Trigger when: (1) User mentions "manim" or "Manim Community" or "ManimCE", (2) Code contains `from manim import *`, (3) User runs `manim` CLI commands, (4) Working with Scene, MathTex, Create(), or ManimCE-specific classes.
|
||||
|
||||
Best practices for Manim Community Edition - the community-maintained Python animation engine. Covers Scene structure, animations, LaTeX/MathTex, 3D with ThreeDScene, camera control, styling, and CLI usage.
|
||||
|
||||
NOT for ManimGL/3b1b version (which uses `manimlib` imports and `manimgl` CLI).

||||
|
||||
- [templates/basic_scene.py](templates/basic_scene.py) - Standard 2D scene template
|
||||
- [templates/camera_scene.py](templates/camera_scene.py) - MovingCameraScene with zoom/pan
|
||||

|
||||
|
||||
## Quick Reference
|
||||
|
||||
### Basic Scene Structure
|
||||
```python
|
||||
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
|
||||
```bash
|
||||
# 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:
|
||||
|
||||
```python
|
||||
%%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 **Outdated tutorials** - Video tutorials may be outdated; prefer official documentation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
|
||||
|
||||
```bash
|
||||
# Install Manim Community
|
||||
pip install manim
|
||||
|
||||
# Check installation
|
||||
manim checkhealth
|
||||
```
|
||||
|
||||
### Useful Commands
|
||||
|
||||
```bash
|
||||
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
|
||||
```
