Instead of a raster or vector approach how about an array of lasers all with fixed focal lengths that project into a predetermined 3D viewing space? Kind of like a 3D LCD setup. Tbh they've probably already thought of these ideas. As Obi-Wan says: "Patience".
I think that's a good idea, but wow too expensive! Why not have a laser for each voxel in 1000x1000x1000 space? :-) Seriously, that may be the kind of breakthrough needed for this research to be commercially viable.
