[vtkusers] vtkOpenGLGPUVolumeRayCastMapper / Error

[Jean-Hugues Royer]

Hi,

Sometimes rendering a volume results in an stdout error from 
vtkOpenGLGPUVolumeRayCastMapper which is "Loading the streamed block 
FAILED!!!!!".

It is initiated by this code:

// Load the block
if(!this->LoadScalarField(this->GetInput(),this->MaskInput, 
blockTextureExtent,
                           volume))
{
cout<<"Loading the streamed block FAILED!!!!!"<<endl;
}

Do you happen to know what it means ?

Regards.
