Generative paintings by Delaunay triangulation.

Presented at SIFISC 3 (2013) at IFSC/USP as:

    Pinturas generativas por tesselação de Delaunay. Estudo #4

    ----------------------------------------------------------

    Imagens de pinturas originais dos movimentos Barroco e Moderno foram

    segmentadas. Coordenadas de pontos pertencentes a esses segmentos foram dadas

    como entrada para o algoritmo de tesselação de Delaunay. O algoritmo cria uma

    malha a partir da triangulação das coordenadas dadas, sem cruzamentos de

    arestas. A cor de cada triângulo da malha equivale à cor média do segmento da

    pintura original.

All generated paintings ([the whole set](http://www.flickr.com/photos/auto_mata/sets/72157634660390040/)):

# Installation

At a Linux workstation:

    sudo apt-get install python python-numpy python-matplotlib python-setuptools git

    git clone https://github.com/scikit-image/scikit-image.git

    cd scikit-image

    sudo python setup.py install

    cd ..

    

    git clone https://github.com/automata/tri-delaunay.git

    cd tri-delaunay

# Usage

To generate a painting from any PNG file:

    python tri.py foo.png

    

It will generate ''foo_pintura.svg''.

    

To generate a file showing all the steps:

    python tri_passos.py foo.png

    

It will generate ''foo_passos.svg''.
