Here is some code to translate the HUD with the eye vector
for those that want to play :-)
add to mouse.cxx
#define TRANSLATE_HUD
// temporary hack until pitch_offset is added to view pipeline
void fgTranslateHud( void ) {
#ifdef TRANSLATE_HUD
if(mouse_mode == MOUSE_VIEW) {
float y = 0.0f;
int ww = fgGetInt("/sim/startup/xsize");
int wh = fgGetInt("/sim/startup/ysize");
y = _mY - (wh >> 1);
float x = globals->get_current_view()->get_view_offset()
* SG_RADIANS_TO_DEGREES;
if( x < -180 )
x += 360;
else if( x > 180 )
x -= 360;
x *= ww/180.0;
// x *= ww/360.0;
glTranslatef( x*ww/640, y*wh/480, 0 );
}
#endif // TRANSLATE_HUD
}
add to hud.cxx
extern void fgTranslateHud(void);
void fgUpdateHUD( GLfloat x_start, GLfloat y_start,
GLfloat x_end, GLfloat y_end )
{
.......
glLoadIdentity();
gluOrtho2D(x_start, x_end, y_start, y_end);
glMatrixMode(GL_MODELVIEW);
glPushMatrix();
glLoadIdentity();
+ fgTranslateHud();
.....
}
