OpenGL® Shading Language, Third Edition, extensively updated for OpenGL 3.1, is the experienced application programmer’s guide to writing shaders. Part reference, part tutorial, this book thoroughly explains the shift from fixed-functionality graphics hardware to the new era of programmable graphics hardware and the additions to the OpenGL API that support this programmability. With OpenGL and shaders written in the OpenGL Shading Language, applications can perform better, achieving stunning graphics effects by using the capabilities of both the visual processing unit and the central processing unit. In this book, you will find a detailed introduction to the OpenGL Shading Language (GLSL) and the new OpenGL function calls that support it. The text begins by describing the syntax and semantics of this high-level programming language. Once this foundation has been established, the book explores the creation and manipulation of shaders using new OpenGL function calls. OpenGL® Shading Language, Third Edition, includes updated descriptions for the language and all the GLSL entry points added though OpenGL 3.1, as well as updated chapters that discuss transformations, lighting, shadows, and surface characteristics. The third edition also features shaders that have been updated to OpenGL Shading Language Version 1.40 and their underlying algorithms, including Traditional OpenGL fixed functionality Stored textures and procedural textures Image-based lighting Lighting with spherical harmonics Ambient occlusion and shadow mapping Volume shadows using deferred lighting Ward’s BRDF model The color plate section illustrates the power and sophistication of the OpenGL Shading Language. The API Function Reference at the end of the book is an excellent guide to the API entry points that support the OpenGL Shading Language.
If you’re looking for a dose of wonder in your reading life, I recommend this beautiful book about the magic of fig trees."—Book Riot Over millions of years, fig trees have shaped our world, influenced our evolution, nourished our bodies and fed our imaginations. And as author and ecologist Mike Shanahan proclaims, “The best could be yet to come.” Gods, Wasps and Stranglers weaves together the mythology, history and ecology of one of the world’s most fascinating—and diverse—groups of plants, from their starring role in every major religion to their potential to restore rainforests, halt the loss of rare and endangered species and even limit climate change. In this lively and joyous book, Shanahan recounts the epic journeys of tiny fig wasps, whose eighty-million-year-old relationship with fig trees has helped them sustain more species of birds and mammals than any other trees; the curious habits of fig-dependent rhinoceros hornbills; figs’ connection to Krishna and Buddha, Jesus and Muhammad; and even their importance to Kenya’s struggle for independence. Ultimately, Gods, Wasps and Stranglers is a story about humanity’s relationship with nature, one that is as relevant to our future as it is to our past.
Irresistible" - Literary Review Fig trees have affected humanity in profound but little-known ways: they are wish-fulfillers, rainforest royalty, more precious than gold. Ladders to Heaven tells their incredible story. They fed our pre-human ancestors, influenced diverse cultures and played a key role in the birth of civilisation. More recently, they helped restore life after Krakatoa's catastrophic eruption and proved instrumental in Kenya's struggle for independence. Figs now sustain more species of bird and mammal than any other fruit – in a time of falling trees and rising temperatures, they offer hope. Theirs is a story about humanity's relationship with nature, as relevant to our past as it is to our future.
