In the context of non-photorealistic imaging, such as digital cel animation, lighting is symbolic and stylized to depict the scene’s mood and the geometric or physical features of the objects in the scene. Stylized light and shade should therefore be intentionally animated rather than rigorously simulated. However, it is difficult to achieve smooth animation of light and shade that are stylized...

Simulating indirect lighting effects has been a challenging topic in many real-time rendering and design applications. This paper presents a novel method, based on precomputed radiance transfer, for rendering physically based, multi-bounce indirect lighting in real-time. Our key idea is to represent both the direct lighting and precomputed diffuse indirect transfer using a spectral mesh basis s...

A field study was conducted at three clothing stores to validate previous laboratory findings indicating that colored LEDs used as background display lighting could: 1) lower the power demand of accent lighting by up to 50 percent; and 2) provide greater attention capture and visual appeal than current lighting practice. Blue LEDs provided a colored background for window mannequins by illuminat...

Abstract This study presents the development, analysis and assessment of residential lighting load profile using computational intelligence based modelling Adaptive Neuro Fuzzy Inference System (ANFIS) and Neural network (NN) models for prediction (forecasting) and evaluation of lighting load and initiatives. Factors considered in the development of the models include natural lighting, occupanc...
