Howto:Shader programming in FlightGear

Switch to {{fg root file}} to fix the broken Gitorious link.
In FlightGear, these files can be found in the <code>Shaders</code> subdirectory of the base package, in essence <code>$FG_ROOT/Shaders</code>.
For a list of currently available shaders, you may want to take a look at:{{fg/fgdata/trees/master/root file|Shaders}}.
So, shaders generally go around in pairs - one shader (the ''vertex shader'') is a short program that takes in one vertex from the main CPU and produces one vertex that is passed on to the GPU rasterizer which uses the vertices to create triangles - which it then chops up into individual pixel-sized fragments.
