Rtx 2048 quake ii12/2/2023 As such, path tracing reduces the artist and engineering time (and therefore cost) required to create high-quality content.Īnd now, we have NVIDIA’s Turing RTX GPUs–the first GPUs with ray tracing hardware acceleration, ushering in the era of game ray/path tracing and hardware-accelerated offline path tracing. Quake 2 RTX’s path tracing pushes that number up to a few hundred lights. In contrast most current games only support shadows from a small number of dynamic light sources additional lights either must be static or cannot cast shadows. Path tracing also allows artists and content creators to light their CG scenes using the same expectations of how lighting works in the real world, supporting scenes with thousands to millions of individual light sources. ![]() This flexibility means that path tracing scales gracefully to highly complex content. Furthermore, path tracing supports a wide variety of types of reflection from surfaces-from shiny glossy surfaces like metal, to diffuse surfaces like matte paint, to specular surfaces like water and glass. All of these have very different visual appearances, but are all handled in the same way when path tracing is used. One example of its generality is that path tracing supports a wide variety of types of light sources-from the sun and skylight, to spotlights, to volumetric lights such as fire, to broad diffuse area light sources. In contrast, other earlier lighting techniques are specialized to individual effects (e.g., “shadows cast by smoke”.) Its advantage over other approaches: it’s a single unified algorithm that accurately simulates the behavior of light in almost all circumstances. Path tracing is used ubiquitously for computer-generated movies and visual effects, and it delivers the photorealism that viewers have come to expect. This article describes inventions recently discovered by a team of NVIDIA researchers that aim to stretch the capabilities of real-time path tracing to highly complex scenes with thousands of dynamic light sources Quake 2 RTX shows off path tracing’s benefits, with complex lighting from hundreds of lights bringing breath-taking beauty to the twenty-one-year-old Quake 2 classic game. ![]() Path tracing is an advanced rendering technique that uses ray tracing to simulate the physics of light in a scene. ![]() The recent unveiling of Quake 2 RTX was a watershed moment for real-time computer graphics: it is the first fully path-traced game.
