Ray casting is the process in a ray tracing algorithm that shoots one or more rays from the camera (eye position) through each pixel in an image plane, and then tests to see if the rays intersect any primitives (triangles) in the scene.

The ray-tracing algorithm takes an image made of pixels. For each pixel in the image, it shoots a primary ray into the scene. The direction of that primary ray is obtained by tracing a line from the eye to the center of that pixel.

Ray Tracing algorithm Real-world Mechanisms. How do we see an object with our eyes? As we all know, it's because of the light. Imagine you're... Simulation. So, this is the real-world mechanism for seeing things, but is it easy to implement? The answer is no. Sun... Backward Tracing. We shoot rays ...

In order to produce Ray Traced images, we follow the basic ray tracing algorithm, as follows: for (each pixel (sample) on the viewing area) { for (each primitive in the world model) { if (ray-pixel intersection) { select the frontmost intersection; recursively trace the relection and refraction rays; calculate color; } } }

c,z. c) and radius R can be represented as: (x-x. c) + (y-y. c) + (z-z. c) - R = 0 For a point pon the sphere, we can write the above in vector form: (p-c). (p-c) - R = 0 (note ‘.’ is a dot product) We can plug the point on the ray p(t) = e+ t d. (e+td-c). (e+td-c) - R = 0 and yield (d.d) t + 2d.

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
