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. 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.

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. 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.

Welcome to ARToolworks. Augmented Reality (Vuforia) Wikitude - World's leading Augmented Reality SDK. Panorama 360 iPod Touch & iPhone. Introduction PanoramaGL library is the first open source library in the world to see panoramic views on the iPod Touch 1G, 2G, 3G and iPhone EDGE, 3G and 3GS. SVN and source code in Created by Javier Baez - Visit Ecuador Team Important Note: Please add the credits in their projects when using the library. Background The supported features in version 0.1 Beta are: Using the Code To create a simple panoramic image viewer for the iPhone with PanoramaGL library, you must perform the following steps: 1.
Open XCode Go to "File -> New Project -> iPhone OS -> Application -> View-based Application" Click on "Choose" button and Save the project as "HelloPanorama" 2. Download "PanoramaGL" library (Parent project folder) Decompress "PanoramaGL" library (double click on zip file) Go to menu "Project -> Edit Active Target 'HelloPanorama'" Go to "General" Tab Click on "+" button in the "Linked Library Section" Click on "Add Other" button and find "PanoramaGL" project 3. 4.
