[vtkusers] Can this be done with VTK?

[Roger Blum]

Hello,

I 'm completely new to VTK and just about to evaluate it for the following purpose:

I intend to build a graphical interface for a simulation software which has (beside others) the following caracteristic:
- use of a digital elevation model (for 3D renderings)
- use of TIFF images as background (tiled maps)
- actors are displayed as a symbol and can move 
- actors carry information; user can click on actor to display the information
- refresh every 5 to 10 seconds (eventually faster)
- the user must be able to switch from 2D to 3D
- the user must be able to zoom 
- some data to display has to be read from a database

The typical simulation area consists of 5 to 10 TIFF images (about 10MB each). There are about 100 actors moving in this space.

My questions about vtk and Tcl:
- Can vtk together with Tcl be used to build this type of interface?
- Can vtk handle this amount of data (especially the TIFF images)?
- Are refreshs critical?

Any hint or idea how to do it is very much appreciated.

Roger
