NVIDIA Launches VRWorks Audio and 360 Video SDK at GTC

Developers can download the VRWorks SDK’s today.

Today sees the start of NVIDIA’s GPU Technology Conference (GTC) at the San Jose Convention Center, California. Virtual reality (VR) will play a big part in the proceedings, with multiple sessions taking place as well as announcements. The first two are the VRWorks Audio software development kit (SDK) and VRWorks 360 Video SDK, both releasing publicly for the first time.

The VRWorks Audio SDK will feature real-time OptiX ray-tracing of audio in virtual environments and a plugin for VRWorks Audio in Unreal Engine 4. While normal VR audio provides an accurate 3D position of the audio source within a virtual environment, NVIDIA VRWorks Audio will help make that even more immersive by modeling sound propagation phenomena such as reflection, refraction and diffraction.

Its release consists of a set of C-APIs for integration into any engine or application that is available now on GitHub. And GTC attendees get a live demonstration of VRWorks Audio technology at the VR Village to experience.


At the conference NVIDIA will be demoing for the first time the release of the VRWorks 360 Video SDK that enables stereo stitching in real-time. Utilising two Quadro P6000 GPUs, the company will showcase how it’s able to stitch eight 4k cameras in stereo and in real-time using Z CAM’s V1 PRO rig.

“The fact that NVIDIA manages to stitch 4K 360 stereoscopic video in real time, making livestreaming possible, changes the production pipeline and enables entirely new use cases in VR,” said Kinson Loo, CEO of Z CAM.

From today, the first public beta of the VRWorks 360 Video SDK is available to all developers from developer.nvidia.com/vr. Today’s launch is for the VRWorks 360 Video SDK in mono, while VRWorks 360 Video SDK for stereo will be released soon.

VRFocus will continue its coverage of GTC 2017, reporting back with all of the latest updates and announcements.
