Ray tracing is very common technique for generating photo-realistic digital imagery, which is exactly what we’ll be doing in this series. Aside from learning all about ray tracing and the math to goes into it, as well as how to implement it, we’ll also be focusing on performance and optimization in C to make our renderer as efficient as possible. We’ll eventually switch to using the GPU instead of the CPU (using Vulkan) to run our ray tracing algorithms, as this will be much faster that using the CPU. This will also be a great introduction to leveraging the power of the GPU in the software you write. All of the code episode-by-episode will be released, and if you need help check out the #raytracing-series channel on my Discord server. I’m really looking forward to this series and I hope you are too! ❤️ CHAPTERS 0:00 - Lighting and shading in rendering 6:21 - Using floats for colors 12:07 - Why use floats instead of ints for colors? 12:52 - Finding our sphere hit coordinates 17:08 - Closest intersection point 19:40 - Using color to visualize numbers 21:02 - How lighting and shading works 22:45 - Calculating lighting using normal vectors 25:34 - Visualizing normals better 27:00 - Using math to calculate lighting and shade our sphere This video is sponsored by Brilliant. #RayTracing
