Master the math behind CAD, game engines, GIS, and more! This hands-on book teaches you the geometry used to create simulations, 3D prints, and other models of the physical world.

In

Geometry for Programmers

you will learn how to:

Speak the language of applied geometry

Compose geometric transformations economically

Craft custom splines for efficient curves and surface generation

Pick and implement the right geometric transformations

Confidently use important algorithms that operate on triangle meshes, distance functions, and voxels

Geometry for Programmers

guides you through the math behind graphics and modeling tools. It’s full of practical examples and clear explanations that make sense even if you don’t have a background in advanced math. You’ll learn how basic geometry can help you avoid code layering and repetition, and even how to drive down cloud hosting costs with more efficient runtimes. Cheerful language, charts, illustrations, equations, and Python code help make geometry instantly relevant to your daily work as a developer.

About the Technology

Geometry is at the heart of game engines, robotics, computer-aided design, GIS, and image processing. This book draws back what is for some a mathematical curtain, giving them insight and control over this central tool. You’ll quickly see how a little geometry can help you design realistic simulations, translate the physical world into code, and even reduce your cloud services bill by improving the efficiency of graphics-intensive applications.

About the Book

Geometry for Programmers

is both practical and entertaining. Fun illustrations and engaging examples show you how to apply geometry to real programming problems, like changing a scan into a CAD model or developing 3D printing contours from a parametric function. And don't worry if you aren't a math expert. There’s no heavy theory, and you’ll learn how to offload most equations to the SymPy computer algebra system.

What’s Inside

Speak the language of applied geometry

Compose geometric transformations economically

Craft custom splines for efficient curves and surface generation

Confidently use geometry algorithms
