Automatic Lighting Design
Lighting has a crucial impact on the appearance of 3D objects and on the ability of an image to communicate information about a 3D scene to a human observer. This paper presents a new automatic lighting design approach for comprehensible rendering of 3D objects. Given a geometric model of a 3D object or scene, the material properties of the surfaces in the model, and the desired viewing paramet...
متن کاملImage-Based Lighting Design
In this paper, we present a lighting design framework for neardiffuse real objects, starting from a set of prerecorded photographs of an object under various lighting conditions. Light sources are placed at fixed positions around an object, for which the intensities are to be determined. Using existing digital imaging software, the lighting designer paints the desired illumination distribution ...
متن کاملPerception-based Lighting Design
Perception-based lighting design approaches model image quality using a cognitively grounded objective function which is in turn optimized through manipulation of the lighting parameters of a scene. We present, and demonstrate, a detailed implementation of perception-based lighting design, including the application and evaluation of stochastic optimization using genetic algorithms.
متن کاملDesign Criteria for Tunnel Lighting
There are many mountains in the longitudinal center of Taiwan, which slow down transportation between the west and east in Taiwan. In order to solve this problem, Taiwan’s government decided to build a highway and an expressway between these two areas, which would include tunnels as part of the project because tunnels are more dangerous than the open road, how to safely enter, pass and leave tu...
متن کاملHybrid Solid-State Lighting Design
The transition from incandescent lighting to more energyefficient options is projected as a major opportunity for solid-state lighting (SSL.) The current prevailing technology for white-light SSL uses a nitride semiconductor blue LED combined with a downconverting YAG:Ce yellow phosphor. The residential use of LED lights presents challenges beyond efficiency, because of very-high color-renderin...
