Slide transition speed in impress.js

One of ATOR's purposes is to serve as some kind of reminder for all the tricks and actions we find out during our hacking sessions.

Today I'm preparing a presentation  with impress.js.

After my last lecture a listener told me that the transition speed between the single slides of my presentation was to fast.
I was moving across aerial photos, zooming in and out on points of interest.

After some groping in the dark I found the solution on github.

It's very easy:

Look for your impress.js file, open it with an editor and look for the tag "transitionDuration".
You will find it among the defauld config values, it's expressed in milliseconds. 6000 means 6 seconds of transition time.

Consider that this option defines an equal transition time for the whole presentation.
It's also possible to set different speed for every single slide transition.

OpenMVG VS PPT

Hi all,

as I promised, we are back with new post in ATOR. We start today with an experiment we wanted to do since long: a comparison between two Structure from Motion - Muti View Stereoreconstruction (SfM - MVS) suite. The first is Python Photogrammetry Toolbox, developed by +Pierre Moulon some years ago and integrated in ArcheOS 4 (Caesar) with the new GUI (PPT-GUI) written in Python by +Alessandro Bezzi and me. The second one is the evolution of PPT: openMVG, which Pierre is developing since some years and that will be integrated in the next releases of ArcheOS.

Our small test regarded just four pictures taken with a Nikon D5000 on an old excavation. We want to point out the speed of the overall process in OpenMVG, which gave a result compatible with the one of PPT.

In the image below you can have an overview (in +MeshLab) of the two pointclouds generated bye the different software: openMVG processed a ply file with 391197 points, while PPT gave us a result with 425296 points.

Comparison of the two models generated by opnMVG and PPT

The main different stays in the processing time. In fact, while PPT needed 16 minutes, 11 seconds and 25 tenths, openMVG complete the model in just 3 minutes, 28 seconds and 20 tenths.

Here below I report the log file of openMVG, where you can see each step of the process:

STEP 1: Process Intrisic analysis - openMVG_main_CreateList took: 00:00:00:00.464
STEP 2: Process compute matches - openMVG_main_computeMatches took: 00:00:01:13.73764
STEP 3: Process Incremental Reconstruction -  openMVG_main_IncrementalSfM took: 00:00:00:47.47717
STEP 4: Process Export to CMVS-PMVS - openMVG_main_openMVG2PMVS took: 00:00:00:00.352
STEP 4: Process Export to CMVS-PMVS - openMVG_main_openMVG2PMVS took: 00:00:00:00.352
STEP 5: Process CMVS-PMVS took: 00:00:01:25.85958
--------------------
The whole detection and 3D reconsruction process took: 00:00:03:28.208258

We will go on in working and testing openMVG, hopfully posting soon news about this nice software.

Have a nice day!

Intervallo n° 2

As you probably noticed it is a long time we do not write something new in ATOR and the reason is simple: summer is the most productive season for archaeologists, so most of us are working in the field and we have no time for new post.

Luckily we are engaged in new interesting projects and this will give us the opportunity to experiment new solutions and test new techniques, so we will have soon new material to share through ATOR.

In the meantime, like I did in 2013 with this post, I leave you with a short "Intervallo", just to tell that we are still active and that we will come back soon with new post and articles.

Have a nice day!

A small celebration for ATOR: 300000 visits

Hi all,

Once again thank you all for your feedbacks, your interest and your support in helping us with our experiment of open research in archeology.

300000  thanks!

July 27, 2014: just another birthday for ATOR

... and here we are: the third birthday of ATOR! 

To respect the "tradition" (1st anniversary, 2nd anniversary), today I'll publish some data about our "open research" blog.

This year, unfortunately, there are no new entry between the active authors (or AuThORs, as someone already says), but the number of post has (obviously) increased from 160 to 215, leading to 767 comments from the community. Currently (22:31 p.m. in Italy) we had 253116 visualizations (41708 since last reset of the revolvermaps counter... this time it was my fault). Our members are, up to now, 85 and this means that we have 24 new regular readers.

In my opinion, our little experiment in "sharing tests, problems and results" of our research is working, due to some events that have occurred over the past three years:

1. through ATOR, Arc-Team's research in archeology increased in terms of development and results
2. ATOR's post were useful also for other disciplines and sciences (soon more news about this topic)
3. oldest project (e.g. ArcheOS) took advantage form ATOR visibility
4. new projects (e.g. Taung project) and derivatives subprojects (e.g. the exhibition "Facce") started also thanks to ATOR
5. we have improved our English :)

As I wrote last year: "This short post is intended as a thanks for all the people composing the community of ATOR, readers and authors as well", but this time I want to mention the authors (in alphabetical order), without which our blog could not exist:

+Roberto Angeletti

+Alessandro Bezzi 

+Luca Bezzi 

+Brigit Danthine 

Bernhard Fischer 

+Denis Francisci

+Rupert Gietl 
+Domenico Giusti

+Szabolcs Köllö

+Cícero Moraes 
Mattia Segata
+Moreno Tiziani

+Leonardo Zampi

Thank you all!

Petition for Open Data in Italian Cultural Heritage

Yesterday I had the opportunity to attend a very interesting event: the School of Data held in Trento (to tell the truth, for working reason, I could see just the last part of the meeting, but it was very instructive). 

There, among others, I met Maurizio Napolitano, one of the greatest expert of Open Data here in Italy, and he mentioned an important initiative which I did not know, that is a petition for Open Data in Italian Cultural Heritage.

This "minipost" is intended to help the petition to reach the objective (some legislative amendments to allow and encourage the use of Open Data in our work, which is also, of course, one of the aims of ATOR).

Here is the link to sign the petition. The goal is set for 200 signatures before December 31, but I think we can do something more :).

Here below you see the main page of the website beniculturaliaperti.it, where the petition is host.

Thanks for your time and for any help you will give to this cause.

Happy birthday ATOR! Two years of Open Research

The 27th of July is the "birthday" of ATOR and like last year in this day I would like to share some statistics about the progress of this experiment.

In one year, the number of active authors has increased from 6 to 13, while the posts reached the quote of 160 (79 last year). The reactions of the community led to 271 comments (96 of which were written in 2012). Currently (19:16 pm) the number of visualizations is 109447 (48899 visits since the activation of the Revolver Maps plugin) and we have 37 new members which, added to the 25 persons of 2012, bring the total number to 61 people.

As you see in the image below the main celebration for 2013 is the achievement of 100000 visits.

This short post is intended as a thanks for all the people composing the community of ATOR, readers and authors as well. 

Thank you for your posts, feedbacks and support! 

Your help was very important in improving and speeding up the research presented in this blog. Thanks to you we reached results which, initially, were not foreseen and in some cases ATOR gave birth to new methodologies that have become rapidly very popular in the scientific community . 

We hope to keep this trend also in the next year and to maintain an high quality level in the field of Open Research!

Intervallo

Never did eye see the sun unless it had first become sunlike, and never can the soul have vision of the First Beauty unless itself be beautiful
(Plotinus, Enneads)

Hi all,

as you noticed in the last month we did not write many posts in ATOR. The reason is simple: actually all the most active authors are very busy with their respective work. The good news is that in the meantime we are collecting a lot of data and ideas that hopefully will soon become new articles for the blog.

However I decided to write this fast post just to reassure you that we will come back ASAP and, as always, we will share data, texts, experiments, software and everything else it will be necessary to achieve our goal: an Open Research in archeology (and beyond). 

Today I have too few time to share something useful, but I can aways share something beautiful: some pictures we took working around. I hope you may like them. 

PS

The title and the music of the slideshow are an inside joke for ATOR Italian community (most people will remember the old "intervallo RAI" which was used during technical problems) :)

July 27, 2011 - July 27, 2012: a year of ATOR

Hello all,

today ATOR reaches its first year, so I thought to post and analyze some statistics to see how this experiment of shared research is progressing.

Until now we have six active authors, who wrote 79 posts. The community reacted with 96 comments, although most of them are written by the authors in response to direct questions from readers. Overall the blog counted 21484 visits (8695 visits since the activation of the Revolver Maps plugin, as you can see in the image below).

Today ATOR has 25 members and the general trend is still growing, but sinlge posts may affect the statistics with an increase of visitors related both to the quality of the post and to the interest aroused by the topic. A good example of this situation is the post of Cicero Moraes about forensic facial reconstruction, which has captured the attention of the community of 3D modelers and of physical anthropologists, reching the peak traffic you can see in June 2012 in the graph below.

The post reached also the attention of Ton Roosendaal (original creator of Blender), who wrote a tweet about it:

Anyway, the main strength of ATOR and of an open approach to research remains the active collaboration between researchers operating in different fields (not only archaeologists). In this case must be placed, for example, the new collaborations with the 3D artist Cicero Moraes (already mentioned) and with the anthropologist Moreno Tiziani, creator of anthropological association Antrocom Onlus, which publishes the Online Journal of Anthropology. 
We will go on working with this open philosopy in archaeology, inspired by the Free/Libre and Open Source Software movement, and to further increase the quality of posts in ATOR with the help of the community. As usual, if you want to collaborate, just contact us! 
Thank you.
