LERF: Language Embedded Radiance Fields
IEEE International Conference on Computer Vision, 2023Humans describe the physical world using natural language to refer to specific 3D locations based on a vast range of properties: visual appearance, semantics, abstract associations, or actionable affordances.

Fast Dynamic Radiance Fields with Time-Aware Neural Voxels
ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia, 2022Neural radiance fields (NeRF) have shown great success in modeling 3D scenes and synthesizing novel-view images. However, most previous NeRF methods take much time to optimize one single scene. Explicit data structures, e.g.

MERF: Memory-Efficient Radiance Fields for Real-time View Synthesis in Unbounded Scenes
ACM Transactions on Graphics, 2023Neural radiance fields enable state-of-the-art photorealistic view synthesis. However, existing radiance field representations are either too compute-intensive for real-time rendering or require too much memory to scale to large scenes.

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.

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 ...

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 ...

American Journal of Physics, 1963
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-
