Yesterday I started to make a custom object (inherited from
CRhinoSurfaceObject) that is a wrapper for a surface spline object from another library. Works perfectly, except that when I move or otherwise transform the object, the wrapped object needs to be updated too.
Now, in the C# implementation of a custom object, there are the
OnSpaceMorph methods, and these allow me to do just that: hook into a transform/morph operation. I’m sure that this is possible in C++ too, but I can’t find how.
