I use a circle object to represent my custom light source. it’s a directional light so I need somehow to define direction. Usually we just use transformation matrix of object and some base vector. But it looks like there is no way to get ‘transformation’ from Rhino object.
How it can be achieved in Rhino?
I have only one idea: add special arrow-ended line and join it with light gizmo and use this line as a direction vector. If it sounds good then how can I join two geometries or objects into one?
