• Examples of filtering standard wavefront format obj files as used the RAMI simulation experiments.
• User examples: user-submitted examples of various librat use.
• Examples showing how cloning works in a librat object file.
• Examples of basic librat / start operation.
• Examples of the librat lidar simulation mode.
• Detailed set-up, installation and simulation example for ESA 3D RT modelling of savannas.
