Musing about stereoscopic plotting.

[Daniel J S. <dan...@ie...>]

With regard to what I wrote in the previous post about better 
organization of 2D/3D data aiding new feature development, one could 
think of the 2D plot as just a projection of 3D data (with added axis 
decoration capabilities not suitable for 3D).

This brings to mind something I've wondered about from time to time, 
which is whether stereoscopic plotting (i.e., two plots side by side, 
not "stereographic" plotting) is something that would be useful to maybe 
a few fields like protein analysis, etc.  It would be more than merely 
doing a multiplot, for example.  Rotating the mouse would rotate the two 
images in concert to give the illusion of rotating a 3D object.  I've 
limited experience with stereoscopic "projection", and maybe it is more 
difficult than I imagine.  (There probably not only needs to be viewing 
angles, but depth of view, or maybe that's called parallax.) 
Nonetheless, it would be interesting.  But again, gnuplot internals 
would need to be revamped for something sophisticated like that.
