Input

Input is currently Win32-backed and intentionally small.

Flow

  • Win32Window translates window messages into InputState.
  • AquariumHost begins each input frame, pumps messages, then updates runtime.
  • AquariumRuntime passes input into OrbitCameraRig.
  • The renderer receives the updated camera and Grid frame as constants.

Controls

  • Middle mouse drag: orbit camera around the Grid center.
  • Mouse wheel: exponential zoom.
  • Right mouse drag: pan along the Grid plane.
  • WASD: pan along the Grid plane.

The camera target remains the Grid center. Panning moves that shared target; orbiting changes only yaw/pitch; zoom changes only camera distance and therefore Grid radius.
