[Robert Osfield]

HI Denis,

I cannot comment on specific of librocket.

If you want to use 2D elements in a 3D scene the standard way of doing
this is to use a Camera that sets the project and view matrices to
creates a 2D projection.  The osghud example illustrates how to do
this.  Perhaps this would be useful to you.

The other alternative is to simply use the OSG's native osgWidget NodeKit.

Robert.

Hi Robert,

Implementation librocket, which are published them in order. Problem is only in 
the GUI display is on the node that rotates around the axis XYZ. Myself but 
needs to appear as a 2D GUI, something like over the base OSG viewport. I 
should if you would like to display scores and other information in the game, 
so I do not want the information to be rotated in any direction but to always 
shows at front. Of course this applies also to menus, settings, etc. ... OSG'm 
not so good, I learn, so do not know how do I do this. I tried to add another 
camera and to hang it on the GUI but I failed. It is surprisingly interesting 
that any other GUI has a problem with that it is not possible, or is it 
difficult to implement 3D as a way librocket again not possible to implement a 
2D? Due to poor English and lack of tutorial and guidance in my language, I do 
not fail. Should you ever been so good and tried to advise how to do it, it 
would be cool.

Thank you!

Cheers,
Denis

I can't personally help with librocket as I've never used it. Perhaps
others can contribute their experience or suggestions for
alternatives.

Hi,

I am sorry. Those rights, I need advice. I do not know how much English use 
Translate. I tried librocket implement the OSG but it did not like it. What you 
have here 3D GUI. I would like to but needed the implementation to 2D. I was 
able to implement 2D + ImGui OSG, SFGUI + OSG, MyGUI + OSG but I wanted to try 
librocket. You would not know how you ever 2D + librocket OSG? Thank you

Thank you!

You added the above useless statement to a 5 year old long dead thread
in the forum.  Are you hoping for a reply?  Are you just trolling?

If you want help with an issue the first thing you need to do is craft
a post that contains actual useful information so that others can
understand what problem you have.

Hi Martin,

I tried adding a few different controls types to the demo.rml file - checkbox, 
radio button, select list, and button.
Button did work OK, although the text on the button would appear and disappear 
as I hovered over it.
Radio buttons, select, and checkboxes would not render at all however.

Cheers,
David

[David Wilson]

Hi Martin,

I just tried out your sample. This is exactly what I'm looking for, for a game 
I'm working on. Looks super slick.

One thing I did have to change before I could compile the sample - in 
CMakeLists.txt, I had to change:
SET(USE_OSG_GA   0)
to
SET(USE_OSG_GA   1)

(I got the latest version of the sample from the SVN trunk.)

Thank you!

Cheers,
David

 I am still improving osgLibRocket, subversion address:

 https://dtentity.googlecode.com/svn/trunk/source/osgLibRocket

 Recent improvements:

 * No longer re-adding osg geometry every frame, instead
 increasing/decreasing reference count on geometry, only removing geometry
 when not referenced during the frame
 * static compiling now possible
 * No longer holding geometries in a std::map for storage, instead using
 libRocket handles to hold geometry
 * Experimental: Use a shader to do screen transformation of libRocket
 geometries. No real performance gain, also scissoring does not work yet.
 Commented out in RenderInterface.cpp
 * Integration with dtEntity system: Use JavaScript in libRocket RML files;
 use libRocket elements as HUDs over osg scene elements to attach text,
 energy bars etc

Re: [osg-users] I made the libRocket GUI library usable with OSG

[Martin Scheffler]

Some improvements to osgLibRocket:
* Should now work cleanly in non-singlethread mode
* scissor tests now work, widget contents is now correctly hidden
* lots of small stuff

Known issues:
* When starting OSG in fullscreen mode then fullscreen gui does not appear. 
Somehow the initial screen size is not correctly given by OSG.
* Demo crashes on shutdown on linux, it seems I don't delete stuff in the 
correct order.

To start demo: 

./sample-drag --assetsPath path-to-librocket-assets-folder

It won't at all. I just need to find the time, or at least the funding
so I can MAKE time. :)

The next version will be much better, as I've learned exponentially
since then...

 About the missing CMake variables: Are you using the advanced mode in

Whoops. Got it...

Having made osgWidget all those years ago it really makes me sad when I
see stuff like this, but the bottom line is osgWidget simply isn't good
enough. I've wanted to, for a long, long, time, go back and make it
better. :)

HOWEVER, having said that, this is actually a great little library. Not
bad at all, the design seems very solid! I think if you figure out the
issues with cleaning up, it could become quite popular in the OSG
community.

BTW: I can't actually get it to compile yet (though I can run the Rocket
examples just fine); CMake won't find/define LIBROCKET_* variables...

 Martin

Hi Martin,

This sounds very interesting! I've always wanted to be able to create
interfaces for my application using HTML/CSS. I'm definitely going to have a
look at this.

Thanks,
