Скачать или смотреть How does Ray Tracing work? Lets understand by implementing it from scratch!

Ray Tracing is one of the most popular algorithms right now for rendering realistic 3D graphics on screen. Its usage has received further boost after recent advancement in GPUs. But how does Ray tracing work? In this Video we will try to understand its internals by rendering a very simple scene using Ray tracing from scratch.
Since covering Ray tracing completely in a single video is next to impossible, we will try to understand the basics in this video. In later videos we will try to understand things like types of surfaces/materials, light and shading etc.
