Graphics and rendering in an XRAn umbrella term encompassing Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) applications. Devices supporting these forms of interactive applications can be referred to as XR devices. More info
See in Glossary app follow the same principles as they do in any Unity application, with some differences arising from the need for stereo rendering and increased efficiency.
XR apps generally require very high and consistent frame rates for user comfort. At the same time, rendering in stereo means that every visible object must be drawn twice from different perspectives. Techniques like single-pass rendering can improve rendering efficiency by reducing the duplication of effort, but also require changes to shaderA program that runs on the GPU. More info
