Chapter 13. Camera Specifications and Transformations
13.1. Introduction
In this chapter, we briefly discuss camera specifications, which you already encountered in Chapter 6. Recall that we specified a camera in WPF in code like that shown below:
1 <PerspectiveCamera 2 Position="57, 247, 41" 3 LookDirection="-0.2, 0, -0.9" 4 UpDirection="0, 1, 0" 5 NearPlaneDistance="0.02" FarPlaneDistance="1000" 6 FieldOfView="45" 7 />
From such a specification, we will create a sequence of transformations that will transform the world coordinates of a point on some model to so-called “camera coordinates,” and from there to image coordinates. We’ll do so by repeatedly using ...
