Virtual globes are known for their ability to render massive real-world ter- rain, imagery, and vector datasets. The servers providing data to virtual globes such as. 10 Exploiting Parallelism in Resource Preparation. Parallelism Everywhere Task-Level Parallelism in Virtual Globes. 3D Engine Design for Virtual Globes provides a fine guide to engine design and algorithms for virtual globe applications such as Google Earth packed with.

3D Engine Design for Virtual Globes has 2 repositories available. Follow their code on GitHub. Jul 3, 3D Engine Design for Virtual Globes is a book by Patrick Cozzi and Kevin Ring describing the essential techniques and algorithms used for the. Supported with code examples and the authors' real-world experience, this book offers the first guide to engine design and rendering algorithms for virtual globe.

Patrick Cozzi and Kevin Ring, the authors of this nice book, have done a very good job and from now, I keep it on my desk, with my other OpenGL books. A great resource!

This is the first book of that kind. It covers all important aspects of large terrain rendering and presents excellent foundation for further research.

An open source virtual globe rendering engine for 3D applications: NASA World Wind

The full source code is also available for download. In virtual globes, we usually have a really big image that we want to wrap around an ellipsoid or sphere with displacements for terrain.

The image is recursively divided into four, quad-tree style and streamed using out-of-core rendering.

The book gives an overview of some state-of-the-art algorithms, but the implementation of Google Earth is still and probably will be a proprietary. If I remember correctly, Rage uses some kind of ray-casting for terrain rendering….

Thanks Patrick!

This link is also available from your blog-site. Suffice it to say, the latest implementations may have changed significantly.

And even my explanations are going to be so broad and potentially out-dated that no one should use this article as the basis for anything except intellectual curiosity and understanding.

I just wanted to say that the book is not about Google Earth, but gives very comprehensive overview of techniques used to implement virtual globes. I am seriously considering downloading this book or putting in a request for our university library to order it. There are some really cool public domain high resolution DEMs and aerial photography for parts of New Zealand that I have always wanted to convert into a cool demo.

Also my current project on modelling cell phone networks would look really cool overlaid onto a 3D map…. It can display multi-resolution imagery, terrain and geometric data using multiple supported formats. Layers allow shapes in 2D, 3D and also user-defined elevation data. Also available in the API as layers are utilities like the compass layer, graticules, coordinates display and view controls.

View controls allow users to navigate in 3D using zoom, panning and tilting of the view in different directions. Also, new utilities are about to be added to the JavaScript API distribution for on-screen measurements, calculation of line-of-sight, creation of analytic surfaces and subsurface visualization support.

The Navigator is responsible for converting user actions to manipulations of the globe. It monitors mouse events and user gestures and translates them to pan, zoom or tilt operations on the globe. The Navigator can also be driven by the application to change the viewpoint to a particular location or to set its tilt and heading.

The Navigator is an object automatically integrated into each WorldWindow, allowing interacting with the globe to get all the information about its position. Developers can customize mouse movements and gestures to navigate the globe in different ways.

The Navigator can also be controlled by mobile devices and can be personalized to assign any mobile gesture to a particular action in the globe. Among the features there are also geocoders that permit discovery of geographic locations from a query string.

Thanks to this geocoder, it is possible to retrieve information about a city, area or location from its name or coordinates and then show all the desired information in the globe. NASA Web World Wind contains several other objects; most of them run behind the scenes, so programmers are not required to interact with them. As a result it is quite easy to extend the features already implemented or even create new ones.

It is designed to be extensible; adding functionality is simple and easy to do by extending existing modules or linking new tools as plug-ins. Results and discussion Since its release as open source in , NASA World Wind attracts a large number of contributions from the open source community.

The powerful modular architecture of NASA World Wind attracted improvements to the core functionalities, implementation of add-ons, delivery of high-resolution data, and outright development of GIS solutions.

Bell et al. What is reported is, obviously, a very small subset of many excellent applications developed by software engineers, students and professional teams from a large international community. We attempt to represent a range of different scopes and fields: multi-dimensional data viewers, collaborative solutions, cultural heritage representations, dissemination of science data and access to historical datasets from open data services.

The system is composed of two parts Fig.Careful attention has been ]. Product pricing will be adjusted to match the corresponding currency. This API is being enriched with functionalities from the Java version.

For example, users can access the enor- a list is visited sequentially, until a server is reached that to- mous amount of available internet data layers by means of tally covers the bounding box of the tile. Although this technology is not C for specific classes in iOS, Java for Android devices, included for desktop browsers, our globe web version can and JavaScript for the web version.
