100% solved with this suggestion.<br>
The good thing is that I got my 512 x 512 x 194 (short) volume rendered in a<br>
good quality and performance.<br>
<br>
But I still have problems with other, larger datasets:<br>
the first: 512 x 512 x 1359 (short) volume. It is so slow that you cannot<br>
even call it "interaction".<br>
the second: 512 x 512 x 1775 (short) doesn't even render (crashes).<br>
<br>
My system is similar to Elvis Chen's:<br>
VTK, rebuilt usign DirectX SDK from June 2010 as proposed here.<br>
Win 7 64-Bit<br>
Xeon 2,7GHz 4 core<br>
4GB RAM<br>
2 x NVIDIA Quadro FX 3700 with 512MB video RAM<br>
<br>
I've been wondering, if VTK doesn't take use of both GPUs together and the<br>
512MB video RAM of one is the bottleneck.<br>
I wrote a pure-VTK small test-program to render a volume. It means<br>
dicomReader -> mapper -> volume -> renderWindow.<br>
<br>
I observed the behavior of VolView 3.4 while rendering and interacting. Even<br>
with option "Use GPU rendering" unchecked I see alot of GPU activity (>90%)<br>
while interacting (watched using "Process Explorer"). This doens't happen<br>
when I load the same volume with my application (2-3%). What does VolView do<br>
different?<br>
<br>
I would appreciate any idea on how to explain this behavior. Thank you =)<br>
