Use fourier transform to draw epicycles with your drawings.

Draw a picture or sample one, press space, then watch an epic simulation of epicycles being drawned identically as your picture. Thanks the the fourier transform your drawing will be reproduced in a real-time simulation only using epicycles.

Demo

Install

#Clone the repository
git clone https://github.com/MarcPartensky/Fourier.git
cd Fourier

#Install requirements
pip install -r requirements.txt

Usage

Put your model image image.png in the FourierImages folder.

• Option 1: Give image at launch.

python __main__.py image.png

• Option 2: Launch then give the image.

python __main__.py
> image name:

Then give your image:

> image name:image.png

Run with docker

# Download the docker-compose.yml file and cd into its parent folder
# Put your image in the FourierImages folder then run
# Replace 'image.png' by your own image filename
docker-compose run --rm fourier image.png

Or choose your own folder

# Download the docker-compose.yml file and cd into its parent folder
# Replace the first occurence of 'FourierImages' by your custom image folder
# Replace 'image.png' by your own image too
docker-compose run --rm \
    -v ./FourierImages:/opt/FourierImages \
    fourier image.png

Or run the full docker command without the docker-compose.yml file

docker run --rm \
-v $PWD/image.jpg:./image.jpg \
-v /tmp/.X11-unix:/tmp/.X11-unix \
--device /dev/dri \
-e DISPLAY \
marcpartensky/fourier /image.jpg

Or store the coefficients and the images in a folder

docker run --rm \
-v $PWD/FourierImages:/opt/FourierImages \
-v $PWD/FourierObjects:/opt/FourierObjects \
-v /tmp/.X11-unix:/tmp/.X11-unix \
--device /dev/dri \
-e DISPLAY \
marcpartensky/fourier image.jpg

Description

There are 3 modes in this program:

• Mode 1: Sampling Sample or draw a picture.

• Mode 2: Drawing Watch the epicycles simulation which uses fourier transform.

• Mode 3: Display Get the output image directly without waiting for the simulation.

Controls

• Space: Switch to next mode.
• Enter: Go back to the center.
• Up/Down/Right/Left Arrow: Move arround.
• Right/Left Shift: Zoom in or out.
• Quit/Escape: Quit.
• Z: Cancel last sample.
• R: Remove all samples.
• S: Save the fourier-coefficients.

Press the following numbers to toggle:

• 1: Image
• 2: Green lines
• 3: Red graph
• 4: White vectors
• 5: Grey circles
• 6: Yellow sample
