Query If An Object Is Being Drawn

[andimation]

Hey

Is there a way to know if an object is being drawn in a viewport. Obviously there are many ways to make an object invisible. If I use the mel command "ls -visible", it will still return objects which have been hidden using draw overrides. Also the parent objects visibilty comes into question.

Is there a way using M3dView to query if an object is truely visible? I could write a lengthy mel script but it seems overkill.

Thanks

Andy
