Analyzing the laser-light reflection from human hair fibers. II. Deriving a measure of hair luster.
Hair shine or luster is perceived as an important, though analytically somewhat elusive, attribute of beauty, primarily associated with clean and healthy hair. Principles for the assessment of hair luster are developed that are consistent with the practical situation. These principles are related to the components of light, specularly and diffusely reflected from single hair fibers, as measured...
متن کاملPhotorealistic Rendering of Human Hair Fibers
Photorealistic rendering of human hair has been a challenge task in computer graphics for many years. These challenges include coming up with a practical yet accurate light scattering model for individual hair fibers, handling the complex geometry of large number of hair fibers, properly simulating the global illumination and complex interaction of light and shadows between the hair strands, an...
متن کاملImportance Sampling of Reflection from Hair Fibers
Hair and fur are increasingly important visual features in production rendering, and physically-based light scattering models are now commonly used. In this paper, we enable efficient Monte Carlo rendering of specular reflections from hair fibers. We describe a simple and practical importance sampling strategy for the reflection term in the Marschner hair model. Our implementation enforces appr...

متن کاملA Data-Driven Light Scattering Model for Hair
We present an implementation of the [Marschner et al. 2003] model for importance sampling light reflected from hair. The implementation makes use of a version of Adaptive Importance Sampling (AIS), specialized to fit easily sampled distributions to BCSDFs. Our model is novel among importance sampling implementations in that it includes all the features of Marschner such as eccentricity for elli...
