Description:
#P2C-Converter
##Description
Converts Polar Coordinates into Cartesian Coordinates.

##AstroSynthesis Description
This is not an AstroSynthesis plugin but a standalone conversion app written on Python (you need any version of Python as this is super simple app and works on any version starting with 2.7). Read ##Instructions section clearly to run the app!

##Mechanics
-Feeds on data from import.csv;
-Calculates translation of coordinate systems;
-Produces export.csv file;

##Instructions
Use import.csv that comes with the app to create your own import file, save with radius, polar, alpha columns. Do not use the raw_polar column, as it is there only for specific calculation with image being only visible from a specific view. The excel table provides simple solution to this by switching X and Y coordinates and accounting -12.859 degrees of sheer of the original image.

&gt;Start - Windows Terminal
&gt;
&gt;pip install pandas
&gt;
&gt;cd \path-to-P2C-Converter
&gt;
&gt;P2C-Converter.py

##Story
I created it out of pure interest to see how python is working and I needed an app that converts Polar coordinates of stars based on an image of the galaxy that I created earlier ;)

I have an image of the galaxy drawn on a piece of paper and it was drawn as a whole not as a map. I wasn't able to figure out what X,Y,Z coordinates on that image the stars had so I used Polar Coordinates system to figure out that.
The app takes the FURTHER XYZ 0-Point of an imaginary cube surrounding the image in question.
