[vtkusers] How erode or dilate a volume?

[Francois Louis LAILLIER]

Hi Vtkrusers!

 

 I open binary files, render them, threshold the volume.

 

 Now, I want to erode the noisy data.

 

 After my threshold I erode data like that.

 

 ###################CODE##################

 

 Blablabla

 

 threshold.Update

 

 Dim erode As vtkImageDilateErode3D

 

 Set erode = New vtkImageDilateErode3D

 

 erode.SetInput threshold.GetOutput

 

 erode.SetKernelSize 3, 3, 3

 

 erode.SetErodeValue 0

 

 erode.SetDilateValue 0

 

 erode.Update

 

 ##################"#######################

 

 It Doesn't work.WHY?

My volume is rendered but without difference between only threshold and
with erodes.

 

I change kernel size without success, I change seterodevalue without
success to.

 

 Can you explain me the arguments of seterodevalue or setdilatevalue.

 

 Thanks' in advance

 

 Best regards, Francois Louis.
