WebIn this problem, we go through the implementation of a cylinder ray tracing primitive, in much the form that it might be implemented in your ray tracing project. An in nite cylinder is de ned by a point p, a direction u (with YuY=1), and a distance r. The cylinder’s axis is the line with point p and direction u. WebWhere n is the index of refraction, c is the speed of light in a vacuum, and v is the phase velocity of the light in the material. A vacuum, while not strictly a material, has an index of 1. Water has an index of 1.3333. Glasses and plastics typically used for light guides have an index of about 1.45 to 1.6 for visible light.
