# Examples
Contents of `example.py`.
Do not forget to import Manim Slides and Manim or ManimGL:
```python
from manim import *
from manim_slides import Slide, ThreeDSlide
```
or
```python
from manimlib import *
from manim_slides import Slide, ThreeDSlide
```
Then, each presentation, named `SCENE`, was generated with those two commands:
```bash
manim example.py SCENE # or manimgl example SCENE
manim-slides convert SCENE scene.html -ccontrols=true
```
where `-ccontrols=true` indicates that we want to display the blue navigation arrows.
## Basic Example
Basic example from quickstart.
```{eval-rst}
.. literalinclude:: ../../../example.py
:language: python
:linenos:
:pyobject: BasicExample
```
## 3D Example
Example using 3D camera. As Manim and ManimGL handle 3D differently, definitions are slightly different.
### With Manim
```{eval-rst}
.. literalinclude:: ../../../example.py
:language: python
:linenos:
:dedent: 4
:start-after: [manim-3d]
:end-before: [manim-3d]
```
### With ManimGL
```{eval-rst}
.. literalinclude:: ../../../example.py
:language: python
:linenos:
:dedent: 4
:start-after: [manimgl-3d]
:end-before: [manimgl-3d]
```
## Subclass Custom Scenes
For compatibility reasons, Manim Slides only provides subclasses for
`Scene` and `ThreeDScene`.
However, subclassing other scene classes is totally possible,
and very simple to do actually!
[For example](https://github.com/jeertmans/manim-slides/discussions/185),
you can subclass the `MovingCameraScene` class from `manim`
with the following code:
```{code-block} python
:linenos:
from manim import *
from manim_slides import Slide
class MovingCameraSlide(Slide, MovingCameraScene):
pass
```
And later use this class anywhere in your code:
```{code-block} python
:linenos:
class SubclassExample(MovingCameraSlide):
def construct(self):
eq1 = MathTex("x", "=", "1")
eq2 = MathTex("x", "=", "2")
self.play(Write(eq1))
self.next_slide()
self.play(
TransformMatchingTex(eq1, eq2),
self.camera.frame.animate.scale(0.5)
)
self.wait()
```
:::{note}
If you do not plan to reuse `MovingCameraSlide` more than once, then you can
directly write the `construct` method in the body of `MovingCameraSlide`.

## Advanced Example
A more advanced example is `ConvertExample`, which is used as demo slide and tutorial.
```{eval-rst}
.. literalinclude:: ../../../example.py
:language: python
:linenos:
:pyobject: ConvertExample
```
