چکیده

In this paper we describe simple design of a kaleidoscope used for measuring the bidirectional reflectance distribution function with aim to obtain the bidirectional texture function of various surface samples. The first prototype of the kaleidoscope was designed in symmetrical configuration with four tapered mirror walls. We discuss the influence of different design parameters with respect to expected results. The proposed kaleidoscope was manufactured and his performance evaluated.

Device for convenient measurement of spatially varying bidirectional reflectance.

Capturing surface appearance is a challenging task because reflectance varies as a function of viewing and illumination direction. In addition, most real-world surfaces have a textured appearance, so reflectance also varies spatially. We present a texture camera that can conveniently capture spatially varying reflectance on a surface. Unlike other bidirectional imaging devices, the design elimi...
