A Vignette-Style Background Modeling System Using Inverted Triangular Composition

“Vignette-Style” is a diorama-like illustration that condenses a unique perspective of a work. It is characterized by a composition that looks like a three-dimensional cutout of a part of the scene. It is important to determine how to arrange the background diorama and characters in a composition to make a character more attractive. We developed a system that allows users to easily create backgrounds with an inverted triangle composition.
