Goemaat's MANIM Experiments

Learning python and wanted to try out some visualizations like those 3blue1brown creates for his videos

Setup

Installed Conda

I did the regular Windows installation of Anaconda. This is like an environment manager for python. It lets you setup environments with their own sets of python and library versions, preventing errors you might have if using pip to isntall different version of packages globally to use python.

Conda Environment

Conda installed a link in my start menu for 'Anaconda Powershell Prompt' which I use. To install manim, I setup an environment named manim and installed it:

conda create -n manim
conda activate manim
conda install -c conda-forge manim

First Render

Starting the 'Anaconda Powershell Prompt' and selecting our 'manim' environment in conda:

conda activate manim

Creating a file 'circle.py' with one scene that renders a circle:

from manim import *

class CreateCircle(Scene):
    def construct(self):
        circle = Circle()  # create a circle
        circle.set_fill(PINK, opacity=0.5)  # set the color and transparency
        self.play(Create(circle))  # show the circle on screen

Running manim to generate a video and play it

manim -p circle.py -a

Using opengl:

add manim.opengl import to enable
pass --renderer=opengl to render to a window using opengl
add self.interactive_embed()

from manim import *
from manim.opengl import *

class CreateCircle(Scene):
    def construct(self):
        circle = Circle()  # create a circle
        circle.set_fill(PINK, opacity=0.5)  # set the color and transparency
        self.play(Create(circle))  # show the circle on screen
        self.interactive_embed()

manim -p circle.py -a --renderer=opengl

Interactive Render

This lets you render to a window that is left open and interact using a console and mouse/keyboard.

Install IPython:

conda install -c conda-forge IPython

Using the opengl as base, add self.interactive_embed()

from manim import *
from manim.opengl import *

class CreateCircle(Scene):
    def construct(self):
        circle = Circle()  # create a circle
        circle.set_fill(PINK, opacity=0.5)  # set the color and transparency
        self.play(Create(circle))  # show the circle on screen
        self.interactive_embed()

To render to a movie file still you can pass --write_to_movie which will disable interactivity and render a video

manim -p --renderer=opengl --write_to_movie circle.py -a
