Creating a cloth simulation

In this recipe we will learn how to simulate cloth by creating a grid of particles connected by springs.

Getting Ready

In this recipe, we will be using the particle system described in the recipe Creating a particle system in 2D from Chapter 5, Building Particle Systems.

We will also be using the Springs class created in the recipe Creating springs from Chapter 5, Building Particle Systems.

So, you will need to add the following files to your project:

• Particle.h

• ParticleSystem.h

• Spring.h

• Spring.cpp

How to do it…

We will create a grid of particles connected with springs to create a cloth simulation.

1. Include the particle system file in your project by adding the following code on top of your source file:

   #include "ParticleSystem.h"

2. Add the using statements before the application class declaration as shown in the following code:

   using namespace ci;
   using namespace ci::app;
   using namespace std;

3. Create an instance of a ParticleSystem object and member variables to store the top corners...
