Geo-Astronomical library for artist

Hypatia is a geo-astronomical library based on the work of Jean Meeus, Mark Huss, Bill Gray, Stuart Lowe, Brandon Rhodes , Daniel Warner, Oliver Montenbruck and Thomas Peleger. Was created mostly for educational purposes, but also to use in different personal artistic projects.

In comparison with other astronomical/geographical libraries created for profesional uses Hypatia have a focus on:

• reusability and portability
• realtime performance
• simplicity of the interface, than other

Hypatia as C++ lib

You can easily add hypatia into your project by adding the include/ and src/ folder or by installing hypatia into your system. For the former option you need to:

sudo apt install cmake swig
mkdir build
cd build
cmake ..
make
sudo make install

#include <sstream>

#include "hypatia/Body.h"
#include "hypatia/Luna.h"
#include "hypatia/Constellation.h"

void main(int argc, char **argv) {

    obs = Observer(40.781098831465, -73.97715657655);

    sun = Body(SUN);
    moon = Luna(LUNA);
    std::cout << "Moon's phase: " << moon.getPhase() << std::endl

    const = Constellation(moon)
    std::cout << "Moon's transit constelation: " << const.getName() << std::endl

    return 0;
}

Hypatia as Python module

First you need to create the package and install it

sudo apt install swig
make install

Note: to install inside anaconda do:

/anaconda3/bin/./python3.7 setup.py install 

Then you can use it as follow:

from hypatia import *

obs = Observer(40.781098831465, -73.97715657655)

sun = Body(SUN)
sun.compute(obs)

moon = Luna(LUNA)
moon.compute(obs)
print("Moon's phase: ", const.getPhase())

const = Constellation(moon)
print("Moon's transit constelation: ", const.getName())
