A spirograph is a **geometric shape** formed by **tracing** a point a distance from the center of a **circle** as it rolls along the **inside or outside** of a **fixed circle**

The combination of these two circles creates a **unique path**, resulting in a captivating and intricate pattern. With the help of the Spyrograph library, we can create a **wide variety** of these patterns using just a few **simple parameters**

The `animate` method in the Spyrograph library is a **powerful tool** for **generating and visualizing** spirograph patterns. By providing a **range of values** for the **input parameters**, we can create a sequence of spirographs that smoothly transition from one to another, giving the illusion of a continuous animation. This method takes care of all the drawing and updating, allowing us to **focus** on the creative aspect of designing our spirograph animations.

Let's look at a **simple example** of how to use the `animate` method to create a spirograph animation:

```python
from spyrograph import Hypotrochoid
import numpy as np

Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 75, .05),
    d=33,
    thetas=np.arange(0,100, .1),
    frame_pause=.02
)
```

In this example, we call the `animate` method on the `Hypotrochoid` class with our chosen parameter values. This will generate a sequence of spirograph animations, each with a **different radius** `r` while keeping the other parameters **constant**

The `animate` method is highly **versatile**, allowing us to **customize** the appearance of our animations by adjusting various parameters such as the `color`, `width`, and `screen_size`. This flexibility enables us to create a wide range of visually appealing spirograph animations that cater to our artistic preferences

In the following sections, we'll dive deeper into the `animate` method, exploring its various customization options and providing tips and tricks to help us master the art of spirograph animation

## Customizing our spirograph animations <a src="#customizing-our-spirograph-animations"></a>
One of the most exciting aspects of using the `animate` method is the ability to customize and personalize our spirograph animations

With a **plethora of configuration options** at our fingertips, we can create unique patterns that resonate with our artistic vision. In this section, we'll explore some of the ways you can **customize** our animations using the `animate` method

### Varying the circle radii and tracing point distance <a src="#varying-the-circle-radii-and-tracing-point-distance"></a>
The **primary driving factors** behind the generated patterns are the **radii** of the fixed and rolling circles (`R` and `r`, respectively) and the **distance** of the tracing point from the rolling circle (`d`). By altering these parameters, we can create a wide array of stunning spirograph designs

For example, we can experiment with different combinations of `R`, `r`, and `d` to find the **perfect balance** that produces intricate and mesmerizing patterns

#### Varying the radius of the fixed circle: <a src="#varying-the-radius-of-the-fixed-circle"></a>
```python
Hypotrochoid.animate(
    R=np.arange(201*3, 215*3, .1*3),
    r=179*3,
    d=79*3,
    thetas=np.arange(0,50, .1),
    frame_pause=.08
)
```

#### Varying the radius of the rolling circle: <a src="#varying-the-radius-of-the-rolling-circle"></a>
```python
Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 60, .025),
    d=33,
    thetas=np.arange(0,100, .1),
    frame_pause=.08
)
```

#### Varying the distance from the rolling circle: <a src="#varying-the-distance-from-the-rolling-circle"></a>
```python
Hypotrochoid.animate(
    R=300,
    r=113,
    d=np.arange(113, 140, .5),
    thetas=np.arange(0,50, .1),
    frame_pause=.08
)
```

### Color and line width customization <a src="#color-and-line-width-customization"></a>
The `animate` method also allows us to customize the `color` and `width` of the traced lines. By changing the `color` and `width` parameters, we can achieve different visual effects and styles

Whether we want a **subtle, delicate** design or a **bold, striking** pattern, adjusting these parameters gives us the creative freedom to bring our vision to life

```python
Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 60, .025),
    d=33,
    thetas=np.arange(0,100, .1),
    frame_pause=.08,
    color="red",
    width=5
)
```

![An animation of lines rotating creating beautiful geometric patterns colored in red with a thicker width](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4quwyctpvkmpv45eiqka.gif)

### Control over theta tange and step <a src="#control-over-theta-tange-and-step"></a>
Another powerful customization option is the ability to define the **range of theta values** and the incremental step between them

By modifying either the `thetas` argument or the `theta_start`, `theta_stop`, and `theta_step` parameters, we can control the **precision and smoothness** of the traced lines

**Smaller theta steps** lead to **smoother curves**, while **larger steps** create more **segmented patterns**, offering yet another avenue for personalizations

#### Small theta step <a src="#small-theta-step"></a>
```python
Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 60, .025),
    d=33,
    thetas=np.arange(0,100, .1),
    frame_pause=.08
)
```

#### Large theta step <a src="#large-theta-step"></a>
```python
Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 60, .025),
    d=33,
    thetas=np.arange(0,100, 1),
    frame_pause=.08
)
```

### Background and screen customization <a src="#background-and-screen-customization"></a>
The `animate` method enables us to customize the **background color** and **screen size** of our animations through the `screen_color` and `screen_size` parameters

By adjusting these settings, we can create a visual environment that complements our spirograph design and enhances the overall aesthetic appeal of our animations

```python
Hypotrochoid.animate(
    R=307,
    r=np.arange(57, 60, .025),
    d=33,
    thetas=np.arange(0,100, 1),
    frame_pause=.08,
    color="white",
    screen_color="black"
)
```
