3D-Photo – survey with XTion and Skanect
3D-Photo – survey with XTion and Skanect
A previous article reported a first experiment with XTion and Scanect. At that time, 2 years ago, results were average in terms of quality, usage and stability. (see here)
The new 2015 version (1.8) of the software (http://skanect.occipital.com/) brings much more confort and good results. Continuer la lecture de 3D-Photo – survey with XTion and Skanect

On this graphic below, is shown where from the total eclipse can be seen. Sur le graphique ci-dessous, est montré d’où l’éclipse totale peut être vue.
The best position to oberve the total eclipse would be in the Feroe Islands. La meilleure position pour voir l’éclipse totale serait aux iles Féroé.
Let’s see it with animation / Voyons cela en animation.

Moon and sun are like in the same arc. That explains why, the eclipse will occur this day. La lune et le soleil sont pratiquement sur un arc identique, ce qui explique pourquoi l’éclipse a lieu ce jour.
