水面完美倒影：2.5 / 2 / Banana / Reve 同题烤炉

Prompt

GPT Image 2.5 vs. GPT Image 2 vs. Nano Banana Pro vs. Reve. Same prompt.

2x2 grid,1:1 AI picks stunning different subjects: Π = reflecting plane: point q, unit normal m
R(x) = x − 2((x−q)·m) m (reflection across Π)
reflected image = scene imaged by the VIRTUAL camera R(C) ; every real feature f has twin R(f)

RENDERED
• reflection is a BIJECTION of the scene across Π ; occlusion order reverses
• points on Π are fixed → the waterline is self-coincident
• chirality FLIPS — text and hands are mirror-reversed
• a vertical object inverts about the waterline ; base-of-object meets base-of-reflection exactly on Π
• perspective in the reflection is that of R(C): the same vanishing points, mapped

READ OFF
• k real↔reflected correspondences: each pair's perpendicular-bisector plane must be the SAME Π
• reflected height / compression is lawful with view angle, not free
• everything in front of Π that R(C) can see appears — and nothing else

CONSISTENCY
recover (m̂, q̂) from correspondence pairs — must coincide ; check handedness of every reflected glyph
FORBIDDEN : a reflection containing an object with NO real pre-image (or dropping one plainly in front) ;
signage readable forward in the glass ;
reflected pose / expression differing from the subject ;
a floating reflection whose base does not meet the object on Π.
