#Python #3d #Programming #datascience #Machinelearning ## Python 3D: A Beginner's Guide
3D graphics are becoming increasingly popular, thanks to the rise of virtual reality (VR) and augmented reality (AR). If you're interested in creating 3D graphics, Python is a great option for you. Python is a powerful programming language that is easy to learn, and it has a wide range of libraries and tools that you can use to create 3D graphics.
In this guide, we will show you how to create 3D graphics in Python using the [Pyglet](https://pyglet.org/) library. Pyglet is a cross-platform library that makes it easy to create 2D and 3D graphics. It is designed to be lightweight and easy to use, making it a great choice for beginners.
We will start by creating a simple 3D cube. Then, we will learn how to add textures, lighting, and animation to our cube. By the end of this guide, you will have the skills you need to create your own 3D graphics in Python.
### Getting Started
The first thing you need to do is install the Pyglet library. You can do this by following the instructions on the [Pyglet website](https://pyglet.org/).
Once you have installed Pyglet, you can create a new project by creating a new file called `main.py`. In this file, we will import the Pyglet library and create a window that we can use to display our 3D graphics.
```python
import pyglet
window = pyglet.window.Window()
```
### Creating a Cube
Now that we have a window, we can start creating our 3D cube. We will start by creating a 3D mesh that represents the cube. A mesh is a collection of vertices, edges, and faces that define a 3D object.
We can create a mesh for our cube using the following code:
```python
vertices = [
(-1, -1, -1),
(1, -1, -1),
(1, 1, -1),
(-1, 1, -1),
(-1, -1, 1),
(1, -1, 1),
(1, 1, 1),
(-1, 1, 1),
]
indices = [
0, 1, 2,
2, 3, 0,
4, 5, 6,
6, 7, 4,
0, 4, 5,
5, 1, 0,
1, 5, 6,
6, 2, 1,
2, 6, 7,
7, 3, 2,
3, 7, 4,
4, 0, 3,
]
mesh = pyglet.graphics.Mesh(vertices, indices)
```
This code creates a mesh with 8 vertices and 12 indices. The vertices define the position of each point on the cube, and the indices define the order in which the vertices are connected to form the faces of the cube.
### Adding Textures
Now that we have a mesh for our cube, we can add a texture to it. A texture is a 2D image that is used to map onto a 3D object. This allows us to give our cube a realistic appearance.
We can add a texture to our cube using the following code:
```python
texture = pyglet.image.load('cube.png')
mesh.texture = texture
```
This code loads a texture from a file called `cube.png` and assigns it to the mesh. Now, when we render the cube, the texture will be applied to it.
### Adding Lighting
To make our cube look more realistic, we can add some lighting to it. We can do this by using the [Pyglet lighting system](
