NVIDIA during the GDC 2019 Game Developers Conference devoted the lion's share of the news to real-time ray tracing technology. This is not surprising: for now, you can see such technologies live in games only on its Turing family graphics accelerators (support for old cards based on Pascal chips is soon promised), although they may also become the property of AMD Radeon video cards. One of the announcements was the upcoming support for RTX in the Unity game engine.
To better showcase the promise of real-time ray tracing technology, Unity partnered with NVIDIA and the BMW Group to create a demo that tries to recreate the exterior and interior of the 8 BMW 2019 Series Coupe in great detail.
Previously, it was considered impossible to achieve efficient real-time ray tracing for photorealistic image quality and lighting in any task where visual fidelity is very important, such as design, engineering or marketing, where pre-rendering mode was always used.
During the presentation of this demo, NVIDIA's CEO even challenged the public to differentiate between a real shot of a BMW car and a virtual car rendered on screen by Unity's real-time ray tracing hybrid rendering engine.
Unfortunately, don't expect real-time ray-traced Unity games to appear too soon - full support is promised only in 2020. However, a preview version that can already be used in real projects will appear in the fall of 2019, and an early experimental build will be released on April 4 on GitHub. Recall that Unreal Engine will receive final support for DirectX Raytracing in version 4.22, which will be released one of these days.
