What is Ray Tracing? "Ray Tracer creates three-dimensional, photo-realistic images using a rendering technique called ray tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file.

the procedure can be outlined like this: 1.build a virtual world of lenses and mirrors, through which rays of light will pass. 2.create a ray with an origination point and angle, that is, a polar vector with a defined origin. 3.in the direction given by the angle, make a list of all objects the ray would intersect and the details of the …

A ray of light in air is approaches a triangular piece of crown glass at an angle of 0.00 degrees (as shown in the diagram at the right). Perform the necessary calculations in order to trace the path of the light ray as it enters and exits the crown glass. Refer to the table of indices of refraction if necessary. Solution to Problem C

Whitted-style Ray Tracing • Turner Whitted introduced ray tracing to graphics in 1980 • Combines eye ray tracing + rays to light and recursive tracing • Algorithm: 1. For each pixel, trace primary ray in direction V to the first visible surface. 2. For each intersection trace secondary rays: • Shadow in direction L to light sources
