In FlightGear, many shaders are used through the so called "effects" framework, to learn more about that, see $FG_ROOT/Docs/README.effects | |||
While you can certainly change a few numbers here and there to see how that affects the final outcome, you'll find that understanding the underlying maths will be very helpful - for that, see the links that Thorsten posted, or those that you can find inside those shader files. | |||
so called "shaders" that will be normally run by your GPU: http://en.wikipedia.org/wiki/OpenGL_Shading_Language | |||
To give you some background on shaders in FlightGear, please see: http://wiki.flightgear.org/Shaders | |||
These are plain text files that are compiled by your GPU's driver, transparently in the background. | |||
To understand a few basics such as the differences between FRAGMENT and VERTEX shaders, see http://wiki.flightgear.org/Howto:Shader_Programming_in_FlightGear | |||
