[osg-users] shipping custom file format plug-ins as part of an OSG application binary?
Hi, let's say I have developed a plug-in to read a specific file format. Is it possible to make this plug-in part of the my application binary without shipping an additionall DLL in the osgPlugins folder? The rest of OSG remains a dynamic build - only that extra plugin is desired to be statically linked with my application. How would I go about registering said plug-in with OSG so it's getting used?

Re: [osg-users] shipping custom file format plug-ins as part of an OSG application binary?
Hi Christian, Yes, this is possible. Once you have implemented your custom osgDB::ReaderWriter, you can use the osgDB::RegisterReaderWriterProxy to globally register the class. For example, if your custom class is named MyReaderWriter, just add the following in your source file: static osgDB::RegisterReaderWriterProxyMyReaderWriter g_MyReaderWriterProxy; This essentially adds an instance of your custom loader class with the global osgDB::Registry instance. As long as your class properly implements the acceptsExtension method, your application should now be able to handle the specified file format.

Re: [osg-users] Slaves, RTT, and HUD
Hey Robert, Thanks for the reply. I've finally gotten around to implementing a solution to this problem. Unfortunately, when I added the text HUD camera as a child to the RTT main camera, I still wasn't seeing my HUD. However, if I turn the HUD camera into another RTT camera and attach it to the texture of the main RTT camera (with only the GL_DEPTH_BUFFER_BIT set as the clear mask) then it works great!

Here's what I have: - A slave camera that renders the main scene to a texture. - A slave camera that renders a screen-space mesh with the above texture applied to it. - A lone camera acting as a HUD that I would like to render to the texture, but can't seem to get this working. I've tried attaching the lone camera as a child of the RTT camera, and that doesn't seem to work. I can get it to work when the RTT camera isn't a slave, but as soon as I make it a slave it doesn't work. I can get the HUD to render directly to the screen when I attach it as a child of the screen-space mesh camera, however it won't appear distorted.

What I've tried so far is... 1. A normal Viewer class with two Cameras in the scene graph, one on a pre-render pass that renders the main scene to a texture and one on a post-render pass that renders a screen space mesh with the other Camera's texture applied to it. 2. A Viewer class with two Cameras attached as slaves, with the same pre- and post-render setup as above. The RTT (pre-render) Camera has the main scene as the child and the mesh (post-render) Camera has just the screen space mesh as a child. For these, I can get a HUD displaying on the following Cameras when I attach it as a child to the respective Camera: - 1's pre-render Camera, attached to the texture and set up as a FBO - 1's post-render Camera - 2's post-render Camera For my HUD, I'm simply creating a Camera with an Absolute reference frame, orthogonal 2D projection, and on the post-render pass. See osghud.cpp, as I've pretty much copied that with the modification of an optional Texture parameter. The part I'm having trouble getting to work is getting that HUD rendering to a texture when that RTT Camera is a slave of a View. The thing that baffles me is I can get it working on a non-slave RTT Camera in the same way, and I can get it working on a non-RTT slave Camera, but not the intersection of both. I've tried searching for a similar solution, but I haven't found anything for this specific scenario. Any help or direction would be appreciated. :) ___ osg-users mailing list osg-users@lists.openscenegraph.orgmailto:osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.orgmailto:osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

If I remember right, they were free to use at least for academic stuff. I think Zhuwan is still around on the list, he could probably answer the question better.

Hi Nick,
Is this what you are looking for?

Hi Community,
what was the way to have textures cached and reused on load? any hint?
Thanks a bunch!

Re: [osg-users] Texture cache question
Hi Nick, The osgDB::SharedStateManager might well be what you are looking for. It's not something I wrote or have used so can't provide lots of details on how best to use it, but I can say it's role is for sharing state between an already loaded scene graph and new loaded scene graph. Sebastian's suggestion about the using the Object Cache feature of osgDB::Registry is useful too for sharing osg::Image, which will help the SharedStateManager spot places where osg::Texture can be shared when they use the same osg::Image.
