Hello,
I'm having troubles with AIS_Trihedron + zoom persistence. I don't understand clearly how to make it work.
I display an AIS_Trihedron located at some gp_Ax2 placement, this is working fine.
Now to make that 3d object size "independent" from view zooming :
aisTrihedron->SetTransformPersistence(
new Graphic3d_TransformPers(Graphic3d_TMF_ZoomPers, anchorPoint));
What point should I give as the "anchor point" ?
I've tried to tweak also with AIS_Trihedron::SetLocalTransformation() but always getting something wrong.
Please can someone help here ?

The anchor point should be the position of the AIS_Trihedron, which is gp_Ax2::Location() you defined before.
