We'll call these flows “light rays.” wLight rays travel in straight lines in free space. wLight rays do not interfere with each other as they cross. wLight rays obey the laws of reflection and refraction. wLight rays travel from the light sources to the eye, but the physics is invariant under path reversal (reciprocity). 4 Eye vs. light ray tracing

The idea behind ray tracing is that physically correct images are composed by light and that light will usually come from a light source and bounce around as light rays (following a broken line path) in a scene before hitting our eyes or a camera.

We know the ray passes through O, and we know its direction (from O to V ), so we can express any point P in the ray as P = O + t ( V − O) where t is any real number. By plugging every value of t from − ∞ to + ∞ into this equation, we get every point P along the ray. Let’s call ( V − O), the direction of the ray, D →. The equation becomes

Ray tracing is a more sophisticated algorithm in global rendering involving diffraction and reflection, thus generating images looking even more realistic; alas, it emulates the physics but is computationally more expensive. Computation: Each ray is traced separately, so that every point (usually a pixel) on the display is traced by one ray.

Ray tracing algorithm generates an image by tracing the path of light through pixels in an image plane. It is capable of producing a very high degree of visual realism, but at a greater computational cost. Features: Model-View-Controller pattern Object-oriented programming Vector and matrix operations Texture loading using FreeImage

•We can represent the ray as a 3D parametric line p(t) = e+ t (s-e) (now you know how to get s and e) •Typically weoffset the ray by half of the pixel width and height, i.e, cast the ray from the pixel center e s s-e incrementing (i,j) (0,0) Put it all together •We can represent the ray as a 3D parametric line p(t) = e+ t (s-e)

2 Ray Tracing in the real world Light is emitted from light source Bounces off of the environment Assumptions Light travels in straight rays Path of light changes based on object interaction. Can simulate using basic geometry. Some light will reach and be focused by camera onto film plane. Lots of light will not! In image synthesis, we are only interested in the
