Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the illumination effect specified by designers. In this paper, we present an automatic approach for lighting design, in which discrete and continuous optimization of the lighting configu...

There is a need for reliable lighting design applications because available tools are limited and inappropriate for interactive or creative use. Architects and lighting designers need those applications to define, predict, test and validate lighting solutions for their problems. We present a new approach to the lighting design problem based on a methodology that includes the geometry of the sce...

1. Abstract Insufficient lighting is an issue in many poverty-stricken nations. Without proper electric lighting, residents of impoverished communities resort to using potentially hazardous light sources, such as kerosene lamps, candles, and car batteries used to light lightbulbs. Burkina Faso, located in western Africa, is one of the poorest nations in the world, with an annual per capita inco...

Lighting design is an important element of scene composition. Designers use lighting to influence viewers’ perception by evoking moods, directing their gaze to important areas, and conveying dramatic tension. Lighting is a very time consuming task; designers typically spend hours manipulating lights’ colors, positions, and angles to create a lighting design that accommodates dramatic action and...

Automatic lighting design aims to provide users with semi-automated approaches, and easy-to-use tools, to configure lighting for 3D scenes. We present LIGHTOPEX the first fully automatic example-based local illumination lighting design system. Utilizing a wavelet-based lighting design framework, by which image quality is modeled using a cognitively inspired objective function, this approach to ...

Lighting design plays an important role in interactive 3-D training environments; it influences scene perception, scene understanding, attention, visual search, presence, immersion, and emotional involvement. Although there are several research projects that measured the impact of lighting in 3-D environments, little research focused on the development of new lighting design models to enhance t...
