Pa allax e ec s: In e ing he space conca i y Fi s ques ion o be answe ed is how i is possible o in e he space conca i y. Pseudoscopy is he physical p ope y explaining ha issue.

So, objec s close o he holog aphic pla e/ ilm du ing he egis a ion phase appea o be a away when he holog aphic image is econs uc ed. When, ins ead o se e al objec s, he e is only one, he esul is he olume in e sion, i.e. making con exi y o u n in o conca i y and ice e se. Such e ec has been widely used in adi ional sculp u e and elie s h oughou he a his o y om ancien o con empo a y p ac ices. Fo example, he Egyp ian ones in he walls o he py amids ( igu e 11); o Subi ach’s sculp u es placed in he acade o he Sag ada Familia Ca hed al designed by Gaudi and buil in Ba celona ( igu e 12). Posi i e (con ex) o nega i e (conca e) olumes can be achie ed and showed in a e y di e en way depending on he ligh sou ce posi ion illumina ing hem. Figu a 11. Egyp ian Temple a Dende a Figu a 12.
