3DHOP for speleoarchaeology

Hello everybody,

today I go on writing about our speleoarchaeological project on the natural cave "Bus dela Spia". I prepared some material to share in later post, about the work-flow I followed in Blender, MeshLab, CloudComaper and GRASS GIS, but in the meantime I want to show the final result of my work in recovering old documentation (maps and sections), thanks to the FLOSS 3DHOP.

If you are a regular reader of ATOR, you know what I am speaking about. The software is developed by the Italian CNR (ISTI) and, more precisely, by the Visual Computin Lab (the same programmers who write the code of MeshLab). I chose this software due to its nice "slicer" tool, which allow the user to virtually cut a 3D model along one of the axis, to see other models hidden below (of course this is very useful in archaeology). This in not the only interesting tool (especially considering the updates of the last release), but, by now, is the one I want to show, also because I use it very often in another archaeological field: the Forensic Facial Reconstruction (in order to cut the face and show the cranium). Here below is a short video about this tool. Within 3DHOP are loaded 2 object: the Digital Terrain Model of the landscape and the 3D reconstruction of the "Bus dela Spia", performed in Blender. I hope you will enjoy it. Have a nice day!

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).

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!

LAST UPDATED 2016-01-29

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!
