<div dir="ltr">HI Noè,<div><br></div><div>You can do an overall like this several ways. One way is to create a Camera (with otho projection) and subgraph to render the widgets and assign this Camera to the GraphicsWindow and set the Camera's RenderOrder so it get drawn last. Another way is create another View and then have this Camera below that. </div><div><br></div><div>I think the osgsequence and osgtesselate examples illustrates this type of usage case. Do a search for Camera in the examples should illuminate other ways Camera's are used.</div><div><br></div><div>To toggle on/off the widget overall simply set the Camera's NodeMask to 0x0 for switching it off, and back to 0xffffffff (or any non zero should also do) to switch it back on again.</div><div><br></div><div>Robert.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, 17 Aug 2019 at 11:58, Noè Murr <<a href="mailto:noe.murr@outlook.com">noe.murr@outlook.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi,<br>
<br>
I'm trying to resolve a complicated task.<br>
<br>
I have a Graph that will be rendered by 4 cameras in 4 different views<br>
using a composite viewer (see the first attachment).<br>
<br>
I want to render a 2D element that expands on all the views as you can <br>
see in<br>
the second attachment.<br>
<br>
Is there a way to do that in OpenSceneGraph?<br>
<br>
Cheers,<br>
Noè Murr<br>
