Abstract:In this paper we present our developed bidirectional reflectance distribution capturing pipeline. It includes a constructed gonioreflectometer for reflectance measurements; as well as extensive software for operation; data visualization and parameter fitting of analytic models. Our focus is on the flexible user interface; aimed at material appearance creation for computer graphics; and targeted both for production and research employment.

Key challenges have been in providing a user friendly and effective software for functioning in a production environment; abstracting the details of the calculations involved in the reflectance capturing and fitting. We show how a combination of well-tuned tools can make complex processes such as reflectance calibration; measurement and fitting highly automated in a fast and easy work-flow; from material scanning to model parameters optimized for use in rendering. At the same time; the developed software provides a modifiable interface for detailed control. The importance of having good reflectance visualizations is also demonstrated; where the software plotting tools are able to show vital details of a reflectance distribution; giving valuable insight in to a materials properties and a models accuracy of fit to measured data; on both a local and global level.
