[vtkusers] desire to save vtk interactive gui 'states' - for later exact same replay

[greg aiken]

I have a need to interactively scroll through a 3d surface (similar to a digital elevation map) - where camera is 'looking downward', where the camera is orthogonal to the plane surface, and where a color map is assigned to the 'elevation' in the 3d surface.  
given that the vtk gui may be interactively zoomed in and out, and that where the camera is viewing may be changed, etc...
is there any ability for me to say, 'i like this specific view of the data set i am now seeing - i need to save the state of this exact viewing situation' (eg,  something akin to taking a snapshot not of the bitmapped pixcelated screen - but rather of the entire state of the vtk environment at that point in time). 
my aimpoint here is to save several such 'states' in a format that would allow me, to at a later point in time, open this same data set in my same vtk application - and then be able to see the EXACT SAME vtk 'snapshot states' that i earlier found to be interesting.
im not a doctor, but suppose such an application  might be so that a doctor making an assessment of a 3d medical volume set might rotate and zoom and choose a specific angle to view some scan at, and then wishing a colleague doctor to see the exact same view of scan to get a different medical opinion about.
does anyone know if this can be done, and or provide a sample code implementation?
perhaps someone has actually done this - and might be willing to code such a vtk app for me.  of course i would be willing to pay for this coding.
sincerely,
greg aiken
