NVIDIA RTX Real-Time Ray Tracing Technology Explained!

NVIDIA RTX Real-Time Ray Tracing Technology Explained!

NVIDIA just announced the NVIDIA RTX real-time ray tracing technology at GDC 2018. It promises to bring real-time, cinematic-quality rendering to content creators and game developers. Find out what NVIDIA RTX is all about, and what it means to all of us!

 

The Holy Grail For Photorealism

Ray tracing is the gold standard for creating realistic, lifelike lighting, reflections and shadows. It adds a level of realism far beyond what is possible using traditional rendering techniques.

Real-time ray tracing replaces a majority of the rendering techniques used today, with realistic optical calculations that replicate the way light behaves in the real world. But until today, it has been too computationally-demanding to be practical for real-time, interactive gaming.

 

NVIDIA RTX Real-Time Ray Tracing Technology

NVIDIA RTX is a real-time ray tracing technology that promises to deliver real-time ray tracing with high frame rates and low latency.

It runs exclusively (at the moment) on the NVIDIA Volta GPUs. Applications that run on the newly-announced Microsoft DirectX Raytracing (DXR) API will support NVIDIA RTX when used with an NVIDIA Volta graphics card.

 

GameWorks For Ray Tracing

NVIDIA also announced that the NVIDIA GameWorks SDK will include a ray tracing denoiser module. This suite of tools and resources will help developers increase realism and shorten product cycles for titles developed using the new Microsoft DXR API and NVIDIA RTX.

The upcoming GameWorks SDK — which will support Volta and future generation GPU architectures — enables ray-traced area shadows, ray-traced glossy reflections and ray-traced ambient occlusion.

With these capabilities, developers can create realistic, high-quality reflections that capture the scene around it and achieve physically accurate lighting and shadows.

 

Broad Industry Support

Industry leaders such as 4A Games, Epic, Remedy Entertainment and Unity featured NVIDIA RTX in their technology demonstrations at the Game Developers Conference 2018. They showed how real-time ray tracing can provide amazing, lifelike graphics in future games.

NVIDIA Releases Free Vault 1080 Mod For Fallout 4

You know a game is great if you’re inspired to create more content after you’ve finished playing. And that’s exactly what we’ve done for Bethesda’s acclaimed post-apocalyptic survival adventure, Fallout 4.

 

Vault 1080 Mod For Fallout 4

Vault 1080 is a free add-on level mod by NVIDIA’S LightSpeed Studios. It adds over an hour of gameplay in an expansive vault featuring key NVIDIA GameWorks technologies, such as volumetric lighting, god rays, HBAO+ and FleX-powered weapons debris.

The gameplay is set in the dark underground hallways of Vault 1080, the home of a mysterious congregation that embraced darkness and sickness to survive. You’ll search for the truth within the depths of the mysterious vault, and judge for yourself whether monsters deserve salvation.

NVIDIA GameWorks Used For Unsettling Effects

The story behind the story: a team of NVIDIA Fallout 4 fans who couldn’t resist the opportunity to participate after Bethesda released its Fallout 4 Creation Kit. Led by veteran game modder Dane Johnston, with modding credits for Battlefield 1942, Battlefield 2 and Homeworld our team of developers spent an afternoon brainstorming the mod’s storyline. They then poured in around seven man-months of work to create our mod.

The result is more than just a sprawling environment — which takes you to the ruins of an old church hidden in a foggy, murky marsh. It’s a tale of lost secrets and unknown horrors told with technology that perfectly complements Vault 1080’s unsettling tale.

NVIDIA used GameWorks technologies such as volumetric lighting to light the corridors and rooms to create a great deteriorating atmosphere for players. Shadows was enhanced by NVIDIA HBAO+. Weapons debris comes courtesy of NVIDIA FleX.

SEGA and Warner Games Now Available On GeForce NOW

Two more top game publishers will be streaming their titles on NVIDIA SHIELD with GeForce NOW, bringing the total number of PC games available to stream on our Android TV device to 100.

SEGA and Warner Bros Interactive Entertainment will add a combined nine hit titles to the GeForce NOW service in the coming weeks. NVIDIA announced the additions at the Game Developers Conference, in San Francisco. Square Enix added games to the service just last month.

GeForce NOW is the world’s most powerful game-streaming service. It features cloud access to GeForce GPUs and a click-to-play time of less than 30 seconds – 100x faster than waiting for traditional digital downloads. It’s
the fastest, easiest way to play great video games, and GeForce NOW is only available on NVIDIA SHIELD Android TV – the fastest, Android-based media-streaming device for the living room.

NVIDIA GameWorks SDK 3.1 Launched

March 15, 2016 — NVIDIA today announced worldwide availability of the NVIDIA GameWorks SDK (software development kit) 3.1, which introduces three groundbreaking graphics techniques for shadows and lighting as well as two new physical simulation algorithms released as betas.

“It’s our passion for gaming that drives us to tackle the technical problems presented by realtime rendering and simulation,” said Tony Tamasi, senior vice president of content and technology at NVIDIA. “Our GameWorks technologies push the boundaries of what’s possible in real time, enabling developers to ship their games with state of the art special effects and simulations.”

 

The New GameWorks Rendering Techniques

  • NVIDIA Volumetric Lighting — an advanced lighting technique that simulates how light behaves as it scatters through the air and atmosphere. NVIDIA Volumetric Lighting was first introduced in the hit video game Fallout 4.
  • NVIDIA Hybrid Frustum Traced Shadows (HFTS) — an algorithm for drawing high-fidelity shadows that transition smoothly from hard shadows near the occluding object, to proper soft shadows in regions farther away. HFTS debuted in the hit video game Tom Clancy’s The Division.
  • NVIDIA Voxel Accelerated Ambient Occlusion (VXAO) — NVIDIA’s highest quality algorithm for real-time ambient occlusion, VXAO is a shading technique that adds depth and realism to any scene. It surpasses older techniques by calculating shadows in worldspace using all scene geometry, as opposed to screen space techniques that can only NVIDIA Advances Real-Time Game Rendering, Simulation with NVIDIA GameWorks SDK 3.1

The Extensions To The NVIDIA PhysX Library

  • NVIDIA PhysX-GRB — a new implementation of NVIDIA’s popular PhysX rigid body
    dynamics SDK, which has been used in hundreds of games. This hybrid CPU/GPU physics
    pipeline improves performance by a factor of up to 6X for moderate to heavy simulation
    loads.
  • NVIDIA Flow — a computational fluid dynamics algorithm that simulates and renders
    combustible fluids such as fire and smoke. Unlike previous methods, Flow isn’t limited
    to simulation of the fluids inside a bounding box.

NVIDIA makes source code for select GameWorks libraries available to developers via GitHub. Source code for NVIDIA Volumetric Lighting and NVIDIA’s FaceWorks demo is available today. Source code for NVIDIA HairWorks, NVIDIA HBAO+ and NVIDIA WaveWorks will be available soon.
