Radiosity does not account for specular reflections (i.e. it only handles diffuse reflections). Whitted's ray-tracing only considers glossy or diffuse reflection, possibly mirror-reflected. And finally, Kajiya's path-tracing is the most general one [2], handling any number of diffuse, glossy and specular reflections.

Ray tracing is an image-space algorithm, while radiosity is computed in object-space Because the solution is limited by the view, ray tracing is often said to provide a view- dependent solution , although this is somewhat misleading in that it implies that the radiance itself is dependent on the view, which is not the case. The term

Technically, path tracing (which is a kind of raytracing) implements the complete lighting equation. But they probably meant indirect lighting, iow. global illumination. Share. Improve this answer. Follow this answer to receive notifications. answered Jun 6, 2012 at 10:59. FeepingCreature.
raytracing vs. radiosity by podlovics

I love the fact that the ray-tracing rendered image has its unique distinction. I prefer the ray-tracing image and method. But the radiosity image is excellent too. Thanks alot for this great comparative image. ) podlovics 12:20AM | Thu, 23 March 2006. The machine is a duocore amd 3800 x2, with 2GB RAM.
Radiosity - Ray Tracing
https://www.cg.tuwien.ac.at/research/rendering/rays-radio/
The two most popular methods for calculating realistic images are radiosity and ray tracing. The difference in the simulation is the starting point: Ray tracing follows all rays from the eye of the viewer back to the light sources. Radiosity simulates the diffuse propagation of light starting at the light sources. Ray Tracing
Comparison of radiosity and ray-tracing methods for ...

In this study, we compare results of the radiosity method and ray-tracing technique applied to coupled rooms. 2. The ray-tracing technique In a simple way, each source is broken up into a large number of rays. All rays has the same power for omni- directional source. The ray power decrease with the source- receiver distance.

The TLDR; for the radiosity map is as so: traces 300+ rays on a sphere above diffuse voxels in compute against emissives/other diffuse voxels. Rays reflect against (mostly-)glossy voxels and reflect/refract through di-electric voxels. If the diffuse voxel hit has radiance stored in the hit facet, it is returned back as irradiance.

In fact, because ray tracing is so computationally intensive, it’s often used for rendering those areas or objects in a scene that benefit the most in visual quality and realism from the technique, while the rest of the scene is rendered using rasterization. Rasterization can still deliver excellent graphics quality. What’s Next for Ray Tracing?
