WebAug 21, 2016 · The reflective component is determined by further ray tracing. The other component is calculated via the equation from the Phong reflection model. Our ray tracer currently adds both components as in (1 - reflectivity) * color + reflectivity * trace (reflected_ray, depth + 1) where color is determined by the Phong equation.

WebThe Blinn–Phong reflection model (also called the modified Phong reflection model) is a modification to the Phong reflection model developed by Jim Blinn. [1] Blinn–Phong is the default shading model used in OpenGL [2] and Direct3D 's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes ... WebJan 13, 1998 · Reflections use a Phong BRDF [42], where the Phong exponent is determined from the material scattering coefficient.
