This Star Wars scene showcases Epic Games’ implementation of Nvidia’s new RTX feature. Ray tracing is a rendering process of mapping light rays through an image to create realistic shading, reflections and depth-of-field. It requires incredibly powerful hardware to do quickly and we are only now seeing real-time implementations thanks to Nvidia’s Volta GPUs. Epic will use the DirectX Raytracing API (DXR) to make this feature available to Unreal developers later this year.
