Two Pivot Mirrors Around a Central Vanity Mirror (Top-Down Reflection Simulator)

Top-down view: bottom wall has the central mirror. Left short wall extends 11 inches upward. Adjust two side mirrors and see if the eye can see the back of the head via 2-bounce reflections.
FAILNo valid reflection path found
Coverage0%
Rays: green = valid reflection path (hits mirror segments and is not blocked by walls). red = tested but invalid.
Paths tested: Eye → Side → Central → Back-of-Head, and Eye → Central → Side → Back-of-Head (for each side mirror).
Note about pitch and height: pitch and vertical placement are used as a plausibility filter (simple vertical bisector heuristic). The core ray tracing is in the top-down plane.
Controls (always visible)
Default side mirror specs are pulled from the Wayfair listing for Winston Porter "Corrente Pivot-N-View" mirror: overall 26" H × 16" W × 3" D, mirror (reflective) 22" H × 14" W, tilt listed, and "360 degrees" swivel described.

Environment

Units are inches. Coordinate system: origin is the corner where walls meet. X increases to the right. Y increases upward (away from the bottom wall).

"Exquisitely beautiful but statistically typical" head model: an ellipse in top-down (width and depth sliders), with the eye point near the front of the ellipse facing the central mirror.

Side Mirror Defaults (Wayfair listing)

Default reflective surface: 14" W × 22" H. Overall: 16" W × 26" H × 3" D. The listing describes a swivel "adjustable at any view (360 degrees)" and "tilt" adjustability, but does not specify hard stop limits. Assumption: yaw can rotate freely ±180 degrees; pitch is user-adjustable ±45 degrees as a conservative practical range.

Left Side Mirror

Position is the mirror center in the top-down plane. Yaw rotates the mirror around a vertical pivot (top-down). Pitch and height are used for a simple vertical plausibility check.

Right Side Mirror

Debug / Visibility

Coverage is estimated by sampling points around the back half of the head ellipse. PASS means at least one target point is visible via a valid 2-bounce path.
