A radiance environment map pre-integrates a constant surface reflectance with the lighting environment. It has been used to generate photo-realistic rendering at interactive speed. However, one of its limitations is that each radiance environment map can only render the object which has the same surface reflectance as what it integrates. In this paper, we present a ratio-image based technique t...

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...

Visualizing complicated lighting sequences while designing large theatrical productions proves difficult. The author provides some techniques that achieve fast interaction regardless of scene and lighting complexity, even when used with costly rendering algorithms.

Direct volume rendering is a commonly used technique in visualization applications. Many of these applications require sophisticated shading models to capture subtle lighting effects and characteristics of volumetric data and materials. For many volumes, homogeneous regions pose problems for typical gradient based surface shading. Many common objects and natural phenomena exhibit visual quality...

Lighting design is a fundamental aspect of computer cinematography, where it is used to support storytelling by affecting the mood, style, and believability of a scene. Traditionally, lighting has required the tedious adjustment of the large set of parameters that describe complex lighting setups, including lights positions, colors, shapes, etc. This work presents an interactive user interface ...

In 1998 we designed enabling technology and a venue concept that allowed several participants to influence a shared musical and visual experience. Our primary goal was to deliver musically coherent and visually satisfying results from several participants' input. The result, the Interactive Dance Club, ran for four nights at the ACM SIGGRPAH 98 convention in Orlando, Florida. In this paper we w...

Lighting is a fundamental and important process in the 3D animation pipeline. Conventional lighting workflow is time-consuming and labor-intensive. A user must fiddle with a range of unintuitive parameters one by one for a large set of lights continually to achieve the desired effect. LightShop, introduced here, provides the user with an intuitive and interactive interface employing the paradig...

Complex environment lighting has been increasingly used in interactive graphics applications, such as games, to provide higher realism compared to conventional artificial light sources. This paper surveys the real-time rendering algorithms for dynamic scenes under complex environment lighting, and tries to characterize these algorithms by reviewing their base techniques, assumptions, limitation...

This paper proposes an interactive rendering method of cloth fabrics under environment lighting. The outgoing radiance from cloth fabrics in the microcylinder model is calculated by integrating the product of the distant environment lighting, the visibility function, the weighting function that includes shadowing/masking effects of threads, and the light scattering function of threads. The radi...
