SunTrajectory.net

http://SunTrajectory.net enables you to predict the sun path and its shadow, simply looking through your phone.
Find sunrise and sunset times, not only on the horizon, but also depending on a building or a mountain.
The summer and winter solstices show the extreme positions of the sun over a year.
You can also predict the shadow, the sunlight in and out of a house, and even where the sun will be... if reflected in water!

Caution: some phones don't handle correctly gyroscopic sensors. Should you notice any innaccurate display, try deactivating gyros into application menu/settings.

http://SunTrajectory.net allows you to display the future trajectories of the sun in augmented reality:

* Look through your phone and see the path of the sun.

* Plan the sunrise and sunset times, not only on the horizon, but also on a building or a relief.

* Travel in time and see what course the sun will follow in the months to come.

* The summer and winter solstices are displayed, showing the extreme positions of the sun over a year.

* Take and save photos.

* Check afterwards the different trajectories of the sun for a whole year.


Moon Path is included:

* http://MoonTrajectory.net is fully included into http://SunTrajectory.net!

* No need to have both apps installed on your phone.

* You can browse the trajectories of the sun, its shadow and also of the moon on the same photos!

* Find out if the moon will be full or what phase it will be in.

* For more details, please visit the website of
http://MoonTrajectory.net.


Architecture:

* Visualize the sunlight in and out of a house you wish to buy for every month of the year.

* Predict the consequences of a shadow.

* Think about the orientation of a terrace, imagine creating a new window.

* Export your photos, including the drawing of the sun path, to your computer and integrate those pictures into a report (for example: photovoltaics).


Photography:

* Plan your pictures according to the light effect you wish to create.

* Plan when a subject (like a statue for instance) will be lit from the angle you have chosen.

* Plan when that same subject will be aligned with the moon.

* Use the calendar of the moon phases.

* Plan when the sun will light a scene (and not be hidden by a mountain or a building).

* Imagine the outline of shadows on the scene at a later date.

* Use the agenda to plan your future pictures.

* This way, you will know when to return to the site to take your picture to the maximum effect.

* Use Google Maps to pinpoint its exact location.
