VFX Voice MagazineVFX Voice Magazine: Critical in simulating the realistic physical properties of light as it moves through and interacts with virtual environments and objects is ray tracing, which can become cumbersome at render time, especially with complex imagery. A huge technical and creative effort has been made by the likes of NVIDIA, Unity Technologies, Chaos Group, Epic Games and The Future Group to be able to translate the pixels representing the paths of light within real-time.

I am currently writing this as my computer fans spin like a jet engine ready for take off. This is because it is rendering 3D animated scene using ray tracing. It is hugely taxing process so hearing about these kinds of advancements is really welcome. It makes sense to me that ray tracing is necessary to render 3D games in real time, but it is interesting to hear that High Definition Render Pipeline Real Time Ray Tracing (which they thankfully abbreviate as HDRP RTRT) is starting to come around and be more useful for people working in anything involving 3D rendering. It is crazy to think that a Pixar quality animation could be cranked out much faster due to these advancements. A lot of the test images that were used in the article were really amazing examples of the kinds of results that this technology yields. It looks very photorealistic even though it is computer generated.
