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
