Lighting Layout Optimization for 3D Indoor Scenes

Abstract

As the number of models for 3D indoor scenes are increasing rapidly, methods for generating the lighting layout have also become increasingly important. This paper presents a novel method that creates optimal placements and intensities of a set of lights in indoor scenes. Our method is characterized by designing the objective functions for the optimization based on the lighting guidelines used in the interior design field. Specifically, to apply major elements of the lighting guideline, we identify three criteria, namely the structure, function, and aesthetics, that are suitable for the virtual space and quantify them through a set of objective terms: pairwise relation, hierarchy, circulation, illuminance, and collision. Given an indoor scene with properly arranged furniture as input, our method combines the procedural and optimization‐based approaches to generate lighting layouts appropriate to the geometric and functional characteristics of the input scene. The effectiveness of our method is demonstrated with an ablation study of cost terms for the optimization and a user study for perceptual evaluation.

Conceptual Framework to Support Personalized Indoor Space Design Decision-Making: A Systematic Literature Review

“…To implement this concept, construction practitioners used natural materials (timber, wood panels) with wide corridors, high ceilings, or wide windows to create openness and incorporate the sun to maintain sustainability [40,41]. Moreover, biological walls and colors such as green and various earth tones attempt to connect people with nature and obtain the psychological impacts of nature-like features in built environments [19].…”

“…However, general frameworks that combine human tendency, technology, and indoor spaces are rarely proposed. This type of framework could serve as an integrated tool to overcome the information and communication limitations between construction practitioners and end-users [1,19,20]. Therefore, this study aims to conduct a systematic literature review to propose a conceptual framework using online databases for supporting personalized indoor space composition decision-making.…”

Saliency Based Illumination Control for Guiding User Attention in 3d Scenes

“…With this approach, structural information is more purely and accurately conferred under the automatically generated light sources. Another study [12] explains a novel strategy in indoor scenes that produces optimum placements and intensities of a series of light. Their method is distinguished by the implementation of objective optimization functions based on the lighting principles which are used in the interior design areas.…”

“…Scene Parameters. 3D scenes vary in terms of conditions, ranging from lights [JL19], camera setup [LMLF15], to contents. Such conditions have a perceptual affect on style.…”
