If the parameter is changed to 2, a local orthonormal system based on the normals of the surface is constructed. This no longer takes the splash vector consistently into account and works poorly for surfaces which are flat in the (xy)-plane, but gives decent result for side windows. | If the parameter is changed to 2, a local orthonormal system based on the normals of the surface is constructed.

== Interior | == The ALS interior model effect == | ||
Since the interior of a cockpit is a large part of what a pilot gets to see in-flight, but this interior represents a rather special situation (light is reduced as it falls through windows, it may have artificial light, there is never any fog or haze,...) ALS offers a separate effect to specifically render the interior of a plane. | |||
This effect also includes optional features which will be available at higher quality settings of the model shader. | |||
=== Interior shadows and tinted glass effect === | |||
With FlightGear version 3.5 and above, ALS now supports interior shading; i.e. the sun shining through the windows and casting shadows on the panel. | With FlightGear version 3.5 and above, ALS now supports interior shading; i.e. the sun shining through the windows and casting shadows on the panel. | ||
