    Hi,

    DrawPolygonObject doesn't draw the object, if the center of the world is outside the view, although all polys are in the visible area. The object is not inserted into the document.

    My idea to fix that, is to position the object's origin in the middle of the polygons. But I hope to get another solution here, because that wouldn't work in all situations.

    Any ideas?

    Yes, this seems to be the standard behavior for DrawPolygonObject() - if the origin is outside the view frustrum, the entire object is clipped. My Tool does this as well and have never found a way around it.

    Hopefully someone with a way to solve this will respond.

    I can confirm this as well. I will ask the developers for a workaround.

    cheers,

    Ok, to make it work Cinema needs the bounding box of the polygon object. You do this by submitting the MSG_UPDATE message after you have changed or created the polygon object.

    Call

    mypoly->Message(MSG_UPDATE);

    after the polygon creation/change.

    cheers,
    Matthias

    Thanks, Matthias!

    Will try this immediately and let you know the results.

    That works! Just calling obj->Message(MSG_UPDATE) after each obj->SetMg() and after creation. No more full clipping when the center goes out of view.

    Thanks much!
