Ray tracing migration uses a model of the sub-surface to carry out the ray tracing exercise. The results are iteratively updated to reduce the discrepancies between the observed and calculated reflection times. This ray tracing method is the only migration technique to give satisfactory results in complex areas.

Ray tracing is made easier in the case of rays approaching the optical axis. In that case, the argument α of sine and tangent functions is α ≪ 1 rad; expanding in power series and retaining only the first significant term, it is written as [19] sin α ≈ tan α ≈ α
An Overview of the Ray-Tracing Rendering Technique

Ray-tracing is a technique for computing the visibility between points. Light transport algorithms are designed to simulate the way light propagates through space (while interacting with objects). They are used (in short) to compute the color of a point in the scene. Do not mix ray-tracing with light transport algorithms.

Overview of Ray Tracing References In ray tracing, a ray of light is traced in a backwards direction. That is, we start from the eye or camera and trace the ray through a pixel in the image plane into the scene and determine what it hits. The pixel is then set to the color values returned by the ray. Sometimes the ray misses all of the objects:

Ray tracing is a rendering technique that can realistically simulate the lighting of a scene and its objects by rendering physically accurate reflections, refractions, shadows, and indirect lighting.

Algorithm overview The ray-tracing algorithm builds an image by extending rays into a scene and bouncing them off surfaces and towards sources of light to approximate the color value of pixels. Illustration of the ray-tracing algorithm for one pixel (up to the first bounce)

Ray tracing is an important simulation technique based on its relative accuracy (for many situations) combined with its general computational efficiency, compared to more rigorous methods of propagating electromagnetic waves. Ray tracing can be combined with other computational algorithms to more accurately simulate physical phenomenon.
Ray tracing propagation model - MATLAB

Create a ray tracing model. Use the image method and calculate paths with up to one reflection. Then, display the propagation paths. pm = propagationModel ( "raytracing", "Method", "image", ... "MaxNumReflections" ,1); raytrace (tx,rx,pm) For this ray tracing model, there is one propagation path from the transmitter to the receiver.

Ray tracing (physics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(physics)
In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating analysis.
