Quick Reference

Basic Scene Structure

from manim import *

class MyScene(Scene):
    def construct(self):
        # Create mobjects
        circle = Circle()

        # Add to scene (static)
        self.add(circle)

        # Or animate
        self.play(Create(circle))

        # Wait
        self.wait(1)

Render Command

# Basic render with preview
manim -pql scene.py MyScene

# Quality flags: -ql (low), -qm (medium), -qh (high), -qk (4k)
manim -pqh scene.py MyScene

Key Differences from 3b1b/ManimGL

| Feature | Manim Community | 3b1b/ManimGL | |---------|-----------------|--------------| | Import | from manim import * | from manimlib import * | | CLI | manim | manimgl | | Math text | MathTex(r"\pi") | Tex(R"\pi") | | Scene | Scene | InteractiveScene | | Package | manim (PyPI) | manimgl (PyPI) |

Jupyter Notebook Support

Use the %%manim cell magic:

%%manim -qm MyScene
class MyScene(Scene):
    def construct(self):
        self.play(Create(Circle()))

Common Pitfalls to Avoid

1. Version confusion - Ensure you're using manim (Community), not manimgl (3b1b version)
2. Check imports - from manim import * is ManimCE; from manimlib import * is ManimGL
3. Outdated tutorials - Video tutorials may be outdated; prefer official documentation
4. manimpango issues - If text rendering fails, check manimpango installation requirements
5. PATH issues (Windows) - If manim command not found, use python -m manim or check PATH

Installation

# Install Manim Community
pip install manim

# Check installation
manim checkhealth

Useful Commands

manim -pql scene.py Scene    # Preview low quality (development)
manim -pqh scene.py Scene    # Preview high quality
manim --format gif scene.py  # Output as GIF
manim checkhealth            # Verify installation
manim plugins -l             # List plugins
