Get back to the setup.

The first load downloads substantial 3D assets and textures. Allow it to finish on a stable connection. Check whether a loading error appears, and retry once if necessary. Reloading discards your current pose.

The lab requires a working WebGL graphics context and supported framebuffer formats. Check that hardware graphics acceleration is enabled in your browser, then restart the browser. If it still fails, save a diagnostic report below and record the visible error. There is no substitute image when the renderer is unsupported.

Press Escape or use the fullscreen control to leave fullscreen, then open Settings. Browser and embedded-preview fullscreen behavior varies; include the browser and steps in your report. Fullscreen support is still part of the device acceptance review.

Choose Patient View to recenter the camera without resetting the pose. Room View shows the wider equipment layout. Reset patient changes the pose, so use it only when you want to restart.

Settings changes preview immediately but need Save. Saving with a category expanded saves that category; saving with all categories collapsed saves all categories. Private browsing, blocked storage, or clearing site data can remove saved settings.

Patient contact uses sampled bone and equipment surfaces; equipment-to-equipment contact still uses conservative bounds. Movement away from the obstacle should remain possible. Contact is not a clinical or soft-tissue simulation.

The lab has a narrow-screen Camera / Body / Tube / Part selector and stacked panels. Viewport and pointer checks have passed; actual touch, pinch, phone performance and the on-screen keyboard still need real-device review. A desktop or laptop is the current review baseline.

Unsaved positioning lasts for the current session. In Free mode, use the save icon beside the position name to keep a library position’s setup and custom name in this browser. Reopen that record from the library to load it. Capture saves only the image. Undo and redo restore positioning during this session; Student tasks and exposures are not saved across reloads.
