The ALS Landing Lights/Spotlight is a good example for showing how to incorporate a shader effect into [[Flightgear]] as it touches many parts of the visuals we see and many parts of the coding pipeline. | The ALS Landing Lights/Spotlight is a good example for showing how to incorporate a shader effect into [[Flightgear]] as it touches many parts of the visuals we see and many parts of the coding pipeline. | ||
