Global Illumination vs Ray Tracing vs Path Tracing? : PS5

Not really the same. Global lumination does an approximation, and while good it is not as good as ray tracing. Ofcourse the benefit is that it is not nearly as much demanding as ray tracing. Global lumination can be combined with ray tracing as well. Path tracing is a subset of ray tracing.

global illumination model is more comprehensive, more physically correct, and it produces more realistic images. Ray tracing is an essential subject when it comes to computer graphics. It combines issues of efficiency and realism, thus finding a favorable balance of the time and effort involved to make realistic three dimensional images.
Is ray tracing a global illumination? - Quora
https://www.quora.com/Is-ray-tracing-a-global-illumination
Global Illumination is feature of Ray Tracing that allows synthetic light rays to reflect off surfaces to light up other areas. It requires a massive amount of processing power as there are far more light ray interactions needing to be calculated.

So even at current state, raytraced global illumination is not something that one would want to put in a game, and is suited better for rendering cinematics. Raytracing is an amazing technology, and I can only wait till the day in which raytracing games will be able to run at 60FPS at ultra on a xx60 card! Source:
RTX Vs Global Illumination I'M NOT CONVINCED! - Linus …
https://linustechtips.com/topic/1280504-rtx-vs-global-illumination-im-not-convinced/
Ray-traced lighting against a real time global illumination solution is a bit more limited to its main benefit being accuracy and an easier way to make it more dynamic, per se. But there's tons of great examples of both baked and real-time GI that ray-traced lighting is a bit harder to justify as of this moment.
RTX Global Illumination (RTXGI) | NVIDIA Developer
https://developer.nvidia.com/rtx/ray-tracing/rtxgi
RTX Global Illumination (RTXGI) Leveraging the power of ray tracing, the RTX Global Illumination SDK provides scalable solutions to compute multi-bounce indirect lighting without bake times, light leaks, or expensive per-frame costs. RTXGI is supported on any DXR-enabled GPU, and is an ideal starting point to bring the benefits of ray tracing to your existing tools, knowledge, and …
Chapter 3 Ray Tracing 3.1 Local vs. Global Illumination
http://www.forejune.co/stereo/rt-samples3.pdf
Ray tracing is one of the global illumination techniques; it eliminates the use of a depth buffer to determine hidden surfaces and allows for many special effects. In summary, ray tracing unifies in one framework hidden surface removal, shadow com- putation, reflection of light, refraction of light, and global specular interaction.
Unreal Engine 5 Lumen vs Ray Tracing: Which Is Better?
https://gamersdiscussionhub.com/unreal-engine-5-lumen-vs-ray-tracing/
Lumen vs Ray Tracing Hardware Requirement. Lumen has an advantage in terms of hardware requirements because it does not require the same level of light calculation as ray tracing. This means that lumen can render realistic light but does …
A Look at Screen Space Ray Traced Global Illumination
https://www.hardwaretimes.com/a-look-at-screen-space-ray-traced-global-illumination-lighting-in-days-gone-performance-and-quality-comparisons/
Although the game doesn’t feature full-fledged hardware-accelerated ray-tracing like Metro Exodus or Control, it does come with what’s called Screen Space Ray Traced Global Illumination. This is basically a shader-based form of ray-tracing that is a huge improvement over Screen Space Ambient Occlusion.
