We want you to view our design as something that has worked well for us in virtual globes, but as only one of a myriad approaches to renderer design. 1 The Need for a Renderer Given that APIs such as OpenGL and Direct3D are already an abstraction, it is natural to ask, why build a renderer layer in our engine at all? Aren’t these APIs sufficiently high level enough to use directly throughout our engine? Many small projects do scatter API calls throughout their code, but as projects get larger, it is important that they properly abstract the underlying API for many reasons: • Ease of development.

In code examples, angles are in radians because C# and GLSL functions expect radians. com/ Part I Fundamentals 2 Math Foundations At the heart of an accurately rendered virtual globe is an ellipsoidal representation of Earth. This chapter introduces the motivation and mathematics for such a representation, with a focus on building a reusable Ellipsoid class containing functions for computing surface normals, converting between coordinate systems, computing curves on an ellipsoid surface, and more.
