PDE Animation

PDEAnimation.mp4

Getting Started

git clone https://github.com/graysoncroom/PDEAnimation.git
cd PDEAnimation
python -m venv env
source ./env/bin/activate
pip install manim scipy

Now you'll be in a python virtual environment with the manim and scipy libraries installed.

Note that you'll need to source ./env/bin/activate every time you close your terminal and want to start working on the code again.

Rendering the animation(s)

Example:

manim -pqh src/matchsticks.py PDEAnimation

The -p option tells manim to open the animation in a video player after the rendering completes (stands for play).

The -qh option tells manim to render with high quality.

You could also give it -ql instead as your iterating on an animation and want the rendering to go faster.

src/matchsticks.py is the source file of your animation code

PDEAnimation is the class name of the manim class that describes the animation

Note: Whether you pass manim the -p option or not, the rendered video will be stored in the ./media directory. If a ./media directory doesn't exist, it will be created for you.

Problems and Solutions

If manim is complaining about libraries, check out the Manim Documentation

It's likely you'll need to install a few system-level libs (e.g. ffmpeg, libpango1, libcairo2, ...)

Note: Manim renders math text using Tex. Make sure you have a full Tex distribution (e.g. livetex w/ extras) before trying to render these animations.
