PDF-Crepuscular rays

are formed when beams of sunlight shine through breaks in cloud cover The beams become visible as the sunlight reflects off of particles in the atmosphere and are enhanced by shadows cast between. W e reduce the number of ray marching samples for computing the inscattered light by placing them along epipolar lines a nd depth discontinuities center Our sampling strategy i s motivated by the observation that scattering varies mostly smoothly al Suter Department of Biology Vassar College 124 Raymond Avenue Poughkeepsie NY 12603 USA Email sutervassaredu Kari Benson School of Sciences Lynchburg College 1501 Lakeside Dr Lynchburg VA 24501 USA Abstract Animals are commonly categorized as diur - .

Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods. . used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye. X-rays was discover in 1895.. X-ray are shone through the body.. Each kid of tissue lets x-rays through differently.. X-rays are very good at showing up bones.so if you break a bone it will probably be x-rayed.. point the brighter the point. The more lights you turn on the brighter the reflected light from objects in the room. See rays at right. Intensity proportional to |E|. 2. Light. source 2. Light. source 1. Accidental discovery.
