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. Ray tracing generates computer graphics images by tracing the path of light from the view camera (which determines your view into the scene), through the 2D viewing plane (pixel

Ray tracing: Explained. As a graphic technology, ray tracing allows for the fluid simulation of lighting effects. An algorithm emits rays in the form of a 3D graphic, traces the rays’ paths and then calculates a realistic lighting model. Anyone that is familiar with computer games and graphics cards will inevitably be familiar with ray ...

Now that the distinction between ray-tracing and light transport algorithm was established, we can finally introduce one of the most classical examples of light transport algorithm based on ray-tracing. ... The technique was first detailed in 1980 by Turner Whitted in a Siggraph paper titled "An Improved Illumination Model for Shaded Display ...

One problem with discussing ray-tracing is that ray-tracing is an overloaded term. 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.

In ray tracing, we want to reproduce the effects of a global lighting model, with visual interaction between separate parts of the model, such as occluded light (shadows), reflections, and refractions. Shadows. We can cast an additional ray from the point of nearest intersection towards the light source.

$\begingroup$ "I know what a lightning model does, eg Phong, Flat, Gouraud." And yet, those are not lighting models. They're ways of interpolating the normal across a surface. There is such a thing as the Phong lighting model, but that's distinct from Phong shading.As far as I know both Ray Tracing and Global Illumination are just lighting models
Week 6: Lighting, Intro to Path tracing methods
https://www.cs.swarthmore.edu/~adanner/cs40/f20/notes/week06.html
The primary challenge in all path tracing techniques is how to model the scene and compute ray object intersections. In the ray marching method, an object surface is represented by a signed distance field, or SDF. The SDF is a function that when given a point returns a scalar distance indicating how close that point is to a surface.
