Proceedings of the 2003 symposium on Interactive 3D graphics, 2003 Precomputed Radiance Transfer allows interactive rendering of objects illuminated by low-frequency environment maps, including self-shadowing and interreflections. The expensive integration of incident lighting is partially precomputed and stored as matrices.Incorporating anisotropic, glossy BRDFs into precomputed radiance transfer has been previously ...

Improved radiance gradient computation
ACM SIGGRAPH 2008 classes, 2005 We describe a new and accurate algorithm for computing translational gradients of incoming radiance in the context of a ray tracingbased global illumination solution. The gradient characterizes how the incoming directional radiance function changes with displacement on a surface.

JAMAAll cultures across history engage in arts and cultural activities. But in modern-day society, arts engagement is unevenly patterned. Why is this and what are the factors that prevent people from engaging equitably?

Facial Plastic Surgery, 2004
New injectable agents are expanding the role of fillers in facial soft tissue augmentation. Radiance FN (fine needle) is a new injectable filler composed of calcium hydroxylapatite (CaHA) microspheres suspended in an aqueous gel carrier. CaHA has been used in various forms as a human implant material with an excellent record of biocompatibility.

This book gathers previously unpublished essays by one of the greatest historians of the twentieth century. Ernst Kantorowicz's scholarly expertise ranged from classical antiquity to early modernity and from political pageantry to numismatics. The essays traverse the breadth of his expertise, exploring “radiations” of the themes that were central to ...

Proceedings of the ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games, 2012
Modular Radiance Transfer (MRT) is a recent technique for computing approximate direct-to-indirect transport. Scenes are dynamically constructed by warping and connecting simple shapes and compact transport operators are only precomputed on these simple shapes. MRT ignores fine-scale transport from "clutter" objects inside the scene, and computes light

Applied Optics, 1969
The radiance of clouds is calculated at nine wavelengths in the ir. The single scattering function is obtained by Mie theory from the measured values of the complex index of refraction and with two different drop size distributions. Multiple scattering is taken into account by a Monte Carlo technique which computes the exact three-dimensional paths of ...

The concepts of radiance and fluence are fundamental to the description of a radiation field. The International Commission on Radiological Units and Measurements (ICRU) has defined fluence in terms of the number of the radiation particles crossing a small sampling sphere.
