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.

Other features:

  • the BRDF-model settings and the graphic display can be saved in a variety of formats.
  • overlay of observation zenith angles for the sensors ATSR, AVHRR, MODIS, MISR, SPECTRA.
  • isotropic and lambert settings

The final version AnisView 1.1 is available from the following Download Location

Download the installer for your operating systems and and save it to a local directory, then

  • Linux: open a shell in the directory where you saved the installer.  Make the installer executable using the command: chmod u+x Then either double-click the installer to get AnisView installed into your HOME-directory, or manually start the installer using: ./ to install AnisView into the current directory.
  • MacOS: double-click the installer (AnisView1.1_mac.dmg) and follow the instructions.
    Note: running AnisView on OS X 10.9 (Mavericks) and later requires installing the latest version of XQuartz
  • MS-Windows: double-click the installer (AnisView1.1_windows.exe) and follow the instructions.

The installation requires no administrator rights. It will extract the entire package, including documenation, manual, disclaimer and the source code, into a single directory.  After the installation, the extracted directory AnisView can be copied/moved to a different location or device, e.g., an external USB-flashdrive.  In this case, please use the included shortcuts to start AnisView from its new location.
