How to transform a model with pqPipelineSource

Development
1

Hello,

I got a cube pqPipelineSource, I need to transform it now (eg: rotation), I can transform by getting vtkActor; but ParaView is very well isolated from VTK data. In response to this situation, what does ParaView recommend?

Thank you!

When Tramsform uses Rotate, which axis is rotating around it? I want the bottom of the cylinder to be the same as the plane of the model, but after the rotation, the distance becomes farther.

X, Y or Z

I want the bottom of the cylinder to be the same as the plane of the model, but after the rotation, the distance becomes farther.

I do not reproduce this behavior. Please share a state file or steps to reproduce.

Sorry, I didn’t say it clearly!

Let me talk about what I am doing! Add a stl model, then pick a coordinate point on the model, save the normal vector in the cell where the coordinate point is located, add a Cylinder to the coordinate point, I need to make the direction of the bottom surface of the Cylinder the same as the normal vector. The above work is implemented in C++ code.

Question: How do I use the code to adjust the direction of the bottom of the cylinder to be the same as the normal vector?
