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This book gathers previously unpublished essays by one of the greatest historians of the twentieth century.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 ...

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 ...

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

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.

The wide availability of mobile devices capable of computing high fidelity graphics in real-time has sparked a renewed interest in the development and research of Augmented Reality applications. Within the large spectrum of mixed real and virtual elements one specific area is dedicated to produce realistic augmentations with the aim of presenting ...

Pre‐convolved Radiance Caching
Computer Graphics Forum, 2012AbstractThe incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter‐pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both compute incident indirect light only for a small subset of pixels (the cache), and later interpolate between pixels. Irradiance

Wide generality for optical radiometry can be achieved by treating the basic radiometric quantities as field quantities. The treatment is that of classical ray optics, with emphasis on the geometrical relations involved. It is shown that radiance, defined as N ≡ ∂2P∂Ω cosθ∂A [W·cm−2·sr−1], the radiant flux or power per unit solid-angle-in-the-direction-

Improved radiance gradient computation
ACM SIGGRAPH 2008 classes, 2005We 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.
