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 ...

1. Forward Ray Tracing Algorithm. In this technique, the program triggers rays of light that follow from source to the object. Forward ray tracing is capable of determining the color of each object however this technique is inefficient. This is due to the fact that many rays from a light source never come through view plane and into the eye.

In computer graphics the concept of shooting rays either from the light or from the eye is called path tracing. The term ray-tracing can also be used but the concept of path tracing suggests that this method of making computer-generated images relies on following the path from the light to the camera (or vice versa).
What Is Ray Tracing and How Does It Work?
https://www.makeuseof.com/what-is-ray-tracing/
Ray tracing performs a process called “denoising,” where its algorithm, beginning from the camera—your point of view—traces and pinpoints the most important shades of light and shadows. Using machine learning, it ‘fills in the gaps’ to form a photorealistic image. So, the brighter the scene in a video game, the higher the graphics ...

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.

Whitted-style Ray Tracing • Turner Whitted introduced ray tracing to graphics in 1980 • Combines eye ray tracing + rays to light and recursive tracing • Algorithm: 1. For each pixel, trace primary ray in direction V to the first visible surface. 2. For each intersection trace secondary rays: • Shadow in direction L to light sources
