Stochastic ray tracing or photon mapping can simulate light scattering. Phong and Gouraud shading are reflection models applied to at a surface. It is common for people starting out in ray tracing to use a Phong or Gouraud lighting model. You can use those lighting models with any rendering system (scan conversion for example). Share

Phong model (Specular Reflection) in Computer Graphics
https://www.geeksforgeeks.org/phong-model-specular-reflection-in-computer-graphics/
An empirical model for calculating the specular reflection range, invented by the Phong Bui Tuong is also known as Phong specular reflection model. This model sets the intensity of specular reflection directly proportional to the cosns(∅). The range of …

Phong Illumination Model • 1.Calculate color for arbitrary point on surface • Compromise between realism and efficiency • Local computation (no visibility calculations) • Basic inputs are material properties and l, n, v: l= unit vector to light source n= surface normal v= unit vector to viewer r= reflection of lat p– (determined by land n)

That is, Phong calculates specular using the angle between the reflected eye vector and the light vector. In the diagram you posted, these vectors are shown and the angle is given as 15°. So, R·L = cos (15°) = 0.96 according to the table below the diagram. Share Improve this answer answered Mar 29, 2016 at 17:20 Nathan Reed 23.6k 2 61 99

Ray Tracing • For each pixel of the image do: • trace the ray into the scene • get the first hit object //visibility • evaluate its illumination • cast shadow rays //shadows • trace the reflected ray (if any) • trace the refracted ray (if any) • accumulate the results • also called the Whitted illumination model 3 © Bedrich Benes Ray Tracing

To follow the paths of light rays, ray tracing makes use of the characteristics of light: 1.Light rays travel in straight lines. 2.Light rays do not interfere with each other even if they cross over. 3.Light paths are reversible. If a light ray can travel from point Ato …
