Cinder Creative Coding Cookbook

Overview of this book

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, interactive applications."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 applications using Cinder.With recipes that include drawing in 3D, image processing, and sensing and tracking in real-time from camera input, the book will teach you how to develop interesting applications."Cinder Creative Coding Cookbook" will give you the necessary knowledge to start creating projects with Cinder that use animations and advanced visuals.

Setting up a GUI for tweaking parameters


Graphical User Interface (GUI) is often required for controlling and tuning your Cinder application. In many cases, you spend more time tweaking the application parameters to achieve the desired result than writing the code. It is true especially when you are working on some generative graphics.

Cinder provides a convenient and easy-to-use GUI via the InterfaceGl class.

Getting ready

To make the InterfaceGl class available in your Cinder application, all you have to do is include one header file.

#include "cinder/params/Params.h"

How to do it…

Follow the steps given here to add a GUI to your Cinder application.

  1. Let's start with preparing different types of variables within our main class, which we will be manipulating using the GUI.

    float mObjSize;
    Quatf mObjOrientation;
    Vec3f mLightDirection;
    ColorA mColor;
  2. Next, declare the InterfaceGl class member like this:

    params::InterfaceGl mParams;
  3. Now we move to the setup method and initialize our GUI window passing...
