I want to create a model node which includes two or more cylinders. Is that possible ?( I don´t want a node per cylinder)
Would you like to create a cylinder with a cylindrical hole in it? You can create that by appending output of vtkClyinderSources, with the internal polydata turned inside out using vtkReverseSense.
I want to create 2 or more independent cylinders into a single Model node.
OK, then just append the output of the cylinder sources by using vtkAppendPolyData and set its output as input of the model node.
Thank you so much! It worked!
