<DIV>Hello Thomas,</DIV>
<DIV> </DIV>
<DIV>Your problem was disscused many times in this mailing list. One process in
Windows x86 (NT based 32 bit) cannot use more than 2Gb of memory, and the
system itself - more than 4Gb (usually even less - near 3.2Gb). One
possible solution I know is using Windows x64 or some Linux. The other -
reducing the size of your dataset. :(</DIV>

[vtkusers] large data sets and memory</DIV>

<DIV>
<DIV>hi,<BR><BR>this is the first time, I write to the list and I think my
question <BR>could sound a little bit "stupid". my current problem is, when i
load <BR>large datasets there is a problem with the memory allocation. my
<BR>programm crashes on the update call of the vtkImageData. I tried it in
<BR>different ways and none worked on large data sets. small data is
<BR>processed correctly. Attached you find some code snippeds, on the update
<BR>call my program dies.<BR> <BR> vtkImageData* volume= new
vtkImageData ;<BR> volume->SetInput( centerImage->GetOutput()
)
;<BR> volume->Update();<BR> <BR> vtkImageDataStreamer
*ids =
vtkImageDataStreamer::New();<BR> ids->SetInputConnection(centerImage->GetOutputPort());<BR> ids->SetNumberOfStreamDivisions(200);<BR> ids->UpdateInformation();<BR> ids->GetExtentTranslator()->SetSplitModeToBlock();<BR> ids->Update();<BR><BR> vtkMemoryLimitImageDataStreamer*
mlds =
<BR>vtkMemoryLimitImageDataStreamer::New();<BR> mlds->SetInputConnection(
centerImage->GetOutputPort() ) ;<BR> mlds->SetMemoryLimit (
10000 ) ;<BR> mlds->Update();<BR><BR>mybe it is a problem in my
concept. i want to load a dataset with a <BR>resolution of 512 x 512 x 1024,
are there other ways to handle such a <BR>load of data?<BR>my dev environment
is visual studio 2005 on winXP SP2<BR><BR>thanks for any information and
suggestions<BR>_______________________________________________<BR>This is the
