OpenGL ES 2.0 for iOS, Chapter 3 - Fundamentals of 3D Programming. Before we start writing code, we need to go over some of the basics concept and algorithms used in 3D programming.

OpenGL ES 2.0 for iOS, Chapter 3 - Fundamentals of 3D Programming

Essentially, we need to make sure we're all speaking the same language. In this chapter, we're going to discuss some of the most basic and fundamental concepts underlying the use of OpenGL ES 2.0, as well as some of the data structures and algorithms that we'll need to create and manipulate virtual three-dimensional objects. We'll talk about what vertices, vectors, polygons, and colors are and how they are represented in OpenGL ES.

We'll also look at some of the math that you'll need to perform on each of them. The math involved in computer graphics can be mind-numbingly complex at times, but don't worry, we're going to ease into the math slowly. The Cartesian Coordinate System The first thing you need to understand before doing any 3D graphics programming is how locations are represented in a three-dimensional world. Well, they're OpenGL units. Vertices Wait… struct? Vectors. Magnetism. Calculate distance and bearing between two Latitude/Longitude points using Haversine formula in JavaScript.

Panorama Mapping and Tracking

Summary Tracking for outdoor Augmented Reality (AR) applications has very demanding requirements: It must deliver an accurate registration with respect to a given coordinate system, be robust and run in real time. Despite recent improvements, outdoor tracking still remains a difficult problem. We implemented a system for the online creation and simultaneous tracking of panoramas. Our system uses a natural feature mapping and tracking method, which is sufficiently efficient and robust to allow 3 degrees of freedom tracking on mobile phones.
