I fear that's pretty much impossible by design.  The gnuplot terminal 
API is expressly 2D-only, whereas OpenGL is 3D by design.

Faster than the existing mouse interaction?  Without breaking visibility 
of tick labels, axes or the key because they rotate to entirely the 
wrong place?  That might prove trickier than you anticipate.

A loong time ago, there was a suggested patch to add a VRML terminal 
driver.  It kind-of worked, but it was extremely intrusive and basically 
didn't integrate with any of gnuplot's 3D routines at all.  It was 
hardly any improvement over post-processed 'set table' output.
