The GigaMesh Software Framework is a free and open-source software for display, editing and visualization of 3D-data typically acquired with structured light or structure from motion.[3]

It provides numerous functions for analysis of

ceramics[4][5] or converted LiDAR data.[6] Typically applications are unwrappings (or rollouts),[7] profile cuts (or cross sections)[8] as well as visualizations of distances and curvature, which can be exported as raster graphics or vector graphics
.

The retrieval of text in 3D like damaged cuneiform tablets or

fingerprints can be visualized.[11][12] The polygonal meshes of the 3D-models can be inspected, cleaned and repaired to provide optimal filtering results. The repaired datasets are suitable for 3D printing and for digital publishing in a dataverse.[13]

The name "GigaMesh" refers to the processing of large 3D-datasets and relates intentionally to the mythical Sumerian king Gilgamesh and his heroic epic described on a set of clay tablets.[10]: 115  The central element of the logo is the cuneiform sign 𒆜 (kaskal) meaning street or road junction, which symbolizes the intersection of the humanities and computer science. The surrounding circle refers to the integral invariant computation using a spherical domain. The red color is derived from carmine, the color used by the Heidelberg University, where GigaMesh is developed.[citation needed]

Development and application in research projects

The development began in 2009 and was inspired by the edition project Keilschrifttexte aus

Machine Learning methods for other Scripts in 3D. An example is the application within the Text Database and Dictionary of Classic Mayan.[17]

In 2017 GigaMesh was tested by the

excavation in Guadalupe, near Trujillo, Honduras for immediate visualization of in-situ acquired findings with different 3D-scanners including a comparison with manual drawings.[18] Since then GigaMesh is permanently used by the excavation team,[19] their feedback led to numerous changes to the GUI, improving the user experience (UX)
. Additionally online tutorials are published having a focus on tasks required to compile excavation reports.

The Scanning for Syria (SfS)

TU Delft acquired further Micro-CT-scans for virtually extracting clay tablets still wrapped into clay envelopes, which are unopened for thousands of years.[23][24]
In May 2020 the SfS project won the European Union Prize for Cultural Heritage of the Europa Nostra in the category research.[25][26]

A first version (190416) for Windows was released in preparation for presentations about new functions shown at the international CAA 2019.[27]

The

Convolutional Neural Network typically used for 3D-datasets.[31][32] In 2023, an extension of the dataset was published containing extracted images of cuneiform characters, cuneiform lines and individual annotated cuneiform characters. The annotations are made available together with the renderings with metadata as CSV and a knowledge graph (RDF). These developments were created in the context of the DFG project "Digital Edition of Cuneiform Texts from Haft Tappeh" in Mainz. The acronym MaiCuBeDa is derived from the project location.[33] This provided the first results for the localization of cuneiform characters and their wedges, which show that MSII rendering improves the recognition quality for photos.[34][35]

The Louvre showed GigaMesh based rollouts of an Aryballos from the collection of the KFU Graz representing the use of digital methods for research on pottery of ancient Greece within the CVA project, which had its 100th anniversary in 2019. Renderings of the rollouts were on display in the second half of 2019 in the display case named L’ère du numèrique et de l’imagerie scientifique (the digital era and scientific imaging).[36]

Version 191219 supports

Cultural Heritage and in archaeology.[citation needed
]

The Nara National Research Institute for Cultural Properties in Japan adapted GigaMesh for documentation and rollouts of vessels and published a tutorial,[37] which was used to implement the workflow for ceramics of the Jōmon period within the Togariishi Museum of Jōmon Archaeology.[38]

In April 2020 the source code was published on GitLab and the license changed from freeware to the GPL. Version 200529 allows for the first time to apply the MSII filter using the Graphical User Interface to visualize the smallest details like fingerprints.[39] The DFG funded edition of texts from Haft Tepe project[40] is using MSII filtered renderings of tablets in the so-called fat-cross arrangement of side views.[41]

GigaMesh is increasingly being used in areas that have methodological overlap with archaeology, such as

seashells.[42]

File formats and research data infrastructures

Primarily the

Digital Object Identifiers (DOIs) can be captured. In addition, there is the ability to calculate topological metrics that describe the quality of a 3D measurement dataset.[43]
