Composition in Perspectives

Abstract

Composition is a key element of image aesthetics. However composition is hard to control when working in three dimensions to create a two dimensional image. A framework that derives perspective from a planar pattern is proposed and implemented. The third dimension is elevated from a tiled floor into a planar square pattern. Key points on the image allow users to modify the spatial geometry of the scene. Thus, this paper presents a new view on perspective, where there is no concrete third dimension, but where the third dimension is inferred from lines and points in the image plane from which apparent depth relationships of the scene are constructed. In describing the framework, the computational relation between elements such as vanishing point, distance points and floor lines inside the geometric grid, are exposed to demonstrate the characteristics of building a realistic, yet, composed, image based on the practices of Renaissance painters.
