mapping-converter's Introduction

mapping-converter

This code is still not finished, but a working one was written in openframeworks available here: https://github.com/magdesign/mapping-converter2

With this tool you are able to convert .svg output from video mapping software like Madmapper, Mapio or Resolume to PiMapper surfaces.
Its not finished yet, but the basic concept works.

##Problems to solve:

Dont know how to get the zero points, the quads size is correct, but position not, tryed to add numbers like x value + 960 and y value +540....
Define if it is a quad or trianle, surface type="0" is triangle, surface type="1" is quad
Any help very welcome..

Here you see the two masks I exported from Madmapper:

and here you see how this looks then in PiMapper after converting with this tool:

the size looks the same, but the placing... and I guess it eats the content mirrored..

##Instruction

Copy parser_one_file.py to a folder.
Place a slices.svg (I used an .svg exported from Madmapper) in the same folder as the script.
cd into your folder and run: python parser_one_file.py
output the .xml file for PiMapper, do something like: python parser_one_file.py > /path/to/file/surfaces.xml
Then copy this file to your PiMapper, located somewhere here (depending where you isntalled openframeworks: /home/pi/openFrameworks/addons/ofxPiMapper/example/bin/data/surfaces.xml

Difference between the parser.py and parser_one_file.py, the later is only made for .svg with one quad inside, parser.py is made for more than one quad, and looks for a file called slices2.svg

You might need to install depencies first: pip install svgtools svgpathtools svgwrite
