is there any refeernce site or tutorials that details how to make the "head view" follows the mouse movement like in quake or other similiar games?

thanks

Just measure how long the mousepointer has moved since last frame and use that as rotation value (addative).

in quake3(probably in other too) they interpolate mouse movement between present and previous frame, so it looks a bit smoother (but this way you loose some accuracy)....
and of course mouse movement is somehow scaled by frametime..

First I also thought you'd need to scale the mouse movement by the frametime, but it turned out it wasn't so!.. Or atleast it looked wrong to me when I did.

If you think about it, if a frame takes longer to draw, the user can move the mouse longer before the program measure it... It becomes "naturally" multiplied http://www.opengl.org/discussion_boards/ubb/smile.gif

yes, that's true...
for example when frametime == 1sec, you'll see what you should see past second http://www.opengl.org/discussion_boards/ubb/smile.gif
but actually there's no way to avoid it - what makes it unnoticable in games is high fps, otherwise it's a pain anyway
