forward ray tracing - Illuminating Engineering Society
https://www.ies.org/definitions/forward-ray-tracing/
forward ray tracing. [9.6.4.1] A ray tracing method that casts rays from the light sources to receiving surfaces, and then recasts additional rays from these receiving surfaces to determine the interreflected light within a space or physical environment. « Back to Definitions Index.

Forward Raytracing In this case, the program simulates rays of light (or other spectra) that emanate from a light source, and determines where they end up when following a number of reflecion on scene surfaces. This method is normally used in the design of luminaire reflectors and other optical equipment. Backwards Raytracing

Forward Raytracing. Use this component to get a sense of how sunlight is reflected by a set of context geometries by tracing sun rays forwards through this geometry. Examples where this component might be useful include the evaluation of the diffusion of light by a light shelf, or testing to see whether a parabolic building geometry (like a ...

In these hybrid solutions, only certain levels of forward ray tracing is performed. The algorithm records the data, then goes on to perform backward ray tracing. The final coloring of the scene takes both the backward ray tracing and the forward ray tracing calculations into account. Three major hybrid solutions have been proposed over the years.

Ray Tracing: Backward v/s Forward Ray Tracing
https://ray-tracing-conept.blogspot.com/2015/01/backward-vs-forward-ray-tracing.html
In forward ray tracing ray start from light then hit the surface and enter our eye as shown in the picture above (see the arrow sign). According to physics the color that we see of the object is one that object reflect. Object absorb some colors and reflect another color. In Backward Ray Tracing, what we implement in our ray tracer, is opposite ...

Forward tracing means to them shooting rays from the camera because it is the most common path tracing technique used in CG. To avoid confusion you can also use the terms light and eye tracing which are more explicit These terms are more often used in the context of bi-directional path tracing (see the Light Transport section).

It can be used in all types of rendering (forward, deferred, raytracing). openFrameworks: ofxPBR addon (my fork from yasuhirohoshino) allows to render objects with metallic (reflection) and roughness properties, and apply shadows, see image below:

• Starting at the light (a.k.a. forward ray tracing, photon tracing) • Starting at the eye (a.k.a. backward ray tracing) 6 Whitted ray-tracing algorithm 1. For each pixel, trace a primary ray to the first visible surface 2. For each intersection trace secondary rays: – Shadow rays in directions Li to light sources – Reflected ray in ...
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
Ray tracing (graphics) Not to be confused with Ray tracing (physics). This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a ...
