[Chimera-users] lenticular images from Chimera

Hi Tanja,

  The command “set fieldOfView 60” will set the horizontal field of view to 60 degrees.  Typically it is around 30 degrees in normal Chimera use.  You can see the value and change using menu Tools / Viewing Controls / Camera.  Another parameter you may be interested in is “eye separation” in the Camera dialog.  It will change the sense of depth — usually I use the cross-eye or wall-eye camera mode (also set in the Camera dialog) to preview on-screen the eye separation effect before making a lenticular image.  A basic problem is not having objects that project out towards the viewer too far.  That usually will not look good due to limitations of the lenticular (and other stereoscopic) technology — basically the physical image (lenticular print or screen) is not wide enough to portray an object close to the viewer’s face because projecting a line through such an object would land outside the bounds of the physical image.

However, we would like to experiment with a wider viewing angle....and I realized that increasing the number of output images decreases only the angle step size, but does not widen the viewing angle. Is there a way to influence this command line???
