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 Section . 31-7.

Effective; producing the desired outcome. The Discovery of Antimatter!. In 1932 Carl Anderson studied cosmic rays using a “cloud . chamber”. . Charged particles produced in cosmic rays would enter the chamber and leave “tracks”. The tracks would bend in circles because the chamber was placed in a strong magnetic field. 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.. 3D Projections. . -. Perspective and Parallel Projections. Parallel Projections: . . -.
