Stereopairs and other techniques are useful for visualizing three dimensional objects more comprehensively, as are animated presentations. Experience shows that the combination of a front view with a side view, both taken as parallel projections, is as effective as any when it comes to actually working with three dimensional objects. Display of such a pair of views has a high priority in the further elaboration of GEOM. Of course, the other presentations have artistic merit and contribute in their own way to visualizing objects, so their further development must also be considered.
