Can we have a boolean in material.xml (true for runways) and the value in some property ? This way we can disable it or set the value for the filtering level on the command line. Because you can not hard code '8', this will give very different fps depending on the hardware.

Filtering can be switch on and controlled as per SGMaterial. 1. == default off Please note that only powers of two are valid. I have applied that as is, but I am very open for improvements in the way it could be configured. Also note that we only filter runway textures in this way not all possible textures. That might already cover many concerns with any possible framerate impact ...

Re: [Flightgear-devel] Anisotropic Filtering for Runways
Hi, thanks for the feedback. I will look into adding a widget to the rendering options for limiting filtering (maybe along with a command line option). The filtering8.0/filtering is clumsy, too.

Re: [Flightgear-devel] Anisotropic Filtering for Runways
Curtis, Note that anisotropic filtering makes all the textures look sharper when viewed close to edge on ... terrain in the distance, aircraft markings, etc. I'm still not convinced the doing this per material in the materials.xml file is the best approach. It would be nice to be able to have anisotropic texture filtering for loaded models and everything else as well ... I'd still be more in favor of a single global setting that affects the entire sim. I did the materials approach because I didn't want to harm older graphic cards too much. But since most of the posters like to have a global control I see no point in applying it only to certain materials for now. Right now I am hacking the Rendering Options panel.

Olaf In fgIdleFunction(), this line glTexEnvf( GL_TEXTURE_FILTER_CONTROL_EXT, GL_TEXTURE_LOD_BIAS_EXT, -0.5 ) ; should be disabled when we use anisotropic filtering (because it becomes useless and because in all cases it ruins the mipmaping of buildings walls). Also since the anisotropic filter parameter must be applied to each textures (and it's hard to do that if we don't have a list of existing textures), you can rememder the user that the option will only be applied on the next launch of FG.
