Lighting design is an important topic of 3D scene design. There are many functions that lighting assumes in game environments, including directing attention, visibility, evoking emotions, setting atmosphere, and providing depth. Due to the unpredictability of interactive environments, current lighting design models do not adequately adapt the lighting to serve these aesthetic and communicative ...

We investigate how lighting can be used to influence how the personality of virtual characters is perceived. We propose a character-centric lighting system composed of three dynamic lights that can be configured using an interactive editor. To study the effect of character-centric lighting on observers, we created four lighting configurations derived from the photography and film literature. A ...

The Pearl is a multi-modal computer interface initially conceived as an interactive prop for a multi-artistic theatrical performance. It is a spherical hand-held wireless controller embedded with various sensor technologies and interactive lighting. The lighting was a key conceptual component in the instrument’s creation both as a theatrical prop and also as an interface for musical performance...

Modeling and visualization of natural and realistic outdoor ecosystems like forests or meadows remains a highly challenging task in computer graphics. Convincing and non-artificial scenes require many thousands to millions of plants, each modeled with a high degree of geometric, shading, and lighting detail. At the same time many applications demand interactive rendering at high fidelity. In th...

We present a framework for interactive lighting design based on linear re-rendering. The rendering operation is linear with respect to light sources, assuming a xed scene and camera geometry. This linearity means that a scene may be interactively re-rendered via linear combination of a set of basis images, each rendered under a particular basis light. We focus on choosing and designing a suitab...

In the field of aircraft design, interior illumination increasingly becomes an important design element. Different illumination scenarios inside an aircraft cabin are considered to influence the mood of air passengers, help passengers to be better prepared for time lags and to create an overall positive environment. Consequently, a physically correct and realistic lighting simulation becomes es...

Lighting design in computer graphics is essentially not a random process but one driven by both a technical and aesthetic appreciation of lighting. In some applications, the result of the lighting design process is a 2D image derived by rendering a 3D scene. Users with limited understandings of manipulation of lighting parameters may have difficulties in properly modifying the lighting paramete...
