The concept of the earth as a sphere has been around for centuries, emerging around the time of Pythagoras in the sixth century BC, and eventually becoming dominant as other thinkers of the ancient world, including Plato and Aristotle, accepted the idea. The first record of an actual globe being made is found in verse, written by the poet Aratus of Soli, who describes a celestial sphere of the stars by Greek astronomer Eudoxus of Cnidus (ca. 408–355 BC). The oldest surviving globe—a celestial globe held up by Atlas’s shoulders—dates back to 150 AD, but in the West, globes were not made again for about a thousand years. It was not until the fifteenth century that terrestrial globes gained importance, culminating when German geographer Martin Behaim created what is thought to be the oldest surviving terrestrial globe. In Globes: 400 Years of Exploration, Navigation, and Power, Sylvia Sumira, beginning with Behaim’s globe, offers a authoritative and striking illustrated history of the subsequent four hundred years of globe making. Showcasing the impressive collection of globes held by the British Library, Sumira traces the inception and progression of globes during the period in which they were most widely used—from the late fifteenth century to the late nineteenth century—shedding light on their purpose, function, influence, and manufacture, as well as the cartographers, printers, and instrument makers who created them. She takes readers on a chronological journey around the world to examine a wide variety of globes, from those of the Renaissance that demonstrated a renewed interest in classical thinkers; to those of James Wilson, the first successful commercial globe maker in America; to those mass-produced in Boston and New York beginning in the 1800s. Along the way, Sumira not only details the historical significance of each globe, but also pays special attention to their materials and methods of manufacture and how these evolved over the centuries. A stunning and accessible guide to one of the great tools of human exploration, Globes will appeal to historians, collectors, and anyone who has ever examined this classroom accessory and wondered when, why, and how they came to be made.

From medieval globes made when much of the world was unexplored to the huge, decorative examples made for the princely courts of Renaissance Europe, this book celebrates the art and history of the globe, focusing on the 400 years when the printed globe - as navigational tool, scientific instrument and powerful status symbol - occupied an important place in the history of European exploration.

When the Little Prince and Fox arrive on planet Voltaine, they learn of a strange creature that only comes out at night and can turn people to stone, but it is unclear if it is real or just a ploy by the streetlamp seller.

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 applications like Google Earth and NASA World Wind. The content is also useful for general graphics and games, especially planet and massive-world engines. With pragmatic advice throughout, it is essential reading for practitioners, researchers, and hobbyists in these areas, and can be used as a text for a special topics course in computer graphics. Topics covered include: Rendering globes, planet-sized terrain, and vector data Multithread resource management Out-of-core algorithms Shader-based renderer design
