Reverse Raytracing – what is it about? Solution “The concept of “Reverse Raytracing” is designed to make raytracing more efficient, that is, to allow TracePro to trace rays of interest and not consume resources tracing rays that do not contribute to the solution of the engineering/design problem.
Reverse ray tracing for transformation optics - PubMed
https://pubmed.ncbi.nlm.nih.gov/26191770/
In this study, we present the use of 3D reverse ray tracing in transformation optics. The reverse ray tracing is derived from Fermat's principle based on a sweeping method instead of finding the full solution to ordinary differential equations. The sweeping method is employed to obtain the eikonal function.

Reverse ray-tracing was used to calculate radiative exchange by emission. • The method ensures radiative flux values are bounded within a “reasonable” range. • Ray-tracing calculations were accelerated by using GPU computing. • Simulations were performed with more than 500 fully resolved trees. Abstract

Backward ray tracing is also known as eye ray tracing. The downfall of backward ray tracing is that it assumes only the light rays that come through the viewplane and on into the eye contribute to the final image of the scene. In certain cases, this assumption is flawed.

This reverse tracing process of eye/camera to light source is chosen because it is far more efficient than tracing all light rays emitted from light sources in multiple directions. Another way to think of ray tracing is to look around you, right now. The objects you’re seeing are illuminated by beams of light.

Ray tracing results can be used for many diagnostic and analysis purposes. For example, the size of the image quality for a microscope objective can be estimated by tracing rays through it in reverse, to see how well the light focuses. Cutaway view of a microscope objective, focusing rays at points under a cover glass.
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
The idea behind ray casting, the predecessor to recursive ray tracing, is to trace rays from the eye, one per pixel, and find the closest object blocking the path of that ray. Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.
