Rotate around a body axis
Ciao Stefano,
I am playing around with FOSSIL and in particular with rotate(matrix=R). It looks like that if I pass a rotation matrix it will rotate around the standard coordiante system axis, while I am more about to rotate around a body axis. I have tested also rotate(axis=ax, angle=theta), fiding the same result. The rotation si performed always around ex, ey, ez. Do you have any fix for this?
Here an example where I am rotaing a disk around y axis:
I am wondering if you can add a function to specify the center of rotation and the rotation matrix that can be handy :)

Hi, it passed a long time since the last inspection of FOSSIL (I am rarely using it, currently I have been forced to use CGAL), thus I am not sure of what was implemented. Anyway, I can try to implement what you have requested. I am not sure about the time I need for doing it, please be patient.
Kind regards
So there is nothing wrong in your code, of I ask paraview to rotatr around an axis I'll get the same results. I am just looking to rotate around the center of mass. I think I can rotate and then translate back of I know the center of rotation used by Fossil, meed to think about it a bit.

Ciao Stefano,
I think a dummy way to do this operation is translate origin + rotate + translate barycenter.
