In order to create dazzling real-time scenes, we must understand how 3D cameras work. Only then we will be able to control their properties and switch between multiple cameras to give life to our 3D models located in a 3D world.
The 3D cameras are both complex and powerful. Hence, we must reduce their complexity to keep things simple, and must be able to exploit their power without reading Pitagora's bookshelf.
In this chapter, we will learn everything we need to know about 3D cameras so that we can render our models in real time on a 2D screen from different angles. By reading it and following the exercises, we will learn to:
Understand how to work with the most important properties of 3D cameras
Control transformations applied to cameras and understand their effects on the rendered view
Prepare the cameras according to our scene needs
Work with many cameras with different parameters
Control the part of the 3D world rendered...
