In this paper, we propose a novel real-time Bidirectional Reflectance Distribution Function (BRDF) shading interface for creating isotropic BRDFs in image-based lighting.  ...  [3] proposed a BRDF-Shop, which is an interface for creating physically-correct BRDFs through positioning and manipulating highlights on a spherical canvas.  ...  Representing homogeneous materials in physically-based rendering systems is generally achieved by the Bidirectional Reflectance Distribution Function, BRDF, introduced by Nicodemus et al. [4] .  ...

BRDFLab: A general system for designing BRDFs [article]

Adrià Forés, Sumanta N. Pattanaik, Carles Bosch, Xavier Pueyo
2009 Spanish Computer Graphics Conference  
We plan to use this as a tool for simulation and modeling of complex physically-based BRDFs, and thus provide access to a larger variety of material models to the rendering community.  ...  BRDF-Shop [CPK06] , for instance, is an interface to create, model and render physically correct BRDFs based on defining the highlights of the desired model onto a spherical canvas.  ...  In spite of the extensive research in the field, there still does not exist a common platform for visualizing and working with different types of BRDF (Bidirectional reflectance distribution function),  ...
