Ray Tracing on the Cell Processor
https://www.sci.utah.edu/publications/benthin06/cell.pdf
One way of mapping ray tracing to the Cell is to have each SPE perform only one of these tasks, and to send its results to the SPE that performs the next task in the chain. For example, one SPE could generate primary rays which are then sent to one or more SPEs doing the traversal, which in turn send ray-triangle intersec- tion tasks to other SPEs.

Simple Ray Tracer is a platform independepent 3D rendering engine using a technique known as Ray Tracing. The programming language is c++ and the code is object oriented, very simple, and intuitive. It provides a great foundation to learn ray tracing. wxWidgets A cross-platform GUI library art-template High performance JavaScript templating engine

One particular example of such an architecture is the cell broadband engine architecture (CBEA), a multi-core processor that offers a raw compute power of up to 200 GFlops per 3.2 GHz chip. The cell bears a huge potential for compute-intensive applications like ray tracing, but also requires addressing the challenges caused by this processor's ...
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
Optical ray tracing describes a method for producing visual images constructed in 3D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques. It works by tracing a path from an imaginary eye through each pixel in a virtual screen, and calculating the color of the object visible through it.
Dynamic ray tracing for modeling optical cell manipulation
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3408928/
In this manuscript, we present a numerical method, dynamic ray tracing (DRT) and calculate the cell stress distribution due to light–cell interactions for arbitrary cell shape and simulate the resulting cell deformation in optical traps and stretchers. We do this by combining two numerical methods.

Ray tracing dielectrics •Like a simple mirror surface, use recursive ray tracing •But we need two rays –One reflects off the surface (same as mirror ray) –The other crosses the surface (computed using Snell’s law) •Doesn’t always exist (total internal reflection) •Splitting into two rays, recursively, creates a ray tree
Ray Tracing on the Cell Broadband Engine

For our project, the main core of our ray tracer is located on the PPU. This is what generates the geometry and viewpoint for the scene. The PPU app then prepares our ray trace engine to run on the six SPUs. The PPU app splits the workload between the SPUs evenly. It generates a “work unit” containing information such as

As a hardware-based ray tracing solution Imagination’s ray tracing IP is more power-efficient. Our 2016 Wizard dev board was built on a 28nm process and drew only 10 watts while generating a peak rate of 300MRay/sec and performance per watt would only be aided by today’s smaller manufacturing processes.
