About Planet Fun
PlanetFun is a 4D solar system simulation (3D + time)
Sun, planets, Moon and star positions are calculated using
various astronomical methods.
App source code (Delphi Firemonkey) is available at:
https://github.com/omarreis/vsop2013
PlanetFun features:
* Solar system animation with configurable speed
* Set any local date and time
* Choose camera target (Sun, planets, etc)
* Configurable camera distance-to-target
* Touch gestures: one finger pan, two finger zoom, two finger rotation
* show planet orbits. Each orbit is represented by 52 dots (for Earth it is one dot per week)
* Heliocentric axis (x and z)
* VSOP2013 and VSOP87 planet position calculations
* Moon positions calculations ELP2000
* Star background image with 42455 stars of the Hipparcos Input Catalogue
* Star and constellation lines and names ( a celestial sphere image )
* Constellation drawings ( 31 constellations )
* actual 3D spheres for the 150 brightest stars
* Lighthouse on Earth on your GPS position
* phone in the scene is positioned according to phone sensors (Azimuth,Elevation,Roll)
* click the phone button to enter augmented reality mode.
* Almanac module allows exploring the ephemeris calculators (stars, planets, Sun, Moon, Earth)
controls:
* camera distance and angle of view.
* planet scales
* local time, time animation speed
* control visibility of various interface elements
* app uses sensors compass, gyro and GPS - requires permission
This app collects no user data.

* Fixed Polaris position
* Config dialog was split in 3 smaller dialogs ( time, camera and visibility )
this improves interactive configuration.
* Changed axis from ecliptic to celestial reference.
* Textures moved to external files to simplify source code publication on github.
