Raspberry Pi for Python Programmers Cookbook - Second Edition

Overview of this book

Raspberry Pi cookbook for Python Programmers is a practical guide for getting the most out of this little computer. This book begins by guiding you through setting up the Raspberry Pi, performing tasks using Python 3 and introduces the first steps to interface with electronics. As you work through each chapter you will build up your skills and knowledge and apply them as you progress throughout the book, delving further and further into the unique abilities and features of the Raspberry Pi. Later, you will learn how to automate tasks by accessing files, build applications using the popular Tkinter library and create games by controlling graphics on screen. You will harness the power of the built-in graphics processor by using Pi3D to generate your own high quality 3D graphics and environments. Connect directly to the Raspberry Pi’s hardware pins to control electronics from switching on LEDs and responding to push buttons right through to driving motors and servos. Learn how to monitor sensors to gather real life data and to use it to control other devices, and view the results over the Internet. Apply what you have learnt by creating your own Pi-Rover or Pi-Hexipod robots. Finally, we will explore using many of the purpose built add-ons available for the Raspberry Pi, as well as interfacing with common household devices in new ways.

Creating and importing 3D models


Creating complex shapes directly from code can often be cumbersome and time consuming. Fortunately, it is possible to import prebuilt models into your 3D space.

It is even possible to use graphical 3D modeling programs to generate models and then export them as a suitable format for you to use. This example produces a Newell Teapot in the Raspberry Pi theme, as shown in the following screenshot:

Getting ready

We shall use 3D models of a teapot (both teapot.obj and teapot.mdl) located in pi3d\models.

Note

Modeling a teapot is the traditional 3D equivalent of displaying Hello World. Computer graphics researcher Martin Newell first created the Newell Teapot in 1975 as a basic test model for his work. The Newell Teapot soon became the standard model to quickly check if a 3D rendering system is working correctly (it even appeared in Toy Story and a 3D episode of The Simpsons).

Other models are available in the pi3d\models directory (monkey...
