[vtkusers] Geforce 6600 and isosurface display problem

[Wagner Sales]

Hi Binjie,

To help you are important more information about your system. I'm a 
Linux user, and at this land, that's appears a driver instalation 
problem, or a link problem, and not realy a hardware or VTK problem. 
Then, first I'll advice you to recompile and relink ( may be only relink 
solve the problem ) your application at your new system.
Whenever, to ask this question some informations are important:
a) How operanting system you use? ( version, if linux, kernel version )
b) How driver version you use?
c) Only the mentioned case have problems or other applications which use 
the accelerated hardware ( e.g. games ) was presented problems?

Regards,
Wagner Sales
