Generalized Image Acquisition and Analysis

Dynamic Display of BRDFs

This paper deals with the challenge of physically displaying reflectance, i.e., the appearance of a surface and its variation with the observer position and the illuminating environment. This is commonly described by the bidirectional reflectance distribution function (BRDF). We provide a catalogue of criteria for the display of BRDFs, and sketch a few orthogonal approaches to solving the problem in an optically passive way. Our specific implementation is based on a liquid surface, on which we excite waves in order to achieve a varying degree of anisotropic roughness. The resulting probability density function of the surface normal is shown to follow a Gaussian distribution similar to most established BRDF models.

Overview:

In the first part, this lecture covers advanced display technology such as projector arrays, projection onto non-planar surfaces, field-of-view extension, depth-of-field extension, dynamic range extension, and 3D display technology, focussing on glasses-free techniques. In the second part, we will discuss holographic techniques, recording principles, noise issues (speckle), and computational aspects for Computer Generated Holography.
