- [rules/embedding.md](rules/embedding.md) - self.embed() for IPython debugging, touch() mode

### Configuration & CLI

- [rules/config.md](rules/config.md) - custom_config.yml, directories, camera settings, quality presets

## Working Examples

Complete, tested example files demonstrating common patterns:

- [examples/basic_animations.py](examples/basic_animations.py) - Basic shapes, text, and animations
- [examples/math_visualization.py](examples/math_visualization.py) - LaTeX equations and mathematical content
- [examples/graph_plotting.py](examples/graph_plotting.py) - Axes, functions, and graphing
- [examples/3d_visualization.py](examples/3d_visualization.py) - 3D scenes with camera control and surfaces
- [examples/updater_patterns.py](examples/updater_patterns.py) - Dynamic animations with updaters

## Scene Templates

Copy and modify these templates to start new projects:

- [templates/basic_scene.py](templates/basic_scene.py) - Standard 2D scene template
- [templates/interactive_scene.py](templates/interactive_scene.py) - InteractiveScene with self.embed()
- [templates/3d_scene.py](templates/3d_scene.py) - 3D scene with frame.reorient()
- [templates/math_scene.py](templates/math_scene.py) - Mathematical derivations and equations

## Quick Reference

### Basic Scene Structure
```python
from manimlib import *

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

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

        # Or animate
        self.play(ShowCreation(circle))  # Note: ShowCreation, not Create

        # Wait
        self.wait(1)
```

### Render Command
```bash
# Render and preview
manimgl scene.py MyScene

# Interactive mode - drop into shell at line 15
manimgl scene.py MyScene -se 15

# Write to file
manimgl scene.py MyScene -w

# Low quality for testing
manimgl scene.py MyScene -l
```

### Key Differences from ManimCE

| Feature | ManimGL (3b1b) | Manim Community |
|---------|----------------|-----------------|
| Import | `from manimlib import *` | `from manim import *` |
| CLI | `manimgl` | `manim` |
| Math text | `Tex(R"\pi")` | `MathTex(r"\pi")` |
| Scene | `InteractiveScene` | `Scene` |
| Create anim | `ShowCreation` | `Create` |
| Camera | `self.frame` | `self.camera.frame` |
| Fix in frame | `mob.fix_in_frame()` | `self.add_fixed_in_frame_mobjects(mob)` |
| Package | `manimgl` (PyPI) | `manim` (PyPI) |

### Interactive Development Workflow

ManimGL's killer feature is interactive development:

```bash
# Start at line 20 with state preserved
manimgl scene.py MyScene -se 20
```

In interactive mode:
```python
# Copy code to clipboard, then run:
checkpoint_paste()           # Run with animations
checkpoint_paste(skip=True)  # Run instantly (no animations)
checkpoint_paste(record=True) # Record while running
```

### Camera Control (self.frame)

```python
# Get the camera frame
frame = self.frame

# Reorient in 3D (phi, theta, gamma, center, height)
frame.reorient(45, -30, 0, ORIGIN, 8)

# Animate camera movement
self.play(frame.animate.reorient(60, -45, 0))

# Fix mobjects to stay in screen space during 3D movement
title.fix_in_frame()
```

### LaTeX with Tex class

```python
# Use raw strings with capital R
formula = Tex(R"\int_0^1 x^2 \, dx = \frac{1}{3}")

# Color mapping with t2c
equation = Tex(
    R"E = mc^2",
    t2c={"E": BLUE, "m": GREEN, "c": YELLOW}
)

# Isolate substrings for animation
formula = Tex(R"\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}")
formula.set_color_by_tex("n", BLUE)
```

### Common Patterns

#### Embedding for debugging
```python
def construct(self):
    circle = Circle()
    self.play(ShowCreation(circle))
    self.embed()  # Drops into IPython shell here
```

#### Set floor plane for 3D
```python
self.set_floor_plane("xz")  # Makes xy the viewing plane
```

#### Backstroke for text readability
```python
text = Text("Label")
text.set_backstroke(BLACK, 5)  # Black outline behind text
```

### Installation

```bash
# Install ManimGL
pip install manimgl

# Check installation
manimgl --version
```

### Common Pitfalls to Avoid

1. **Version confusion** - Ensure you're using `manimgl`, not `manim` (community version)
2. **ShowCreation vs Create** - ManimGL uses `ShowCreation`, not `Create`
3. **Tex vs MathTex** - ManimGL uses `Tex` with capital R raw strings
4. **self.frame vs self.camera.frame** - ManimGL uses `self.frame` directly
5. **fix_in_frame()** - Call on the mobject, not the scene
6. **Interactive mode** - Use `-se` flag for interactive development
