This Wrox Blox will guide you through the world of 3D programming and give you solid knowledge and a foundation in game programming using Microsoft's XNA Framework. You will learn the fundamentals from 3D mathematics to model animation, including all the subjects needed to start developing 3D games, such as how to position objects in 3D space, handle collision detection, control the game camera, and understand the basics of shaders — special programs that execute on the graphics processor. Also covered are how to extend the XNA Content Pipeline to read and use model skeletal animation, and also load and play back timeline animation data created in 3D modeling tools. 3D concepts and systems can seem like a foreign language when you're a beginner. And not knowing the lingo can make it hard to know what terms to search for to solve a problem. This Wrox Blox will give you all the tools you need to build your own 3D game.

More people were killed by smallpox during the twentieth century--over 300 million--than by all of the wars of that period combined. In 1918 and 1919, influenza virus claimed over 50 million lives. A century later, influenza is poised to return, ongoing plagues of HIV/AIDS and hepatitis infect millions, and Ebola, Zika, and West Nile viruses cause new concern and panic. The overlapping histories of humans and viruses are ancient. Earliest cities became both the cradle of civilization and breeding grounds for the first viral epidemics. This overlap is the focus of virologist/immunologist Michael Oldstone in Viruses, Plagues and History. Oldstone explains principles of viruses and epidemics while recounting stories of viruses and their impact on human history. This fully updated second edition includes engrossing new chapters on hepatitis, Zika, and contemporary threats such as the possible return of a catastrophic influenza, and the impact of fear of autism on vaccination efforts. This is a fascinating panorama of humankind's longstanding conflict with unseen viral enemies, both human successes--such as control of poliomyelitis, measles, smallpox and yellow fever, and continued dangers--such as HIV and Ebola. Impeccably researched and accessibly written, Viruses, Plagues and History will fascinate all with an interest in how viral illnesses alter the course of human history.
Viruses are the most abundant biological entities on Earth, and arguably the most successful. They are not technically alive, but—as infectious vehicles of genetic information—they have a remarkable capacity to invade, replicate, and evolve within living cells. Synthesizing a large body of recent research, Michael Cordingley goes beyond our familiarity with viral infections to show how viruses spur evolutionary change in their hosts, shape global ecosystems, and influence every domain of life. In the last few decades, research has revealed that viruses are fundamental to the photosynthetic capacity of the world’s oceans and the composition of the human microbiome. Perhaps most fascinating, viruses are now recognized as remarkable engines of the genetic innovation that fuels natural selection and catalyzes evolution in all domains of life. Viruses have coevolved with their hosts since the beginning of life on our planet and are part of the evolutionary legacy of every species that has ever lived. Cordingley explains how viruses are responsible for the creation of many feared bacterial diseases and the emergence of newly pathogenic and drug-resistant strains. And as more and more viruses jump to humans from other animals, new epidemics of viral disease will threaten global society. But Cordingley shows that we can adapt, relying on our evolved cognitive and cultural capacities to limit the consequences of viral infections. Piecing together the story of viruses’ major role within and beyond human disease, Viruses creates a valuable roadmap through the rapidly expanding terrain of virology.
