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.

jsc3D: javascript for 3D models and scenes in the web

Hi all,

as I promised in this post today I write a short text about a very interesting software named jsc3D. 

This tool provides a 3D viewer to embed objects and scenes on a webpage. The code is Javascript and it is released with the MIT License (more info here). One of the best feature of this software is its intuitiveness, which makes it easy to use also for newbies. Moreover it works with obj file format, a very common and  open "standard" (de facto) for 3D models.

The versatility of the code is another very important peculiarity of this application.
As you see, I can import a simple scene here in blogger (e.g. layer 162 of the excavation of S. Andrea's church, Storo - TN - Italy)...

... while Giuseppe Naponiello (our webgis expert), used jsc3D to integrate a simple 3D viewer in Raptor (the open source webgis Arc-Team is developing for the Ministero per i Beni e le Attività Culturali)...

... and, again, I integrated this tool also in some presentation I did using the software impress.js, which will be the topic of one of the next post.

I hope this short informations about jsc3d will be useful for your projects. Have a nice day!
