Hello Steffen,
I just committed a small security check which should solve the decrease
in rendering speed.
If you like you can just update the file:
<YourSourceDir>\mitk\Core\Rendering\mitkSurfaceMapper2D.cpp
Or you can replace the lines 182 and 183 in the same file with:
// check if the scalar range has been changed, e.g. manually, for
the data tree node, and rebuild the LUT if necessary.
double* oldRange = lut->GetTableRange();
if( oldRange[0] != scalarsMin || oldRange[1] != scalarsMax )
{
lut->SetTableRange(scalarsMin, scalarsMax);
lut->Build();
}
(The rebuild is necessary in some rare cases where the range changes
quite often, but was for sure not intended in every rendering cycle).
Best regards,
Tobi Schwarz
