This allows us // to transform world space to eye space for view frustum culling. // // Revision 1.7 1998/05/13 18:29:59 curt // Added a keyboard binding to dynamically adjust field of view. // Added a command line option to specify fov. // Adjusted terrain color. // Root path info moved to fgOPTIONS. // Added ability to parse options out of a config file. // // Revision 1.6 1998/05/06 03:16:26 curt // Added an averaged global frame rate counter. // Added an option to control tile radius. // // Revision 1.5 1998/05/03 00:47:32 curt // Added an option to enable/disable full-screen mode. // // Revision 1.4 1998/04/30 12:34:19 curt // Added command line rendering options: // enable/disable fog/haze // specify smooth/flat shading // disable sky blending and just use a solid color // enable wireframe drawing mode // // Revision 1.3 1998/04/28 01:20:23 curt // Type-ified fgTIME and fgVIEW. // Added a command line option to disable textures. // // Revision 1.2 1998/04/25 15:11:13 curt // Added an command line option to set starting position based on airport ID. // // Revision 1.1 1998/04/24 00:49:21 curt // Wrapped "#include " in "#ifdef HAVE_CONFIG_H" // Trying out some different option parsing code. // Some code reorganization. // //
