All,
I'm reading a 512 x 512 x 176 image volume using
vtkImageReader2. I'm using Python ( reading in an image volume is the
first step in my GUI and therefore I'm using Python and TkInter). I did
timings using vtkTimerLog with start/stop just around the "reader
Update" line of code and it took me 136.6 seconds to read in the image
volume. Here's some additional info. : Image Data Type = Unsigned Short
and Size = 90,112 Kb and I'm using Windows with VTK built using
Microsoft Visual Studio 2005.
I did make sure that my Python Wrapping variable (PYTHONPATH) was
pointing to the Release libraries and I used the ReleaseDataFlagOn for
vtkImageReader2. The image is stored on a different drive and I have
mapped the drive to my computer using Windows' "Map Network drive". I'm
on a 10Mbps network and I have 1Gb of RAM on my computer. 136 seconds
still seems too long to read in a relatively small data set. Can someone
help me figure out what's going on and help me speed up the process ?
Thanks
Prashanth
