Virtual Reality with Qt Quick 3D
summary
Qt Quick 3D integrates VR by wiring Qt 6 RHI to OpenXR, creating an xr view that replaces the window and uses a render control to draw into headset swapchains (e.g. Quest 2 triple-buffered 1440×1584 targets) at a hard budget (typically 72 fps), rendering the scene twice (one pass per eye). Backends supported: OpenGL/OpenGLES, Vulkan, Direct3D. Physics uses Bullet 3D for collisions and grab/throw interactions. Input works via controller poses and a virtual mouse; virtual keyboard focus still fails without a real window.
