Chapter 13. Camera and Frustum
In this chapter, we will explore some rendering related functionality. We are going to explore creating a camera and controlling that camera to help us visualize the physics demos that we will create in the next chapter. This chapter will cover the following topics:
- Camera object
- Camera controls
- Frustum object
- Frustum from matrix
- Sphere in frustum
- Bounding Box in frustum
- Octree culling
- Picking
