Ray Tracing Gems: High-Quality and Real-Time Rendering with DXR and Other APIs

Ray Tracing Gems: High-Quality and Real-Time Rendering with DXR and Other APIs

Book Description
This book is a must-have for anyone serious about rendering in real time. With the announcement of new ray tracing APIs and hardware to support them, developers can easily create real-time applications with ray tracing as a core component. As ray tracing on the GPU becomes faster, it will play a more central role in real-time rendering. Ray Tracing Gems provides key building blocks for developers of games, architectural applications, visualizations, and more. Experts in rendering share their knowledge by explaining everything from nitty-gritty techniques that will improve any ray tracer to mastery of the new capabilities of current and future hardware.

What you'll learn: 
  • The latest ray tracing techniques for developing real-time applications in multiple domains
  • Guidance, advice, and best practices for rendering applications with Microsoft DirectX Raytracing (DXR)
  • How to implement high-performance graphics for interactive visualizations, games, simulations, and more
Who this book is for:
  • Developers who are looking to leverage the latest APIs and GPU technology for real-time rendering and ray tracing 
  • Students looking to learn about best practices in these areas
  • Enthusiasts who want to understand and experiment with their new GPUs
