Computer Graphics from Scratch
Computer Graphics from Scratch demystifies the algorithms used in modern graphics software and guides beginners through building photorealistic 3D renders. Computer graphics programming books are often math-heavy and intimidating for newcomers. Not this one. Computer Graphics from Scratch takes a simpler approach by keeping the math to a minimum and focusing on only one aspect of computer graphics, 3D rendering. You’ll build two complete, fully functional renderers: a raytracer, which simulates rays of light as they bounce off objects, and a rasterizer, which converts 3D models into 2D pixels. As you progress you’ll learn how to create realistic reflections and shadows, and how to render a scene from any point of view. Pseudocode examples throughout make it easy to write your renderers in any language, and links to live JavaScript demos of each algorithm invite you to explore further on your own. Learn how to: Use perspective projection to draw 3D objects on a 2D plane Simulate the way rays of light interact with surfaces Add mirror-like reflections and cast shadows to objects Render a scene from any camera position using clipping planes Use flat, Gouraud, and Phong shading to mimic real surface lighting Paint texture details onto basic shapes to create realistic-looking objects Whether you’re an aspiring graphics engineer or a novice programmer curious about how graphics algorithms work, Gabriel Gambetta’s simple, clear explanations will quickly put computer graphics concepts and rendering techniques within your reach. All you need is basic coding knowledge and high school math. Computer Graphics from Scratch will cover the rest.
A Light from the Shadows

For thousands of years, spiritual and religious practitioners in India, Tibet, and elsewhere have made special use of prayer bead garlands called "mala" in chanting the divine Name and other words of power. Even today, these sacred objects are believed to aid the seeker in establishing a rhythmic centering of consciousness, reconnecting him or her with the energies believed to sustain the natural world. In the spirit of this same meditative tradition, 108 original poetic insights form the body of this powerful and nuanced exploration of individual and cosmic identity, acceptance, and psychological freedom. With a thematic structure corresponding to the seven major "chakras" or energy centers of the human body, "A Light from the Shadows" guides the reader on a journey of personal revelation: from an introduction to personal mythology and its power to shape our life experience; to the role of suffering and love in the creation of identity; to the subjective nature of time, separateness, and linear causality. This unique and engaging collection of quotable wisdom is the perfect companion gift, not just for the spiritual seeker or adept, but for anyone interested in taking his or her first step towards a larger understanding of the universe and our place in it.

Reflections and Shadows
We all grew up in Saul Steinberg’s America, a place he envisioned for us in his drawings and cartoons for The New Yorker—none more famous than his iconic image of a New Yorker’s view of the world. In this eccentric and unpredictable memoir, one of the twentieth century’s most intellectually nimble artists shares his view of the world, of America and his place in it. A Romanian by birth, restless by inclination, Steinberg lived a peripatetic existence. In Reflections and Shadows, he introduces us to his family—his uncle Moritz, a sign painter, and his father (also Moritz), a bookbinder whose small factory produced cardboard boxes and ribbons for funeral wreaths. He tells us how he dodged the police in fascist Italy in 1940 and how he came to America, where he became a citizen, an officer in the U.S. Navy, and the foremost visionary satirist of his time. No one has depicted America with all its strengths and foibles more enduringly than Saul Steinberg. In this playful meditation, based on a series of interviews with Aldo Buzzi that has never before been published in English, and interwoven with more than a dozen drawings, Steinberg delivers a laconic hymn to America: its baseball, its diners, and its exhibitionism. “It is stinginess,” Steinberg writes, speaking of his art and method, “that holds us back.” But he had none of that: the personality that emerges from these pages is capacious, acutely discriminating, full of serendipitous curiosities, and consistently engaging.
