Real-Time RayTracing At GDC 2019
<div><p>At GDC 2018, <a href="https://www.gamefromscratch.com/post/2018/03/19/Microsoft-Announce-DirectX-Raytracing.aspx">Microsoft unveiled DXR</a>, or Direct X 12 Raytracing, an SDK enabling real-time raytracing, followed closely by NVIDIA announcing hardware support. This year at GDC 2019, those technologies have come of age, with major raytracing support coming from 3 major game engine manufacturers. Additionally NVIDIA have announced some potentially game changing news as well. Let’s break down the announcements and demonstrations one by one.</p>
<p><a href="https://www.cryengine.com/news/crytek-releases-neon-noir-a-real-time-ray-tracing-demonstration-for-cryengine">CryTek</a></p>
<p>CryTek started the raytracing announcements off with their amazing real time demo <a href="https://www.youtube.com/watch?v=1nqhkDm2_Tw">Neon Noir</a>. Even more impressive, it was done using an AMD card without real-time raytracing support! Unfortunately, the demo was never released to the public.</p>
<p><a href="https://unity.com/ray-tracing">Unity</a></p>
<p>Unity showed an impressive demo <a href="https://www.youtube.com/watch?v=AG7DDXwYpD0">Reality vs Illusion</a> which intercuts real world footage and real time raytraced BWM footage that is nearly impossible to discern the difference. Unity’s technology is sadly several months from being available in a future HDRP release.</p>
<p><a href="https://forums.unrealengine.com/unreal-engine/announcements-and-releases/1583659-unreal-engine-4-22-preview">Unreal Engine</a></p>
<p>Unreal is the closest with their real time raytracing implementation, in fact it’s available now in Unreal Engine 4.22. They also had a presentation in the form of the short movie <a href="https://www.youtube.com/watch?v=Qjt_MqEOcGM">Troll</a>.</p>
<p><a href="https://www.nvidia.com/en-us/geforce/news/geforce-gtx-ray-tracing-coming-soon/">NVIDIA</a></p>
<p>NVIDIA also had a real time raytracing demonstration in the form of <a href="https://www.youtube.com/watch?v=b2WOjo0C-xE">Project Sol, Part 3</a>. Their announcement may have been the most significant however, as they announced that DXR driver support will be shipping in April to older generation NVIDIA GPUs, such as the 1060/1070 and 1080 cards.</p>
