DisplayXR

DisplayXR is a Gaussian Splatting viewer built for glasses free 3D displays, rendering with Vulkan behind an OpenXR runtime. The reference application is published under Apache 2.0 as displayxr-demo-gaussiansplat, a C++ project, and each version ships as four builds covering Windows, macOS, Linux and Android.

The viewer loads .sog bundles directly, including the optional camera block that a bundle can carry. That camera data is what the newer of its two rigs depends on.

Two camera rigs ship. The display rig fits the scene's bounding box to a virtual display and orbits it, which is the behaviour a 3D panel expects from arbitrary content. Version 1.26.0 added a camera rig for photo lifted splats, which opens the scene at the original capture camera's viewpoint and conserves that camera's intrinsics rather than substituting a generic projection.

Version 1.27.0 fixed washed out colours on sRGB swapchains against OpenXR runtime version 2.18.0 and later. The release notes name Linux, macOS through MoltenVK and Windows as affected and Android as unaffected, which is one of three independent confirmations that the project targets all four platforms. The others are the release assets themselves, which are .deb, .apk, .pkg and .exe, and the internal review of the change covering all four builds.

The repository README and the GitHub repository description are both behind on that point and should not be read as a platform list. Earlier statements of Windows only, and of Windows, macOS and Android, were superseded. DisplayXR has been demonstrated running against a Leia DS1 panel.
