AnisView is an educational software to visualize the Bidirectional Reflectance Distribution Function (BRDF) using one of the two radiative transfer models RPV and MRPV. AnisView has the following features: Graphic display modes: Geometry: an interactive mode to visualize the user-driven illumination and observation geometry. Single BRF value: BRF as a function of the selected geometry and BRDF model parameters. 2-D plot: a cross-cut or plane along a specified azimuthal direction. 2-D contour plot: circular view of the BRDF field including interactive readout of BRF values. 3-D rectangular/polar plot: 3-D visualization of the BRDF field.
