Preface
Cinder is one of the most exciting frameworks available for creative coding. It is developed in C++ for increased performance and allows for the fast creation of visually complex and interactive applications. The big advantage of Cinder is that it can target many platforms such as Mac, Windows, and iOS with the exact same code.
Cinder Creative Coding Cookbook will show you how to develop interactive and visually dynamic applications using simple-to-follow recipes.
You will learn how to use multimedia content, draw generative graphics in 2D and 3D, and animate them in compelling ways.
Beginning with creating simple projects with Cinder, you will use multimedia, create animations, and interact with the user.
From animation with particles to using video, audio, and images, the reader will gain a broad knowledge of creating creative applications using Cinder.
With recipes that include drawing in 3D, image processing, and sensing and tracking in real-time from camera input, this book will teach you how to develop interactive applications that can be run on a desktop computer, mobile device, or be a part of an interactive installation.
This book will give you the necessary knowledge to start creating projects with Cinder that use animations and advanced visuals.

Chapter 1. Getting Started
In this chapter we will cover:
Introduction
In this chapter we'll learn the fundamentals of creating applications using Cinder.
We'll start by creating different types of applications on the different platforms that Cinder supports using a powerful tool called TinderBox.
We'll cover the basic structure of an application and see how to respond to user input events.
Finally, we will learn how to use resources on Windows and Mac.
Creating a project for a basic application
In this recipe, we'll learn how to create a project for a basic desktop application for Windows and Mac OSX.
Getting ready
Projects can be created using a powerful tool called TinderBox. TinderBox comes bundled in your Cinder download and contains templates for creating projects for different applications for both Microsoft Visual C++ 2010 and OSX Xcode.
To find Tinderbox, go to your Cinder folder, inside which you will find a folder named tools with, TinderBox application in it.
The first time you open TinderBox, you'll be asked to specify the folder where you installed Cinder. You'll need to do this only the first time you open TinderBox. If you need to redefine the location of Cinder installation, you can do so by selecting the File menu and then Preferences on Windows or selecting the TinderBox menu and then Preferences on OS X.
How to do it…
We'll use TinderBox, a utility tool that comes bundled with Cinder that allows for the easy creation of projects. Perform the following steps to create a project for a basic application:
How it works...
TinderBox will create the selected projects for the chosen platforms (Visual C++ 2010 and OS X Xcode) and create references to the compiled Cinder library. It will also create the application's class as a subclass of ci::app::AppBasic. It will also create some sample code with a basic example to help you get started.
There's more...
Your project name and naming prefix will be, by default, the name of the folder in which the project is being created. You can edit this if you want, but always make sure both Project Name and Naming Prefix fields do not have spaces as you might get errors.
The naming prefix will be used to name your application's class by adding the App suffix. For example, if you set your Naming Prefix field as MyCinderTest, your application's class will be MyCinderTestApp.
Creating a project for a screensaver application
In this recipe, we will learn how to create a project for a desktop screensaver for both Windows and Mac OS X.
Getting ready
To get ready with TinderBox, please refer to the Getting ready section of the previous Creating a project for a basic application recipe.
How to do it…
We'll use TinderBox, a utility tool that comes bundled with Cinder that allows easy creation of projects. Perform the following steps to create a project for a screensaver application:
How it works...
TinderBox will create both a project for you and link it against the compiled Cinder library. It will also create the application's class and make it a subclass of ci::app::AppScreenSaver, which is the class with all the basic functionality for a screensaver application. It will also create some sample code with a basic example to help you get started.
Creating a project for an iOS touch application
In this recipe, we'll learn how to create a project for an application that runs on iOS devices such as iPhone and iPad.
Getting ready
To get ready with TinderBox, please refer to the Getting ready section of the Creating a project for a basic application recipe.
Please note that the iOS touch application will only work on iOS devices such as iPhones and iPads, and that the projects created with TinderBox will be for OSX Xcode only.
How to do it…
We'll use TinderBox, a utility tool that comes bundled with Cinder that allows easy creation of projects. Perform the following steps to create a project for an iOS touch application:
How it works...
TinderBox will create an OS X Xcode project and create the references to link against the compiled Cinder library. It will also create the application's class as a subclass of ci::app::AppCocoaTouch, which is the class with all the basic functionality for a screensaver application. It will also create some sample code with a basic example to help you get started.
This application is built on top of Apple's Cocoa Touch framework to create iOS applications.
Responding to key input
A Cinder application can respond to key events through several callbacks.
The available callbacks that get called by keyboard interaction are listed in the following table:
Method
Usage
keyDown
