Forward ray tracing is also known as light ray tracing and photon tracing. Backward Ray Tracing To make ray tracing more efficient, the method of backward ray tracing is introduced. In backward ray tracing, an eye ray is created at the eye; it …

Backward v/s Forward Ray Tracing - Blogger

In backward ray tracing we shoot a ray from our eye (camera) toward object and then render the color of object by shooting the ray from the intersection point on the object toward light. The problem with the implementation of forward ray tracing is that the scene contain many objects and photon ray (light ray) shot from the source hit many surfaces …

Image Formation (Forward) Ray Tracing (Backward) Ray Tracing Shadow Ray When the ray hits an object, a secondary ray, ("shadow" ray), is shot towards the light sources Determine if that point on the object is in a shadow.

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
Various Types of Ray Tracing Algorithm - EDUCBA

To a certain level, forward tracing is applied and algorithms are used to record this data and then backward tracing is applied to this data. The final coloring of the complete picture is calculated based on both forward and backward trace records. Ray tracing algorithm became quite popular due to its feature of realistic stimulation of lighting.
Checking for Forward and Backward Traceability in a …

Checking forward traceability: taking a batch of materials/components and tracing them through the process, including work in process, all the way to the finished products that were made with those materials/components. Checking backward traceability – this is taking a finished product batch and tracing it, starting from the customer, back ...

Instead of tracing rays from the light source to the receptor (such as our eye), we trace rays backward from the receptor to the objects. Because this direction is the reverse of what happens in nature, it is fittingly called backward ray-tracing or eye tracing because we shoot rays from the eye position?(figure 2). This method provides a convenient solution to the flaw of forwardi ray …
Trace Forward and Trace Back | Traceability Solutions

For traceability, parts and products are identified individually or by lots and information is accumulated in each process. Tracing forward means using accumulated information to track the movement of products and tracing back means tracking records backward in the timeline. However, it makes little sense to just identify parts and products or accumulate information.
What is Forward & Backward Traceability? - IFSQN
https://www.ifsqn.com/forum/index.php/topic/20202-what-is-forward-backward-traceability/
The exact requirements for "Traceability" might vary slightly depending upon the auditing body. Typically, it is essential that you (the manufacturer) be able to trace any product (raw/intermediate/finished), or ingredient, or packaging material, etc. at least one step backwards (supplier) and one step forward (customer), accounting for any product/material still …
