Hi,

I've seen this many times:

moi.geometryDatabase.getSelectedObjects()

but is there the equivalent of this:

moi.geometryDatabase.getVisibleObjects()

Just for fun I tried that but it generated an error.

Thanks.

Frederick

Hi Frederick,

What is your definition of a visible object?

Do you mean objects that don't have obj.hidden == true ?

Or objects that are inside of or intersect with the field of view of a viewport?

Or objects that have some pixels being drawn on screen so not behind another object?

Hi,

Just those that are not hidden.

I know I can just iterate over all objects and check the hidden property but I thought, since there was a function that did that for the selected property perhaps there was one for the "visible" property (hidden = false).

I got it working doing the above but it did lead to a question.

When setting the hidden property to FALSE I found that I had to do the same for all sub-objects for the object to be displayed.

The question: when setting the hidden property to TRUE does that automatically set the hidden property for all sub-objects?

Thanks.

Frederick

Hi Frederick,

It depends on the object type - on a group setting group.hidden = true will set hidden = true on the immediate children of the group.

On other objects no - on a solid for example setting solid_obj.hidden = true does not set .hidden = true on all of its face and edge sub-objects.

A sub object is effectively hidden if either it or any of its parent objects has hidden == true.

Shouldn't normally be needed to do that unless you've set hidden = true on all the sub objects yourself.

For example, start with a blank scene, draw a box, and hide it (using regular UI).

If you then run this script it should show the box, by only setting .hidden = false on the top level box object only:

var box = moi.geometryDatabase.getObjects().item(0); box.hidden = false;

Hi Michael,

Thanks for all the information about how the hidden property works.

I will re-visit my code and see what I did wrong, to require "un-hiding" all of the sub-objects.

You should setup a "tip jar" for all of us folks that learn so much from you.
