[vtkusers] Actors to busy drinking in the green room??

[John Platt]

Hi Mark,

I am not sure if the same mapper/actor is being rendered in the
different views but you could try
vtkMapper::GlobalImmediateModeRenderingOn().

HTH

John.

Hello all,

I have a rather bizarre effect going on with actors diasspearing /
changing colour without user prompting (generally as a result of
rotation/dollying). I'm rather lost as to why it is occuring.

I'm using the MFC document-view arcitecture, and have 4 views, all
containing the vtkRenderers. The aim is to have each view containing
the same scene viewed from a different aspect. To save memory (and
time) the document is responsible for creating each of the vtkActors
within the scene. These are then passed (well a pointer to them is
passed), on request, to each view so that the actor can be added to
its renderer.

This seems to work ok, except that when I perform some interaction on
a view, some actors disappear or change color from view I'm
interacting with. I'd appeciate some suggestions - I'm sure it will
relate to how I'm passing actors around, but I don't see why it
should?!

If you need any more information about what I've done, feel free to
ask....
