Implementing collision detection and response on a transform feedback-based cloth model

In this recipe, we will build on top of the previous recipe and add collision detection and response to the cloth model.

Getting ready

The code for this recipe is contained in the Chapter8/TransformFeedbackClothCollision directory. For this recipe, the setup code and rendering code remains the same as in the previous recipe. The only change is the addition of the ellipsoid/sphere collision code.

How to do it…

Let us start this recipe by following these simple steps:

1. Generate the geometry and topology for a piece of cloth by creating a set of points and their connectivity. Bind this data to a buffer object as in the previous recipe.
2. Set up a pair of vertex array objects ...
