Hi,

> In V6, it is possible to rotate a ParametricPlot3D (or the like) in
> real time. Is it possible to determine what ViewPoint->() value a
> rotation results in?

This is one of assumingly infinitly many possibilities:

DynamicModule[{vp = {1.3, -2.4, 2.}},
  Column[{
    plot =
     Plot3D[Sin[x y], {x, 0, 1}, {y, 0, 1}, ViewPoint -> Dynamic[vp],
      ImageSize -> 500],
    Dynamic[vp]
    }]
  ]

hth,

albert
