Graphical "Post-it" Note

[java3d-interest]

Hello all,

This time I have a real question that has nothing to do with any "buggy" code on my behalf :).

I need to create an "input notes" Object that is attached to a specific area on a displayed Model. A translucent "box" that will allow the user to enter text from the keyboard directly and display it. The "text box" should also rotate with the model.

I was wondering if anyone had any ideas on how to allow for the direct entry and display of text using Java3D. I am aware of Text2D/3D Objects but really need something like a "post-it" note that can be written on directly on the displayed.

Thanks.

I have an idea that I hope someone can help me with :).

What about embedding a JTextField in a Java3D rectangle? This rectangle could then be attached to the current Model display.

Does anyone know if this will work - particularly the embedding of the JTextField in a Java3D Polygon ?

Thank you.

This is not trivial task I guess... The only thing which comes into my
mind is this one:
https://jogl-demos.dev.java.net/ the demo called XTrans.

but it is not Java3D, it is JOGL...

NO! :) Now I recalled! It was a nice demo from jMokey Engine -
TestJMEDesktop.

http://www.jmonkeyengine.com/webstart/jmedemo.php?TestChooser

I don't think Java3d can do that.

Thank you :)

I will take a look at it - Do you know if JMonkey has NURBS trimming?

Once again, thank you.

Very interesting !
 But seems it is rendering the swing components in a 2D plate in front of 3D, like a HUD, isn't ?

Nope :) If you click "toggle fullscreen" button and use WSAD + arrows
you will see that the gui controls are located on the rectangular
desktop which is just an object in 3D space - not HUD.

Another idea - kind of a hack I guess :)

What if I just attached multiple Text2D Objects (one for each line of text) to a single BranchGroup Object and then attached that to the main "root" Group Object of the model ? I would like to have a scroll-like feature but will settle for just multiple lines of text in the same area if possible.

Is there a way in Java3D Text2D Class to ensure that the text Objects can be moved one line down (for each text line - like a carriage return)?

Thanks.

If not you can emulate it with TransformGroups.

Another way to go might be:

1. render the component into BufferedImage
2. make a Texture2D from BufferedImage
3. apply Texture2D to Shape3D

I have never tried this approach - it is just a quick thought. How to render into BufferedImage:

Thank you very much Dmitri. You have been extremely kind for the responses.

Quick question:

Does Java3D have a HUD option ?


Once again, thank you.
