+#### Graphics
+For compatability reasons the system supports two different methods for rendering the 3D graphics; _OSMesa_ and _Pangolin_. The default method is _Pangolin_.   
+
+* **Pangolin**  
+Download Pangolin's source code from the project's [GitHub page](https://github.com/stevenlovegrove/Pangolin).  
+Follow the instructions on that page for how to build the library. Put the created library file _libpangolin.so_ in a place where it can be found by the linker. On Ubuntu this includes the directory _/usr/lib_.
+
+* **OSMesa**  
+Configure the system to use _OSMesa_ by removing the following line in the build configuration file _MR-Leo-server.pro_ before building:  
+```CONFIG += USE_PANGOLIN```
  
 ### Building
 1. Make sure that you have the build environment set up.
