•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) (now you know how to get s and e)

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 most serious disadvantage is the heavy computational requirement of the ray tracing algorithm. Advanced lighting e ects such as caustics are di cult to render usin ray tracing. 2 Algorithm The general algorithm of ray tracing is performed by tracing a path from an imaginary eye through each

Ray tracing was brought to a broad knowledge by Whitted [Wh80]. In its simplest form, for eac h pixel of the image a ray is traced from the viewpoint into the 3d scene to calculate its first in...

Basic algorithm is simple but VERY expensive. Optimized ray-tracing is critical Reduce number of rays traced Reduce number of ray-object intersection calculations Methods Bounding Boxes Object Hierarchies Spatial Subdivision (Octrees/BSP) Tree Pruning (Randomized) Bounding Volumes Bound each scene object by a simple volume (e.g. sphere).

Full Ray-Tracing • For each pixel – Compute ray direction – Find closest surface – For each light • Shoot shadow ray • If not shadowed, add direct illumination – Shoot ray in reflection direction – Shoot ray in refraction direction Dielectric if (pis on a dielectric) then r= reflect (d, n) if (d.n< 0) then refract (d, n, n, t) c = -d.n
Ray Tracing Tutorial - GitHub Pages
https://sebastiandang.github.io/docs/cse168/RayTracing.pdf
Ray tracing is one of the numerous techniques that exist to render images with computers. 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.
