[vtkusers] vtkFixedPointVolumeRayCastMapper How to GetGradientEstimator ??

[Sercani]

Hi;
I don't know the problem about GetGradientEstimator, but i am sure it is
something like the SetVolumeRayCastFunction problem...
SetVolumeRayCastFunction is not a member of
vtkFixedPointVolumeRayCastMapper, it is vtkVolumeRayCastMapper's
function...You can use the blending mode settings to set the projection
style(mip, minip or composite)...I think you only changed the mapper and
didn't change the rest of the code..
 	 vtkFixedPointVolumeRayCastMapper
*raycastMapper=vtkFixedPointVolumeRayCastMapper::New();
       //vtkVolumeRayCastMIPFunction
*mipFunction=vtkVolumeRayCastMIPFunction::New();
	 //mipFunction->SetMaximizeMethodToScalarValue();
	 //vtkVolumeRayCastMapper
*raycastMapper=vtkVolumeRayCastMapper::New();
	 raycastMapper->SetInputConnection(imageCast->GetOutputPort());
	 raycastMapper->SetSampleDistance(1.0);
	 //raycastMapper->SetVolumeRayCastFunction(mipFunction);
	 raycastMapper->SetBlendModeToMaximumIntensity();

Hi 

I used vtkVolumeRayCastMapper now I want to use
vtkFixedPointVolumeRayCastMapper.

I got some compilation errors   :

'GetGradientEstimator' : is not a member of
'vtkFixedPointVolumeRayCastMapper'	


'SetVolumeRayCastFunction' : is not a member of
'vtkFixedPointVolumeRayCastMapper'	


How to solve these errors?

Thank you in advance
