Notes on the Ward BRDF

BRDF-Shop: An artistic tool for creating physically correct BRDFs

We present an interface for quick and intuitive development of arbitrary, but physically correct, Bi-directional Reflectance Distribution Functions, or BRDFs. Our interface, referred to as BRDF-Shop, provides artists the ability to create a BRDF through positioning and manipulating highlights on a spherical canvas. We develop a novel mapping between painted highlights and specular lobes of an e...

Comparison of the training status of medical students of pediatric ward based on their logbooks

Introduction: Logbooks show whether medical students have been exposed to a particular disease and whether they are able to perform particular practices or not. To evaluate the training status of the medical students in the pediatric ward of Shiraz University of Medical Sciences, the data about the students’ knowledge of different diseases in different parts of the pediatric ward in 2011 was co...

MCSL BRDF Database for Art Painting

In this report we will present a practical working pipeline for building a BRDF database of art painting. We use the MCSL Imaging Goniospectrometer collect BRDF measurements for 24 panels, each of which consists 25 different patches. For each patch on each panel, we recover the diffuse surface normals using photometric stereo method and fit the data using analytic BRDF models, such as Ward and ...
