Pycairo

In this course, you will use Python’s Pycairo library to draw complex shapes. So if you have an appetite for virtual reality, or game development, then this course will serve you well.

You will start with basic concepts like: What is the difference between pixel and vector graphics? After that, you will learn to make basic drawings and then you will move on to complex shapes. Throughout, you will cover important concepts like transform and state, working with text, gradients, and a whole lot more.

By the time you finish this course, you will have a powerful new library at your disposal, and you’ll be able to construct beautiful graphics that users will love.

Computer Graphics in Python and Pycairo

## Function curves
Sometimes, we might want to draw a curve based on a mathematical function. Here is an example of a function:

 y = f(x):

```
y = math.sin(10*x) * math.exp(-x/2)
```


This function is a **decaying sine wave**. It represents a simple damped oscillation.  An example of this is the sound created when we pluck a guitar string, which starts off loud and gradually fades away. Don’t worry too much about the details of the function. We are only using it because it looks quite nice. 

This is a graph of the function, created using Pycairo:
