「逆遠近法」（"reverspective"）はアーテイスト Patrick Hughes の作品で有名。日本では、関西大学の Norman Cook 先生が研究している。

もちろん金閣は谷折り。しかし、この方向から見ても何か変に見える。

Dear XYZ,

My name is Akiyoshi KItaoka, one of the committee members of Visiome Platform.

The dragon illusion is one of the commercial creations of Grand-Illusion.com.

In general, this kind of illusion can be called “reverspective”. There are

at least two types of reverspective. One type is a trompe l’oeil which uses

line perspective, e.g. the Ames trapezoid, Patrick Huges’ artworks,

or my production shown below. Usually, “reverspective” refers to

this type.

"Illusory cube"

This physically concave object tends to appear to be convex.

The other type is called ‘’hollow face illusion”, a phenomenon that a concave mask appears to be a convex face.

This illusion is thought to be specific to face percpetion.

I imagine these two types of reverspective cooperatively play a role in the dragon illusion,

though I do not know any research articles which discussed this point.

Best regards,

Akiyoshi
