What is the best way to add a rotation handle to my object?
Sizing and moving is ok, but how to add a rotation handle?

Hi Pim,

Objects are usually rotated with the Rotate tool.
Do you want to rotate the object or rotate a component/parameter of the object?

Spherical handles can be declared with the HandleInfo type.
Look at the DoubleCircle SDK example for a way to implement handles with HandleInfo/GetHandleInfo()/GetHandle()/SetHandle() and DetectHandle()/MoveHandle().

DetectHandle()/MoveHandle() shouldn't be implemented in objects but the Python API doesn't use the automatic Handle interface currently for ObjectData plugins. It is supported for FalloffData plugins only.

In GetHandle() an HandleInfo can be initialized with info.type = HANDLECONSTRAINTTYPE_SPHERICAL
Then in MoveHandle() the info.CalculateNewPosition() for the handle will return a position calculated with a spherical constraint.

Hi Yannick,

I agree with you. Stick to using the Rotate Tool is the best thing.

Thanks, Pim
