<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I 'm completely new to VTK and just about to
evaluate it for the following purpose:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I intend to build a graphical interface for a
simulation software which has (beside others) the following
caracteristic:</FONT></DIV>
<DIV><FONT face=Arial size=2>- use of a digital elevation model (for 3D
renderings)</FONT></DIV>
<DIV><FONT face=Arial size=2>- use of TIFF images as background (tiled
maps)</FONT></DIV>
<DIV><FONT face=Arial size=2>- actors are displayed as a symbol and can move
</FONT></DIV>
<DIV><FONT face=Arial size=2>- actors carry information; </FONT><FONT
face=Arial size=2>user can click on actor to display the
information</FONT></DIV>
<DIV><FONT face=Arial size=2>- refresh every 5 to 10 seconds (eventually
faster)</FONT></DIV>
<DIV><FONT face=Arial size=2>- the user must be able to switch from 2D to
3D</FONT></DIV>
<DIV><FONT face=Arial size=2>- the user must be able to zoom </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT><FONT face=Arial size=2>- some data to
display has to be read from a database</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The typical simulation area consists of 5 to
10 TIFF images (about 10MB each). There are about 100 actors moving in this
space.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My questions about vtk and Tcl:</FONT></DIV>
<DIV><FONT face=Arial size=2>- Can vtk together with Tcl be used to build this
type of interface?</FONT></DIV>
<DIV><FONT face=Arial size=2>- Can vtk handle this amount of data
(especially the TIFF images)?</FONT></DIV>
<DIV><FONT face=Arial size=2>- Are refreshs critical?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any hint or idea how to do it is very much
appreciated.</FONT></DIV>
