CS 6965 Fall 2011 Euclidean geometry • Euclidean geometry defines 5 postulates: • A straight line segment can be drawn joining any two points. • Any straight line segment can be extended indefinitely in a straight line. • Given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as center. • All right angles are congruent.

The ray tracing technique attempts to model the physical properties oflight and can correctly handle such visual artifacts as shadows,reflection, and refraction. Ray tracing reverses the traditional rendering process. Instead ofprojecting each vertex of the geometric model onto the picture planeand then scan converting to determine the appropriate pixel values,ray tracing …
