We'll give an overview of AR and VR (extended reality, or XR) graphics technologies from NVIDIA. From low-level APIs used to access special XR hardware features, such as variable rate shading or utilizing multiple GPUs, to complex libraries and technology stacks like XR streaming from the cloud. This talk is intended to give a broad overview of our latest tools and SDKs with pointers to more in-depth information. We'll focus primarily on new SDKs, as well as up-and-coming technologies in development. This will include SDKs for deep learning-based up-sampling and real-time streaming of global illumination data.
