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.

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. Magnetism. Calculate distance and bearing between two Latitude/Longitude points using Haversine formula in JavaScript. This page presents a variety of calculations for latitude/longitude points, with the formulæ and code fragments for implementing them.

All these formulæ are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) – which is accurate enough* for most purposes… [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3% – see notes for further details]. Distance This uses the ‘haversine’ formula to calculate the great-circle distance between two points – that is, the shortest distance over the earth’s surface – giving an ‘as-the-crow-flies’ distance between the points (ignoring any hills, of course!).

The haversine formula1 ‘remains particularly well-conditioned for numerical computation even at small distances’ – unlike calculations based on the spherical law of cosines.

Human Interface Technology Laboratory. HITLab NZ. Panorama Mapping and Tracking. Panorama created in real-time on the mobile phone.

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. Welcome to ARToolworks. Augmented Reality (Vuforia) Wikitude - World's leading Augmented Reality SDK.
