WebJul 20, 1999 · Ray Tracing Introduction. Ray Tracing is a global illumination based rendering method. It traces rays of light from the eye back through the image plane into the scene. Then the rays are tested against all objects in the scene to determine if they intersect any objects. If the ray misses all objects, then that pixel is shaded the background color. Weblike to investigate commonly used data structures that support efficient ray tracing. This survey is organized as follows. Part I provides background information and history of ray tracing. In section 2, we define the problem and introduce the terminology used in this survey. Each data structure is also briefly mentioned there. buck saws for cutting firewood https://stagingunlimited.com
