If I understand you correctly, you want an independently-manipulable 3D space with its own rendering window that seamlessly integrates into the SL UI, right? For showing things like texturing previews? Since the SLUI is drawn entirely inside of a single OpenGL framebuffer, you'll need to get your scene into a texture that can be drawn into that buffer. My OpenGL is very rusty, but as far as I know the best way of doing it is to create an offscreen framebuffer, bind the buffer to a texture, and then render your sub-scene into it. You then have a texture you can draw into the main viewport that contains an image of your sub-scene. I haven't looked into the rendering system in the SLViewer at all, but a brief search using what I know of GL framebuffer rendering indicates that the LLRenderTarget class seems to be designed for exactly this purpose, and appears to be used to generate the main world-view in LLViewerWindow. Presumably one could harness this same functionality to create an LLUICtrl-derived object that could go into in-engine dialog boxes. Of course, you'd need to replicate your own scene graph for it as well. It's a complicated request, but a lot of the tools you want are already available in the codebase for extending. _______________________________________________ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/SLDev Please read the policies before posting to keep unmoderated posting privileges
