Tutorials

The following provides a several tutorials to help in getting started with the core Helios system and associated plug-ins. Programs associated with the tutorials can be found in the "samples" directory. Assuming that you have the necessary dependent software installed (see Install and Set-up), the samples/tutorials can be built by changing into the "build" subdirectory for the tutorial, then running the command "cmake .." followed by "make". This should generate an executable file with the same name as the tutorial directory.
