A chance for me to pick Steve's brains :-)

Runways are the classic application for anisotropic texture mapping aren't 
they?  Angus Dorbie's demos for Performer show it pretty nicely at 
http://www.sgi.com/software/performer/brew/anisotropic.html

Interestingly, Cass Everitt from nVidia has recently posted a whitepaper on 
anisotropic texture mapping in OpenGL (in MS Word format of course...) at:

http://www.nvidia.com/Marketing/Developer/DevRel.nsf/bookmark/9944854B211F6FC98825691F005C7EEF

plus a simple demo showing GL_EXT_texture_filter_anisotropic on nVidia 
hardware.  Source is available, and I think it's just a GLUT application so 
it might build under Linux.

Would anisotropic texturing help Curt's problems in Flightgear?

Thanks,
