times larger than ASCII PLYs or OBJs. Not very well suited for long term storage and archival #FDM #researchdatamanagement #3D @nfdi4objects @nfdi4culture
Reason seems to be a compute time optimization for fast rendering. This will also cause issues for import capabilities and tasks like (re)editing #3D #annotations.
Thanks to a colleague at @leizarchaeology & @i3mainz we found out about another user and his Open Access dataset from Kalba, United Arab Emirates, of the @ShjArchaeology (SAA), the @oeai_oeaw @oeaw:

Eine neue KI kann schwer zu lesende Texte auf Keilschrifttafeln entschlüsseln. Entwickelt wurde sie von einem Team der MLU, der Hochschule Mainz & der @uni_mainz. Die KI nutzt statt Fotos 3D-Modelle der Tafeln & liefert deutlich zuverlässigere Ergebnisse. mlu.de/f21my

German chapter meeting of @CAA_Int - quite some 3D topics 😊👍👇👇🏻👇🏾
New types of #3D objects sometimes require new methods as presented in the @CAA2023 pre-print. These are existing outside of GigaMesh for now. However, looking carefully at GM's changelog one will notice the automatic orientation option, which works best on #lithic tools 😉😊
#Paperalert pre-print for the @CAA2023: is online doi.org/10.5281/zenodo.82962… featuring the new methods, tools & dataset for #3D feature segmentation (ridge/scar) and representation for lithic artifacts by @Fractal_Linsel and @JPBullenkamp. Newest insights next week @CAADE5 😉
#Paperalert for MSII #3D renderings and #artificialintelegence assisting Digital Ancient Near Eastern (#DANES) Studies in cuneiform sign recognition 👇👇👇
@situxxx presented the joint work @i3mainz-@UniHalle today at #GCH2023. The article is now available #OpenAccess: doi.org/10.2312/gch.20231157 #OpenDANES #DANES (Digital Ancient Near Eastern Studies) #3D #artificalintelligence #eHumanities
Scholars in Japan are also among our earliest international users. Very happy to see that they bring results to the 2023 @archaeologyEAA conference 😊 👇👇🏻👇🏾
Putting together my slides for next weeks @archaeologyEAA conference (#EAA2023), hopefully making an impact with some high-res pottery photos made using @MeshGiga!
Come join us in session 600! 😇
#OpenAccess Dissertation about 3D acquisition with UAVs. @ChristianSeit15 is also an early adopter of GigaMesh. So there are nice applications also on larger objects in his thesis 👇👇🏻👇🏾
I am pleased to announce that my PhD thesis entitled "ArchEyeAutomatic: UAV-Based Documentation of Monuments in Archaeology" is now available (open access): doi.org/10.17192/z2023.0514
#spoiler: #3D renderings with virtual light and #MSII filtered cuneiform tablets improve results for sign detection on renderings and photographs. Another small step towards a #Cuneiform #OCR. Also #HeiCuBeDa got #Cuneur annotations and becomes #OpenAccess #MaiCuBeDa.taset.
Coming soon/in print: "R-CNN based Polygonal Wedge Detection Learned from Annotated 3D Renderings and Mapped Photographs of Open Data Cuneiform Tablets" by @EStoetzner & #MaiCuBeDa by @situxxx as well as @JPBullenkamp at @eurographicsorg #GCH23 workshop.
