I have a vtk showing a particle model of a screw being twisted. I tried to insert an stl file for a screwdriver in the correct position and tried rotating it at the same rate as my vtk file. I added a Filter->Transform->Rotation(2) about z-axis, and added the final angle on the animation panel. I assumed the rotation would occur about the center of the stl itself but the stl started spinning about an unknown axis instead.
How do I figure out which axis the stl is moving about?
I tried to change the origin in the transform filter but it doesn’t seem to be working.
Could you perhaps send a screenshot to indicate how to use the RotateAroundPoint mode?
