ArcheOS Hypatia 3DHOP package (call for testing)

This short post is related with the previous one (about Nexus) and it is a call for testing for the deb binary package (arm64) of 3DHOP, the software developed by the Visual Computing Lab (CNR-ISTI, Pisa - Italy) to create interactive and multi-resolution web-galleries of 3D objects.

Here below you can see just an example of a gallery related with conflict archeology (WW 1), which we are developing in these days.

Example of a 3D web-gallery with 3DHOP (work in progress)

Being a Debian Jessie derivative distro, ArcheOS Hypatia will install 3DHOP in the folder /var/www/html/3dhop-3.0.
The best way to practice with this software is to modify the code of the different examples the package comes with (they are placed in /var/www/html/3dhop-3.0/examples).
For people that wants to help ArcheOS development and test this package, I upload it here. Soon we will prepare also 32-bit packages.

I hope this package will be useful! Merry Christmas and Happy new year!

PS

Marco Callieri (Visual Computing Lab - CNR-ISTI) notified me that Nexus and 3DHOP are under development right in these days, so there will be probably a new version in a short time. As soon as there will be changes, I will update the packages with the new functionalities.

ArcheOS Hypatia Nexus package (call for testing)

Hi all,

Since we are working on a project related with a 3D gallery of WW1 remains, we are using the 3DHOP application (which has been also suggested by Nicola Schiavotiello in the ArcheOS-dev Mailing List), developed by the Visual Computing Lab of the CNR-ISTI (Pisa - Italy). In order to exploit the full potential of this software it is useful to use the tool Nexus (see the related issue in ArcheOS github) , to create batched multiresolution mesh structures (to enable Level of Details  - LoD - visualization). 

An example of simple visualization in 3DHOP

For this reason, today I took the occasion to build a simple binary package (for amd64), to be tested for ArcheOS. If someone wants to help in testing the package, it can be downloaded here. Please report in the comment of this post your feedbacks. 

Thank you all!

In order to implement the two new packages in ArcheOS Hypatia in a short time, we changed the architecture field of the control file of 3DHOP deb package to let it work with all the machines, while we compiled a new i386 package for Nexus. If you want to test the new packages, here are the new files:

3DHOP (architecture all)

Nexus (architecture i386)
Nexus (architecture amd64)

Soon we will update archeos-meta in order to implement these two software.

Any help in packaging is much appreciated!

WebRTIViewer

Hi all,

I write this post to complete the one +Rupert Gietl did regarding Large Scale Reflectance Transformation Imaging. As you read in that article, Rupert, using +GRASS GIS, re-built virtually the necessary light conditions to process an RTI image of an entire archaeological area. 

This is just one of the test we are carrying on with RTI techniques, since we are trying to evaluate this methodology under different aspects. Obviously, during our experiments, we encounter interesting researches carried on by other institutions. 

This post regards one of the projects we found on our way (I will write soon about other related works) and, more precisely, a software to share RTI images through internet: WebRTIViewer. Actually the source code of the application, an HTML5-WebGL viewer, is release under the therms of the General Public License 3 (GPL 3) on the website of its author: +Gianpaolo Palma.

Here is an example of its application, using Rupert's data of the archaeological site (better visualized here). To see it, just turno on the light and, holding the left button, move your mouse around.

The software comes with two binary tools (one for Windows 32 bit and the other for Windows 64 bit), which are necessary to prepare the RTI images for the viewer. For this reason I wrote to Giampolo Palma to ask if there would be the possibility to insert WebRTIViewer and the other applications in ArcheOS (to do this we would need the access to the source code of the binary tools, called webGLRTIMaker) and he kindly answered that he likes the idea and he would agree, but before to release the code of the webGLRTIMaker under an open license he will ask the opinion of his labs colleagues (the Visual Computing Lab). This institute, part of the Italian CNR-ISTI, is the same that develops other nice Free/Libre and Open Source (FLOSS) software, usefull in archaeology, such as MeshLab, which is often in our post, or 3DHOP (soon a post about it). Hopefully, if everything goes well, we will have another nice tool to add to the ArcheOS software selection, helping Cultural Heritage professionals in sharing data through RTI technologies.

Here below you can see again webRTIViewer in action (better visualized here), this time with data coming from the archaeological excavation of Khovle Gora (in Georgia), where we work for the University of Innsbruck (Austria) and support technically the fieldwork directed by Dr. Walter Kuntner of the Institut für Alte Geschichte und Altorientalistik.
