Einstein wrote : “ It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do ” (wave–particle duality)
There are wave-particle properties of light. On photoreal visualization, we see only wave properties of light, photo from CAD scripts render, and where are particle properties? Similar as for example thermal analysis, but other, by simulating physics of light by standard rendering software of n- enlargement bounces could envoy particle properties, as from glass heart object get similar shape as Calabi Yau variety assumption.

By simulation physics of light by rendering software as standard render as of n-enlargement bounces from glass heart object get similar shape as Calabi Yau variety assumption. Bottom view we could see similar shape as Klein bottle, side view we could see similar shapes as cut of Möbius band and top view we could see black gap. This new method calling RTDG technology could help String theory with question of using how many dimensions.
