http://www.tweaktown.com/news/51052/nvidia-launches-gameworks-sdk-3-1-three-new-technologies/index.htmlGDC 2016 - NVIDIA has just announced its new GameWorks SDK 3.1, with three new technologies included in the release. This includes new techniques for shadows and lighting, as well as two new physical simulation algorithms, released in beta form.
As for the three new technologies with GameWorks SDK 3.1, this is what we can expect:
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 world-space using all scene geometry, as opposed to screen space techniques that can only shadow from geometry visible to the camera. VXAO debuted in the hit video game Rise of the Tomb Raider.
