Hi Roy, as you use forum I do not see your email address ( otherwise I would likely send personal message ) but anyway, might be that someone else will benefit of such discussion in future in similar situation.
one quite unusual, but useful example for your purposes was discussed in discussion group some time ago - to use gldirect to run osg to translate opengl calls to dx, the example claimed to be working well ( I did not try it though as it was over 1 gb size and was offered over very slow connection ) You may try this way as it proved to be working for dx9 and thus might prove most easy way to follow in case you do not use shaders in your osg output as gldirect supports only fixed pipeline ( gldirect could be taken here https://raw.githubusercontent.com/bfosterjr/windowsrtdev/master/libs/gldirect5/src/gldirect5.7z ) otherwise there are quite few examples to use nv extention besides a lib I already linked there is also: https://github.com/tliron/opengl-3d-vision-bridge/blob/master/opengl_3dv.c While to insert it into already existing code of the game might be intimidating the idea is quite straightforward: dx creates a texture which is then shared with opengl as fbo and as osg supports rendering to fbo a code to glue rendering might be inserted to osg setting rendering target as that provided by dx fbo, after rendering to fbo, the texture can be used in dx, such as being attached for hud over already rendered scene.
