Build for a specific display
A spatial display adds another output target to a web application. It does not remove the need for an ordinary screen, accessible controls, or a performance budget. Before choosing a renderer, identify the display model, host operating system, supported browser and software bridge.
Looking Glass documents a WebXR library for its light field displays. Its current product page distinguishes those displays from its Hololuminescent range, which has a separate integration path. “Holographic” is therefore not a sufficient compatibility specification. Looking Glass WebXR requirements.
What a quilt contains
A quilt arranges multiple views of a scene into one image. Looking Glass uses this representation for still images, video and parts of its rendering pipeline. The tile arrangement and calibration must match the target device; an arbitrary high-resolution image will not produce the intended result. Quilt format introduction.
Multiple viewpoints also change the rendering budget. A scene that works well from one camera can become expensive when rendered from several perspectives. This does not mean every display uses the same number of views or that each view has the full resolution advertised for the physical panel.
Light field, stereoscopic and volumetric displays use different optical approaches. Evaluate depth range, viewing positions, text legibility and comfort on the actual device. A product label alone does not establish that a display resolves every accommodation or eye-strain concern.
Use the documented browser integration
The maintained Looking Glass repository names the package @lookingglass/webxr and its LookingGlassWebXRPolyfill entry point. Its setup requires a connected display and running Looking Glass Bridge. It documents Three.js, Babylon.js and PlayCanvas integration. Maintainer setup and examples.
A useful implementation sequence is to run the matching official sample first, record its dependency versions, then replace its scene content. Preserve the sample's session and window handling until the display is working. Avoid mixing an older sample's imports with a newer engine release without checking compatibility.
This article does not present an untested custom renderer as a working SDK example. The hardware integration has not been executed here.
A small acceptance experiment
Start with one opaque object, a depth reference and a text label. Record the display model, quilt settings, browser, GPU and frame timing. Add one expensive feature at a time: transparency, shadows, animated geometry, then larger datasets.
For a 3D scatter plot, compare three tasks on the flat screen and spatial display: finding an outlier, understanding a cluster and reading its exact value. Keep selection details in an ordinary HTML panel. A visually compelling point cloud is not useful if the user cannot identify a selected record.
When a display disconnects, retain the scene's ordinary camera view and controls. Stop unused render loops and release session resources. Treat display reconnection as a recoverable state rather than reloading the whole application.
Choosing a worthwhile use case
Use spatial output where depth helps a specific task: inspecting geometry, comparing spatial relationships or presenting a model to a group. Validate that benefit with representative content and users. Claims of mainstream adoption, indistinguishable realism or guaranteed smooth playback require evidence beyond a product demonstration.
