In ray-tracing simulations one is faced with a complexity at points of intersection between rays and objects. How to handle the reflection, should it be specular or scattered. ... (reflection coefficient of 0.5 is assumed) or scattered. The ray then again travels for another 100 m without coming in contact with an object.

Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images. ... To test for this the ray tracer must compute and keep the product of the global and reflection coefficients as the rays are traced. Example: let Kr = 0.5 for a set of surfaces ...

Show activity on this post. Snell's law of refraction at the interface between 2 isotropic media is given by the equation: (1) n 1 sin θ 1 = n 2 sin θ 2. where θ 1 is the angle of incidence and θ 2 the angle of refraction. n 1 is the refractive index of the optical medium in front of the interface and n 2 is the refractive index of the ...
Reflection coefficient - Wikipedia
https://en.wikipedia.org/wiki/Reflection_coefficient
In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.For example, it is used in optics to calculate the amount of light that is reflected from …
