A technique for determining, by tracing imaginary rays of light from the viewer’s eye to the objects in a scene, the parts of the scene that should be displayed in the resulting display image.  6, record 1, English, - ray%20tracing

Ray-tracing technique relies on an extremely time-consuming algorithm to compute the reflection and refraction of light from the surfaces of imaginary objects. Basically the computer program traces individual light rays, starting at the viewpoint and passing backward through each pixel in the image plane until the ray hits a surface. The reflected ray is then continued to see if it could have come from a light source, either directly or after reflection from another object. For a transparent surface a second, refracted ray must also be traced.  7, record 1, English, - ray%20tracing

ionospheric propagation mode. A single ray path between the transmitter and receiver. An ionospheric propagation path may comprise several different individual paths, all of which can propagate the signal from the transmitter to the receiver. The mode is labeled in terms of the number of reflections it experiences for each of the layers from which it is reflected. The simplest ionospheric mode is a single hop path having one reflection on the ionosphere... More complex modes can have several reflections from a layer... and may also have reflections from more than one layer...  3, record 2, English, - ionospheric%20propagation%20mode

The most computationally complex and most realistic algorithms for dealing with both reflection and refraction are called ray-tracing algorithms. In essence they trace individual light rays to determine which of them end up at the viewpoint and how they got there. In order to avoid having to deal with an infinity of lines emanating from a point source, the process works backward, starting at each pixel. Each ray starting at the viewpoint and passing through a pixel is projected backward until it hits a surface. The backward tracing of the reflected ray then continues to determine whether it could have come from a light source or from reflection from another object.  1, record 5, English, - ray%2Dtracing%20algorithm
